Quick Summary: Export reviews from any of 11 platforms to CSV using Comment Exporter, upload the file to Claude, and run targeted prompts to extract sentiment patterns, feature requests, competitive intelligence, and actionable insights. Claude's 200K token context window lets you analyze 5,000+ reviews in a single conversation -- no batching required. This guide includes 10 copy-paste prompts that work immediately.
Why Claude AI for Review Analysis?
There are several large language models capable of analyzing customer reviews. ChatGPT, Gemini, and others all handle the task. But Claude, built by Anthropic, has specific architectural advantages that make it uniquely suited for review analysis at scale.
The headline advantage is Claude's 200K token context window. That translates to roughly 150,000 words of input in a single prompt. In practical terms, you can upload an entire CSV file containing 5,000+ reviews and analyze them in one conversation -- no splitting, no batching, no losing context between chunks. Most competing tools start struggling above 1,000 reviews. Claude handles five times that without breaking a sweat.
This matters because review analysis produces better results when the model can see the entire dataset at once. Patterns that only emerge at scale -- a complaint that appears in 3% of reviews, a feature request that clusters around a specific date range, a subtle sentiment shift between verified and unverified purchasers -- get lost when you split data across multiple conversations. Claude keeps the full picture in view.
Beyond context length, Claude brings several other strengths to review analysis. It follows complex instructions precisely, which means your structured prompts produce consistently formatted output. It excels at categorization tasks, sorting hundreds of individual complaints into coherent themes without dropping items or creating duplicate categories. It handles CSV parsing natively, reading column headers and maintaining the relationship between review text and metadata like star ratings, dates, and verification status. And it tends to hallucinate less than other models -- when Claude says 34% of reviews mention a specific complaint, that number is more likely to reflect the actual data.
Claude also offers an Artifacts feature that generates tables, charts, and formatted documents inline within the conversation. When you ask Claude to produce a sentiment breakdown table or a competitive comparison matrix, it renders them as structured visual elements you can copy, export, or reference -- not just plain text approximations.
If you have already read our ChatGPT review analysis guide, think of this as the companion piece. Same workflow philosophy -- export, upload, prompt -- but optimized for Claude's specific capabilities. The prompts in this guide are tuned to take advantage of Claude's strengths: large context processing, precise instruction following, and structured output generation.
What You Will Need
The entire workflow requires exactly two tools.
- ✓Comment Exporter -- A Chrome extension that exports reviews and comments from 11 platforms (Amazon, Reddit, YouTube, Steam, Etsy, Product Hunt, Quora, Hacker News, Facebook, Google Maps, and Shopify) to CSV or JSON files. Reddit scraping is free. All 11 platforms are available on the All Access plan. Install it from the Chrome Web Store.
- ✓Claude -- Anthropic's AI assistant. The free tier gives you access to Claude 3.5 Sonnet with file upload support and limited daily usage. The Pro plan ($20/month) unlocks Claude Opus 4, significantly higher usage limits, and the Projects feature for persistent analysis across conversations.
That is the complete toolset. No coding, no API keys, no data science background. If you can install a Chrome extension and upload a file, you can run every analysis in this guide.
Optional but useful: Google Sheets or Microsoft Excel for previewing and filtering your CSV files before uploading them to Claude. This step is not required but can help you focus your analysis on specific subsets of your data.
Step 1: Export Your Reviews with Comment Exporter
Claude cannot analyze reviews it cannot access. Platform review pages are locked behind pagination, infinite scroll, and dynamic loading. The first step is getting that data out of the platform and into a structured file that Claude can read.
The Comment Exporter Chrome extension handles this across all 11 supported platforms. Here is a quick walkthrough for the most common sources.
Exporting from Amazon
Navigate to any Amazon product page with reviews. Click the Comment Exporter icon in your browser toolbar and start the scrape. The extension automatically paginates through all review pages -- even products with thousands of reviews. Your exported CSV includes structured columns: review text, star rating, review title, date, verified purchase status, and helpful vote count. The extension supports 20+ Amazon country domains, so you can pull reviews from any market. See the full Amazon Review Scraper page for platform-specific details.
Exporting from YouTube
YouTube comments contain a different type of feedback -- shorter, more reactive, and often revealing about what content resonates with audiences. Navigate to any YouTube video, click the extension icon, and export. The CSV includes comment text, author, like count, timestamp, and reply status. The YouTube Comment Scraper handles videos with thousands of comments, including nested reply threads.
Exporting from Reddit
Reddit threads provide raw, unfiltered opinions. Comments are longer, more detailed, and often more honest than formal review platforms. Export any Reddit post to get comment text, author, score (upvotes minus downvotes), timestamp, and thread depth. Reddit scraping is free with Comment Exporter -- no Pro plan required. For specialized analysis techniques, see our Reddit sentiment analysis guide.
Other Supported Platforms
The same one-click export workflow works on Steam (game reviews with playtime data), Etsy (handmade and vintage product reviews), Product Hunt (launch feedback), Quora (answers and discussions), and Hacker News (tech community threads). One extension, 11 platforms, same CSV output format.
"Compared to other tools, the price is incredibly low for the quality it delivers. I can now export reviews from Amazon and Etsy in seconds." -- Mitran Marian
Step 2: Prepare Your Data for Claude
Claude handles raw CSV files well, but a few minutes of preparation can significantly improve the quality of your analysis output.
CSV Is the Best Format for Claude
Comment Exporter supports both CSV and JSON export. For Claude review analysis, CSV is the recommended format in almost every case. Claude parses tabular CSV data natively, reads column headers to understand data structure, and maintains relationships between review text and metadata columns throughout the analysis. CSV files are also smaller than their JSON equivalents, which means you can fit more reviews within the context window.
The one exception: use JSON when you need to preserve hierarchical thread structure, such as Reddit comment trees with parent-child relationships. For all other platforms -- Amazon, YouTube, Steam, Etsy -- CSV is the right choice.
What Columns to Include
Comment Exporter's CSV output includes all available metadata by default. For most Claude analyses, you will want to keep these columns:
- ✓Review text / comment body -- The core content for analysis. Always include this.
- ✓Star rating -- Essential for sentiment analysis and for filtering (analyzing 1-star reviews separately from 5-star reviews).
- ✓Date -- Required for trend detection and temporal analysis.
- ✓Verified purchase status -- Allows Claude to compare verified vs. unverified reviewer sentiment.
- ✓Helpful votes / like count -- Lets Claude weight high-signal reviews more heavily.
You can remove columns like author name or profile URL if they are not relevant to your analysis. Fewer columns means less token usage per review, which means you can fit more reviews in a single upload.
File Size and Review Count Tips
Claude's 200K token context window is generous, but here are practical guidelines:
- ✓Under 5,000 reviews: Upload the entire CSV in one file. Claude handles this comfortably in a single conversation.
- ✓5,000-10,000 reviews: Consider removing unnecessary columns to reduce token usage. If reviews are short (1-2 sentences each), you can often fit the full dataset. If reviews are longer (3+ paragraphs), consider splitting into two uploads.
- ✓10,000+ reviews: Pre-filter in Google Sheets or Excel before uploading. Filter by star rating, date range, or helpful vote count to create targeted subsets. A focused dataset of 3,000 relevant reviews produces sharper insights than 10,000 unfiltered ones.
For most real-world analysis scenarios, your exported CSV will be well within Claude's capacity. This is the key advantage -- where other tools force you to batch and split, Claude lets you analyze the full dataset in one pass.
"The files it spits out are perfectly formatted, no messy cleanup needed." -- Alfon Labadan
Step 3: Upload and Analyze in Claude
Getting your data into Claude is straightforward. There are two methods, and a powerful advanced option for ongoing analysis.
Method A: Direct File Upload (Recommended)
Both free and Pro Claude users can upload files directly into a conversation. This is the recommended approach for any dataset over 50 reviews.
- ✓Open claude.ai and start a new conversation.
- ✓Click the attachment icon (paperclip) in the message input area.
- ✓Select your exported CSV file from Comment Exporter.
- ✓Type your analysis prompt (see the 10 prompts below) in the message field.
- ✓Hit send. Claude will confirm it has read the file, display the number of rows and columns detected, and begin analysis.
Claude reads the entire file contents -- including column headers and all data rows -- and keeps them in context for the duration of the conversation. You can ask follow-up questions, run additional prompts, and drill into specific findings without re-uploading the file.
Method B: Paste Directly
For smaller datasets -- under 100 reviews -- you can paste CSV content directly into the chat window. Open your CSV in a text editor, select all content, and paste it with your prompt.
Here are [NUMBER] reviews exported from [PLATFORM] for [PRODUCT NAME]. Analyze them according to the instructions below.

Using Projects for Persistent Analysis
Claude Pro users have access to the Projects feature, which is a significant advantage for ongoing review analysis. Projects let you pin files and instructions that persist across every conversation within that project.
Here is how to set up a review analysis project:
- ✓Create a new Project in Claude (e.g., "Amazon Product Analysis" or "Q1 2026 Customer Feedback").
- ✓Pin your exported CSV file to the project's knowledge base.
- ✓Add a project-level instruction like: "You are a customer insights analyst. The attached CSV contains product reviews. When analyzing, always provide specific numbers, direct quotes, and structured output with clear headers."
- ✓Start conversations within the project. Every conversation will have automatic access to the pinned CSV and will follow your standing instructions.
This is powerful for iterative analysis. You can run Prompt 1 (Sentiment Overview) in one conversation, Prompt 4 (Competitor Comparison) in another, and Prompt 7 (Product Improvement Priorities) in a third -- all within the same project, all referencing the same data, without re-uploading each time. You can also update the pinned CSV with fresh review exports as new data comes in.
10 Copy-Paste Claude Prompts for Review Analysis
These are the core of this guide. Each prompt is designed for a specific analysis use case, tuned for Claude's strengths, and ready to paste alongside your uploaded CSV file. Replace the placeholders in brackets with your actual values.

I have uploaded review data for competing products in the [CATEGORY] space:
- Product A: [NAME] ([NUMBER] reviews from [PLATFORM])
- Product B: [NAME] ([NUMBER] reviews from [PLATFORM])
- Product C: [NAME] ([NUMBER] reviews from [PLATFORM])
Analyze all reviews and produce a competitive intelligence report:
1. COMPETITIVE STRENGTHS
For each product, list what customers say it does better than alternatives. Be specific -- not "good quality" but "battery lasts 2x longer according to 34% of reviewers."
2. COMPETITIVE WEAKNESSES
For each product, list where customers say it falls short relative to competitors.
3. HEAD-TO-HEAD COMPARISONS
When reviewers explicitly compare products, capture those comparisons verbatim. Which product wins on which dimensions?

Prompt 6: Review Trend Analysis Over Time
Use case: Detect whether product quality, customer satisfaction, or specific issues are improving or declining. Requires review data with dates. Particularly valuable after product updates, pricing changes, or competitor launches.
You are a trends analyst. I have uploaded [NUMBER] reviews from [PLATFORM] for [PRODUCT/COMPANY NAME]. These reviews span from [START DATE] to [END DATE].
Analyze how customer feedback has changed over time. Produce a comprehensive trend report:
1. SENTIMENT TRAJECTORY
Break down average sentiment by month or quarter. Is overall satisfaction improving, declining, or stable? Quantify the change.
2. RATING DRIFT
If star ratings are included, calculate the average rating per month/quarter. Identify any significant shifts (0.3+ stars in either direction) and correlate with review content to explain why.
3. EMERGING ISSUES
What complaints appear in recent reviews (last 3 months) that were absent or rare in older reviews? These may signal product changes, quality control problems, or new competitor pressure.
4. RESOLVED ISSUES
What complaints appeared frequently in older reviews but have decreased or disappeared in recent ones? These may indicate successful product improvements or fixes.
5. SEASONAL PATTERNS
Are there recurring patterns tied to time of year? (e.g., more shipping complaints during holidays, more returns in January, different use cases in summer vs. winter)
6. VOLUME TRENDS
Is the review volume increasing or decreasing over time? Sudden spikes may indicate marketing campaigns, viral moments, or product issues.
7. KEY INFLECTION POINTS
Flag specific months where sentiment shifted dramatically. For each, identify the likely cause based on review content.
Present all findings chronologically with specific date ranges, counts, and percentages.
Prompt 7: Product Improvement Priorities

You are a product strategist. I have uploaded [NUMBER] reviews from [PLATFORM] for [PRODUCT/COMPANY NAME].
Analyze all reviews and produce a prioritized product improvement roadmap:
1. CATEGORY MAP
Group all feedback into 6-8 product categories (e.g., Build Quality, Ease of Use, Customer Support, Price/Value, Performance, Documentation, Packaging, Compatibility). For each category, count the total mentions (both positive and negative).
2. SATISFACTION SCORE PER CATEGORY
For each category, calculate the ratio of positive to negative mentions. Rate as:
- High Satisfaction (>75% positive)
- Medium Satisfaction (50-75% positive)
- Low Satisfaction (<50% positive)
3. IMPROVEMENT OPPORTUNITIES
For each Medium and Low satisfaction category, list specific improvements based on customer feedback. Each improvement should be concrete and actionable -- not "make it better" but "add USB-C charging port (requested by 23% of reviewers)."
4. IMPACT vs EFFORT MATRIX
Classify each improvement as:
- Quick Win: high customer impact, likely low implementation effort
- Strategic Investment: high customer impact, likely significant effort
- Fill-In: lower customer impact, low effort
- Deprioritize: lower customer impact, high effort
5. RECOMMENDED ROADMAP
List the top 8 improvements in the order they should be tackled. For each, provide:
- The improvement
- Why it is prioritized at this position
- Expected customer impact (based on review frequency and severity)
- Supporting quotes from reviews
Ground every recommendation in specific review data. No speculation.
Prompt 8: Marketing Language Extraction
Use case: Mine the exact words and phrases customers use to describe their problems, outcomes, and experiences. This is raw material for ad copy, landing pages, email sequences, and social media content -- language that resonates because it comes from the audience itself.
You are a copywriting researcher. I have uploaded [NUMBER] reviews from [PLATFORM] for [PRODUCT/COMPANY NAME].
Mine these reviews for customer language that can be used in marketing materials. Extract verbatim phrases -- do not paraphrase or clean them up.

Prompt 9: Verified vs. Unverified Review Comparison
Use case: Determine whether verified and unverified reviews tell different stories. Useful for detecting review manipulation, understanding bias, and deciding how much weight to give different review segments. Works best with Amazon reviews where verification status is included in the export.
You are a review quality analyst. I have uploaded [NUMBER] reviews from [PLATFORM] for [PRODUCT/COMPANY NAME]. The data includes a verified purchase indicator.
Compare verified and unverified reviews across every dimension:
1. VOLUME SPLIT
How many reviews are verified vs. unverified? What percentage of total?
2. RATING COMPARISON
What is the average star rating for verified reviews vs. unverified reviews? Show the full distribution (1-5 stars) for each group.
3. SENTIMENT COMPARISON
Is sentiment more positive, negative, or neutral in one group vs. the other? Quantify the difference.
4. TOPIC DIFFERENCES
What do verified reviewers talk about that unverified reviewers do not, and vice versa? Are there themes unique to each group?
5. LANGUAGE QUALITY
Compare the average review length, specificity, and detail level between groups. Do verified reviews tend to include more product-specific details?
6. SUSPICIOUS PATTERNS
Flag any signs of review manipulation in either group:

Claude vs. ChatGPT for Review Analysis
Both Claude and ChatGPT are capable review analysis tools. If you have read our ChatGPT review analysis guide, you already know ChatGPT's strengths. Here is an honest comparison to help you choose the right tool -- or use both strategically.
| Dimension | Claude | ChatGPT |
|---|
| Context window | 200K tokens (~5,000+ reviews) | 128K tokens (~1,000-2,000 reviews) |
| File upload | CSV, PDF, text (free and Pro) | CSV, PDF, text (Plus only) |
| Persistent context | Projects feature (Pro) | GPTs / Custom instructions |
| CSV parsing accuracy | Excellent -- strong column awareness | Good -- occasional column confusion on large files |
| Instruction following | Very precise -- follows complex formats | Good -- sometimes deviates from structure |
| Categorization | Excellent -- consistent, no duplicates | Good -- may create overlapping categories |
| Hallucination risk | Lower -- sticks closer to source data | Moderate -- sometimes infers beyond data |
| Visual output | Artifacts (tables, charts, docs) | Code Interpreter (charts, graphs) |
| Free tier | Claude 3.5 Sonnet, limited usage | GPT-4o mini, limited usage |
| Paid plan | $20/month (Pro) | $20/month (Plus) |
| Best for | Large datasets, structured analysis, categorization, nuanced long-form output | Quick analysis, data visualization with Code Interpreter, conversational follow-ups |
When to use Claude: You have a large dataset (1,000+ reviews), you need precise categorization, you want structured output that follows your exact format, or you are doing ongoing analysis with the Projects feature.
When to use ChatGPT: You need quick visualizations through Code Interpreter, you are working with smaller datasets, or you prefer a more conversational analysis style.
When to use both: For high-stakes analyses -- competitive positioning, product launch decisions, major strategy pivots -- running the same prompt through both Claude and ChatGPT and comparing outputs produces the strongest results. Areas where both tools agree are high-confidence findings. Areas where they diverge are worth investigating further.
Advanced Techniques
Once you are comfortable with the basic export-upload-prompt workflow, these advanced techniques will deepen your analysis.
Projects for Ongoing Monitoring
Instead of running one-off analyses, set up a Claude Project for continuous review monitoring. Pin your latest review export to the project. Each week or month, export fresh reviews with Comment Exporter, update the pinned file, and run your standard prompts. Over time, you build a longitudinal view of customer sentiment that tracks the impact of product changes, marketing campaigns, and competitive moves.
Create separate projects for different analysis contexts: "Product A Customer Feedback," "Competitor Tracking," "Content Ideas from Reviews." Each project maintains its own pinned files and instructions, keeping your analyses organized and persistent.
Combining Reviews from Multiple Platforms
The most powerful insights come from cross-platform analysis. Export reviews from Amazon, comments from Reddit, and feedback from Etsy for the same product or brand. Upload all three CSV files to Claude in a single conversation.
Cross-platform analysis reveals which findings are universally true (a complaint appearing on Amazon, Reddit, and Etsy is a confirmed issue) versus platform-specific (Reddit users may surface technical issues that Amazon reviewers never mention). Claude's large context window makes this feasible -- three files of 1,500 reviews each still fits comfortably within the 200K token limit.
"I exported 2,000 Reddit comments and loaded them straight into my research pipeline." -- Pendo Kessam
Using Artifacts for Visual Reports
Claude's Artifacts feature generates structured visual elements inline. When you include instructions like "present this as a table" or "create a comparison chart," Claude produces formatted artifacts that you can:
- ✓Copy directly into Google Docs, Notion, or presentation tools.
- ✓Export as standalone documents.
- ✓Reference in follow-up conversations within the same project.
For review analysis, ask Claude to generate artifacts for sentiment breakdown tables, competitive comparison matrices, trend charts, and executive summary documents. These artifacts make it easy to share findings with team members who do not have Claude access.
Iterative Deep-Dive Analysis
Claude's conversation memory and large context window enable a powerful iterative workflow. Start broad, then drill deep:
- ✓Run the Sentiment Overview prompt (Prompt 1) to get the landscape.
- ✓Identify the most interesting finding -- say, 28% of reviews mention shipping problems.
- ✓Follow up: "Show me all reviews that mention shipping issues. Group them by specific complaint type."
- ✓Drill deeper: "For the 'delayed delivery' complaints, is there a pattern by month? Did these spike after a specific date?"
- ✓Extract action items: "Based on the shipping analysis, write a brief for the operations team with specific recommendations."
Each follow-up builds on the previous analysis. Claude maintains full context of both the original data and all prior conversation turns, so you never lose information as you drill deeper. This iterative approach often surfaces insights that a single prompt would miss.
Tips for Better Results with Claude
These tips come from extensive testing of review analysis workflows in Claude. Apply them to get consistently better output from every prompt.
- ✓Be specific about output format. Claude follows formatting instructions precisely. If you want a numbered list, say so. If you want a table with specific columns, define them. If you want bullet points under each heading, specify that. The more explicit your format requirements, the more usable Claude's output will be.
- ✓Provide context about your product and industry. Add a sentence like "This is a mid-range Bluetooth speaker competing with JBL and Bose" or "We are a B2B SaaS tool for project management." Context helps Claude interpret ambiguous review language correctly and produce more relevant categorizations.
- ✓Ask for structured output with headers. Prompts that request structured sections (numbered lists, named headers, tables) produce more actionable output than open-ended prompts. Compare "analyze these reviews" with the structured prompts in this guide -- the difference in output quality is dramatic.
- ✓Use Claude's follow-up capability. Do not try to extract everything in one prompt. Run a broad analysis first, then ask follow-up questions to drill into specific findings. Claude maintains the full conversation context, so follow-ups are seamless.
- ✓Request direct quotes. Always include "provide verbatim quotes from the reviews" in your prompts. Quotes ground the analysis in actual data and prevent Claude from generalizing or inventing patterns.
- ✓Pre-filter for sharper insights. Analyzing 1-2 star reviews separately from 4-5 star reviews produces sharper findings than dumping everything together. Use Excel or Google Sheets to filter before uploading, or ask Claude to segment the data: "Analyze only the reviews with 1-2 star ratings."
- ✓Leverage the Projects feature for repeated analysis. If you analyze reviews regularly -- weekly competitor monitoring, monthly customer feedback reviews -- set up a Claude Project. Pin your standing instructions and update the data file as needed. This saves time and ensures consistency across analyses.
Frequently Asked Questions
How many reviews can Claude analyze at once?
Claude's 200K token context window can handle approximately 5,000 or more reviews in a single upload, depending on average review length. Short reviews (1-2 sentences) allow for higher counts; longer, detailed reviews reduce the maximum. This is significantly more than most other AI tools, which start struggling above 1,000 reviews. For datasets exceeding 5,000 reviews, you can split them into two uploads or pre-filter in Google Sheets to focus on the most relevant subset. Claude Pro users can also use Projects to maintain context across multiple conversations with the same data.
Do I need Claude Pro to analyze review files?
No. Claude's free tier supports file uploads and provides access to Claude 3.5 Sonnet, which is fully capable of review analysis. The limitation is usage -- free-tier users have a daily cap on messages, which may restrict how many analysis prompts you can run in a single day. Claude Pro ($20/month) gives you significantly higher usage limits, access to Claude Opus 4 for more nuanced analysis, and the Projects feature for pinning data files across conversations. If you plan to analyze reviews regularly, Pro is worth the investment.
What file formats can I upload to Claude for review analysis?
Claude supports CSV, PDF, and plain text file uploads. For review analysis, CSV is the recommended format because it preserves structured columns -- review text, star ratings, dates, verification status, and other metadata -- that Claude can parse and reference throughout the analysis. Comment Exporter exports directly to CSV, making the workflow seamless. You can also paste smaller datasets (under 100 reviews) directly into the chat window without uploading a file.
