Frequently asked questions
Are my reviews uploaded to your servers?
No. Reviews are analyzed entirely inside your browser with a keyword classifier. They never leave your device — you can verify this in your browser's network panel.
How accurate is the automatic classification?
It is a keyword-based heuristic, not AI: reviews that clearly mention shipping, quality, refunds and similar signals are classified reliably, but sarcasm and vague complaints can be missed. Every review can be re-classified with one click, and the summary and CSV update instantly. For important decisions, skim the "Other / unclear" group manually.
What review sources can I paste in?
Any text: Amazon, Etsy, Shopify or app-store reviews work — one per line, a .txt file, or a .csv export (the tool picks the longest text column automatically).
Is there a limit?
The free version analyzes up to 2,000 reviews per run. Review Analyzer Pro ($29 one-time) removes the limit and adds custom categories, competitor comparison and trend tracking.
