Frequently Asked Questions

Is my data private?

Yes. Everything runs in your browser. Your review data never leaves your device and is not uploaded to any server. We do not collect or store any of your data.

What file formats are supported?

We support CSV and Excel files (XLSX and XLS). Your file should have columns for rating, review text, and optionally date, title, author, verified status, and product variant.

How does theme extraction work?

We use keyword and n-gram analysis to identify recurring phrases in your reviews. This is completely deterministic and does not use any AI or LLM. The themes are extracted from the actual text in your reviews.

Can it handle large files?

Yes. The tool is optimized to handle files with 10,000+ reviews smoothly. Processing happens efficiently in your browser.

Do I need to sign up?

No signup required. The tool is completely free and works immediately in your browser.

Where can I get reviews from?

You can use reviews from any source. If you need to export reviews from Google Maps, Amazon, or Trustpilot, check out our Chrome extensions above. For Trustpilot, Shopify, and Google Play at larger scale, use the Apify Actors on the Review Data hub. You can also use reviews from your own systems, surveys, or any other platform that can export to CSV or Excel.
