ReviewMiner

Collect Amazon reviews. Multi-product, auto-expand, smart dedup, rating distribution. Export CSV/Markdown/Excel. 100% local.

ReviewMiner is a browser extension focused on collecting Amazon review data — turning scattered review pages into clean, structured files for analysis, product research, and customer-feedback mining. Core features: • Multi-product & multi-batch — track many products at once; collect each by star rating or time, never mixed up. • One-click auto-collect — scrolls and expands reviews automatically (up to ~100 per star rating). No manual copy-paste. • Smart dedup — deduplicates by user + rating + date + title; merges across batches and updates helpful votes. • Rating distribution — captures the product's 1–5 star percentages and average, written into exports. • Three formats — exports CSV, Markdown, and Excel simultaneously, with product info and distribution columns. • Local persistence — data stays in your browser; clear it anytime. Privacy first: • No network calls, no uploads, no personal data collected. • All review data stays on your device, in your browser. • No account, no login, no tracking, no ads. Currently supports English Amazon sites: US / UK / CA / AU / IN. Other languages (DE/FR/JP, etc.) coming in Pro.
