A tiny local tool that clusters negative product reviews by root cause

I built a small browser-only tool for shop owners drowning in 1–2★ reviews.

Paste reviews → keyword clusters into shipping / quality / description mismatch / service / packaging / value-for-money → shows share + example sentences. You can hand-edit tags; CSV export. Data stays in the browser (no upload).

Free to try; paid plan is ¥29/mo (~$4) for batch import + custom keywords (WeChat pay + redeem code).

Built for Chinese ecommerce sellers first; curious if the clustering approach is useful for Amazon/Shopify folks too. Feedback welcome — especially missing dimensions.
