Telegram alerts & reports

Send scan reports & sell-out alerts to Telegram

The extension doesn't use browser notifications — every message goes through Telegram (you'll get it even when Chrome is closed). After each scan: top 15 bestsellers per watched keyword, a sold/views/reviews/favorites update per watched listing, and an active/sales/reviews/favs update (with top sellers & newest listings) per watched shop — plus an instant alert the moment a listing sells out and renews.

Bestseller score (Composite Score)

Needs ≥2 scans a few days apart to compute a score — listings without enough data show "not enough data" instead of a misleading score.
