WATag — one-click archive for WhatsApp Web

Flags promotional chats on WhatsApp Web, with one-click Archive. Changes sync to your phone automatically.

WhatsApp Web's chat list gets buried in "50% off!" promo spam from banks, delivery apps, and mailing lists. WATag flags those chats automatically and gives you a one-click Archive button — no need to open each one. **Features** - Smart detection — flags chats matching keywords from any of your categories - Custom categories — group keywords into your own categories, each with its own name and badge color - One-click Archive — archive promotional chats without opening them - False positive handling — mark a chat "Not an ad" and it's never flagged again - Archive counter — track how many chats you've cleaned up - Phone sync — archives sync automatically to your mobile WhatsApp, since it's the same account **How it works** WATag runs entirely in your browser. It reads the visible chat list on web.whatsapp.com, matches chat names/previews against keywords you configure, and adds a small badge with Archive / Not-an-ad buttons. All settings are stored locally — there's no backend server and nothing is ever sent off your device. **Limitations, honestly** WhatsApp doesn't run ads in normal chats — this flags things that *look* promotional based on keyword matches, so tune your categories to your own inbox. WhatsApp Web's page structure isn't public and can change; if a redesign breaks the one-click action, WATag opens the right menu and asks you to finish with one manual click until it's updated.
