grpsignal Telegram Monitor by Ralex48

Monitor selected Telegram Web groups locally with optional Helper sync and user-controlled alerts.

About this extension

grpsignal Telegram Monitor helps you monitor Telegram Web groups you choose in your own browser. Add keywords, keep Telegram Web open, and the extension watches for useful matches locally.

The extension is local-first: monitored Telegram content is processed in the browser and is not uploaded to grpsignal by default. Workspace Helper support adds local saved history, reports, diagnostics, required access activation. Optional bot alerts can send matched alert text through the grpsignal relay and Telegram only after you connect the bot.

grpsignal is not an official Telegram, Mozilla, Firefox, Chrome, or browser product, and is not partnered with those services.
