SpyLogger was a Telegram bot that told you when someone edited or deleted a message in your private chats, and what it said: text, photos, videos, video notes, voice messages and files. It plugged in as a Telegram Business chatbot, with no second account and nothing to install, and ran on paid subscriptions from December 2024 to June 2026.

I founded it and wrote all of its software: a Python bot on aiogram and asyncio that kept a copy of every message in Redis, diffed the edit or restored the deletion, and sent the notice at once. Subscriptions were sold in Telegram Stars with a seven-day trial and referral rewards, in Russian and English; 5,000 users connected it before I archived it in June 2026.
