You can bulk-leave Telegram groups without touching the API

If you're drowning in Telegram groups, there are actually a few ways to clean up:

1. Manual (painful): Settings → each group → Leave. One at a time.

2. Telegram desktop: slightly faster but still one at a time.

3. Third-party tools: most require you to set up a developer account and generate API keys. If you're not technical, this is a wall.

4. TG Cleaner (what I built): log in with phone number, see everything, bulk select and leave. No API keys.

I built option 4 because option 3 frustrated me. Free tier is 10 leaves/month.

Happy to answer questions about how it works — using Telegram's official MTProto protocol so sessions are safe.
