Features
AI captures the nuance that Google Translate misses
Translation quality only possible with large language models
LLM-powered quality
Not Google Translate — a large language model understands context and delivers more natural, accurate translations.
Handles slang and casual speech
Everyday conversation, internet slang, abbreviations — AI understands it all and translates naturally.
Free and unlimited
No message limits, ever. We run AI on our own servers, so it stays free for you.
Set up in 1 minute
Just add the bot and invite it to your group. No complicated configuration needed.
