Telegram Translation Bot with integrated local AI

A Telegram bot that translates messages using a locally running LLM (Ollama), so no data leaving your machine.

Example:

• Input: Hello, how are you?
• Output: Привет, как дела?

How translation works

• Language is detected using langdetect
• Target language is selected via simple rules (you can easily customise it however you like):
  • EN / DE -> Russian
  • RU -> English
• A prompt is sent to the local LLM
• The model returns only the translated text
