Why I Built It

I wanted a private, fast way to chat with multiple AI models without switching between apps. Telegram is where I already spend time, so bringing GPT-4o, Claude, and Gemini into one bot made sense. OpenRouter gives access to all models through a single API, and streaming makes the experience feel instant.
