The Bot
A free, open alternative to ChatGPT — with GPT-5, Claude 4, Gemini 2.5, Llama, and Groq in a single polished interface.
Bring your own API keys. Pay only for what you use.
Works with the models you already love
The Bot is intended to be drop-in familiar for ChatGPT users — and immediately better the moment you switch.
Use GPT-5, Claude 4, Gemini 2.5, Llama, and Groq side-by-side. Switch assistants mid-conversation without losing context.
Bring your own API keys and pay only for what you use. Skip the stack of overlapping monthly subscriptions.
You'll rarely hit "you've reached the current usage cap" errors. Work as much as you need to.
Full-text search across all of your conversations and providers. Share any thread with a single link.
Open in Safari and tap "Add to Home Screen" for a near-native experience on your phone. Dark mode included.
A Ruby on Rails app you can self-host on a server or run locally — your data stays where you put it.
The Bot is free. The only thing you pay for is the API usage from OpenAI, Anthropic, Google, or Groq — at provider cost, billed directly by them. Most people pay a few dollars a month instead of $20+ per service.
