The Problem

AI coding assistants like Claude Code and Aider are incredible — but they're either:

  • Expensive (Claude Code: $20-200/month)
  • Locked to one provider (Claude Code → Anthropic only)
  • Heavy (Node.js, lots of dependencies)
  • No free tier for local/offline use

I wanted something that:

  • Works with any AI provider
  • Has a free tier (Gemini, Groq, Ollama)
  • Runs in the terminal with a beautiful UI
  • Is truly open source

What Is TermMind?

TermMind is a modern, open-source AI terminal assistant. Think Claude Code or Aider — but free, open-source, and lightweight.

pip install termmind
termmind init    # Select provider & API key
termmind chat    # Start chatting with AI
Enter fullscreen mode Exit fullscreen mode

Supported Providers (7!)

Provider Free Tier? Setup
Google Gemini ✅ Yes (free API key) aistudio.google.com
Groq ✅ Yes (free tier) console.groq.com
