We built Perspt (short for *Personal Spectrum Pertaining Thoughts*) while learning Rust. It quickly evolved from an experiment into a useful CLI tool to test various AI models and services quickly. We find it useful and thought it will be of some interest in this community.

  What you can do with Perspt:

   • Chat with any model (internally we use genai Crate): supports OpenAI, Anthropic, Gemini, Groq, Cohere, xAI, DeepSeek, Ollama, and more.
   • Streamed markdown responses in a responsive interface—scrollable, crash-safe, with intuitive keybindings (built using Ratatui).
   • Start instantly: Perspt auto-detects your LLM provider based on environment variables—no config or signup required.
   • Export conversations to share later with the /save command.
   • Includes in-depth docs and a “Perspt Book” explaining the UI architecture and Rust patterns.

We’d appreciate any feedback, feature ideas, or bug reports. Thanks for checking it out.
