Today we’re launching Mistle for macOS, our first public release. We built it to empower non-technical builders to learn and create with AI. It’s reimagined from the ground up, inspired by popular AI tools like Cursor, then reshaped for people who don’t write code every day. Mistle runs on GPT-5-Codex, the model we trust most for thoughtful code generation and step-by-step problem solving. We set ourselves a challenge: help non-coders understand and evaluate code without feeling overwhelmed. That led to three features designed for clarity:
  • Ask Your Codebase. Get detailed, easy-to-understand answers about the state of your project so you can explore features, trace bugs, or prep for the next task.
  • Ask In Chat. Learn as you build. Highlight any response and get it explained in plain English.
  • Review. Run a review to double-check the coding agent’s work. Mistle spots logic or quality issues and suggests actionable tasks to fix them.
Mistle for macOS is available today. We can’t wait to see what you build.
