Dertet Harness is a free, open-source AI workspace for Windows (plus Android/iOS chat clients). Bring your own key for OpenAI, Anthropic, Gemini, OpenRouter, or run a local model via Ollama/LM Studio. The built-in agent isn't just a chatbot: it edits code, runs commands, browses the web in its own tab, can control your screen, and edits video with ffmpeg. Slash commands, persistent memory, 9 languages. No subscription.

Hey Product Hunt 👋 I built Dertet Harness because I wanted one app that does both things well: chat with any AI model, and actually get work done on my PC — not a thin wrapper around an API, but an agent that reads my files, runs commands, browses a page when it needs to, and fixes a bug end-to-end without me babysitting every step. It's free and open source. Bring your own API key for whichever provider you like (OpenAI, Anthropic, Gemini, OpenRouter, and more), or skip the cloud entirely and point it at a local model via Ollama/LM Studio. There are also Android/iOS companion apps for quick chats on the go. Still actively building this solo, so I'd genuinely love your feedback — and I'll be here answering questions all day.
