Cortex AI IDE

Cortex is a native agentic AI code editor for Windows and Linux that understands your whole project. Its agent runs a Discover → Plan → Act → Verify loop with maker/checker separation, edits across multiple files, runs terminal commands, and shows reviewable diffs before anything is merged. Bring your own key for Claude, GPT, Gemini, DeepSeek, Qwen, MiMo and more — your code never touches our servers. Ships with 250+ built-in skills for debugging, refactoring and testing, semantic codebase search, and local project memory. Free and open source, with an optional subscription for hosted search, web tools and voice input.
