The agentic code editor
The agentic code editor
that finishes the job
Hand Cortex a task. It plans, reads your code, edits files, runs commands, and verifies its own work until the checks pass, all inside a real IDE.
Real agentic loop
DISCOVER → PLAN → ACT → VERIFY, with maker/checker separation and git checkpoints.
Bring your own key
Claude, GPT, Gemini, DeepSeek, Qwen, MiMo, Mistral, OpenRouter and more. Keys stay encrypted on your machine.
Private by design
Your code goes only to the model provider you choose, never through our servers.
250+ built-in skills
Office docs, TDD, browser testing and more, loaded on demand. MCP servers plug straight in.
Reviewable diffs
Every write is shown as a diff, and permission gates stop destructive commands before they run.
Native and fast
PyQt6 shell, Monaco editor, xterm.js terminal, project memory, and 16+ accessible themes.
