What Cortex AI IDE is

Cortex AI IDE is a coding workspace that plans changes, edits across files, runs terminal commands, and checks results through reviewable diffs. Its agent tools include search, Git, LSP features, and task tracking, while more than 250 included skills cover work such as debugging, refactoring, documentation, SEO, and design reviews. Developers can use eight built-in AI provider integrations, connect OpenAI-compatible endpoints, or extend the IDE with MCP servers. Project memory and chat history are stored locally in each project. API keys are kept in the operating system’s secure credential store, and BYOK requests go directly to the selected provider over TLS. The free plan costs nothing and requires users to bring their own API keys, with model usage paid to providers. Pro Monthly is $10 a month; Pro Yearly is $80 a year. AI features require an internet connection and a supported API key. Native Windows and Linux builds are listed; macOS users are provided a source-build guide rather than a prebuilt installer.
