cortex.foundation. Cortex Chat answers questions and does research, Cortex Code works inside your repositories, Cortex Bot runs on a computer of its own, Cortex CLI drives Code from a terminal, Cortex Design holds canvases, and Cortex Security reviews pull requests where they already live. The same sign-in opens all of them.
This is the product documentation. It explains what each application does, what you can do without an account, what signing in adds, and where every control lives. Start with the card for the application you came here for, or take the quickstart if you have never opened Cortex at all.
Pick an application
Cortex Chat
Ask, research and create. Conversations, projects, Library, memory, tools, images and scheduled tasks. The only application that works before you sign in.
Cortex Code
Agents in your repositories. Sessions, isolated runtimes, approvals, changes, tickets and pull-request review. Not a chat with a different icon.
Cortex Bot
A teammate with a computer. A bot browses, clicks and works on a desktop you can watch, and parks consequential steps for your approval.
Cortex CLI
Cortex Code in the terminal. Install, sign in, run sessions, use local and remote hosts, script headless runs and wire it into continuous integration.
Cortex Design
Canvases hosted from Chat or Code and edited in the Cortex Design desktop app. Versions, a reusable library and export.
Cortex Security
Pull-request review without pasting a diff. The change stays in the repository and Cortex reads it there, then writes a check run and a summary.
Which one do I need?
For the long version, with what each one needs before it will open, read Which product do I need?.
Chat is never gated. Everything else is for signed-in accounts, and Cortex Code and Cortex Bot are in closed beta, so a signed-in account that has not been invited sees a dialog offering to continue in Chat. See Accounts and sign-in.

Two-factor authentication
Enrol an authenticator app, and the confirmation that export and deletion require.
