Build and Use Software with AI | CoCalc

Describe what you want, and an agent builds it in a project with your files and software. Review the result beside the conversation, then refine it or take over yourself.

Use the integrated Codex agent, Claude Code on sites that enable it, or other command-line agents in project terminals, all with the files, tools, and running services your collaborators already use. Claude Code can use CoCalc membership, a Claude Pro or Max subscription, or an Anthropic API key, where the site offers them.
