CoCalc

What is CoCalc?

CoCalc is a platform where users describe a software task and an AI agent builds it within a project containing their files and installed tools. It supports the integrated Codex agent, Claude Code, or other command-line agents running in project terminals. Claude Code availability depends on site configuration and requires a CoCalc membership, a Claude Pro or Max subscription, or an Anthropic API key.

What are the features of CoCalc?

• AI code generation

  Users describe a desired outcome and point the agent at project files; the agent works using the software already installed in that project.
• Side-by-side review

  Generated applications, reports, or charts open beside the conversation so users can inspect results and ask the agent to explain its actions.
• Iterative refinement

  Users can request alternative versions from the agent or open files, notebooks, and terminals to continue editing manually.
• Multiple agent support

  The platform runs an integrated Codex agent, Claude Code where enabled, or other command-line agents directly in project terminals.
• Live collaboration

  Project collaborators see edits made by the agent or other users in real time.
• Version restoration

  Users can restore earlier versions of their project files.

What are the use cases of CoCalc?

• Application building

  A user describes an application idea and the agent generates the working app within the existing project environment.
• Data analysis

  A user directs the agent to project files to produce a report or chart based on the available data.

How to use CoCalc?

1. Describe the outcome

   State what you want and point the agent at your project files via the web interface.
2. Review the result

   Open the generated app, report, or chart beside the conversation and ask the agent what it did.
3. Refine or take over

   Request another version from the agent, or open the files, notebooks, and terminals to continue work yourself.
