For Developers

Ship with a second brain.

Generate real projects, execute them in a sandbox, and debug with an assistant that holds your whole codebase context - from first scaffold to production fix.

Code that runs

BuilderAgent writes complete projects and executes them in an isolated sandbox, returning working results instead of snippets.

Context-aware debugging

Paste errors or upload files; project context and memory keep the assistant oriented in your architecture.

Artifacts for code

Generated code lives in a persistent canvas you can iterate on across sessions.
