Write code with precision, hand bigger jobs to agents, and keep working from anywhere
Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.

AI pull request descriptions and refactoring for GitHub and GitLab
Every PR gets a written summary of what changed in plain English, giving reviewers context without digging through the patch.
Simplified, translated summaries go out via Slack, email, or webhooks to keep non-technical teammates in the loop.
Request improvements directly in a pull request comment and let the AI help draft the refactoring.
Aggregate a week of work into a single clear update so nobody has to chase progress manually.
