An AI email assistant that drafts, summarizes, and perfects your messages in place
Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.

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.
