Paraphrase, proofread and summarize text with an AI writing workspace
Rewrite sentences and paragraphs in modes like Standard, Fluency, Formal, Simple, Creative and Shorten/Expand to match tone and length.
Scan your text for grammar, spelling, punctuation and clarity issues and apply suggested fixes.
Condense long documents or articles into key points, with adjustable length.
Generate citations in APA, MLA, Chicago and other styles from a URL, title or DOI.

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.
