Document CoPilot is an AI assistant for collaborating on text directly inside Google Docs—no browser extensions or separate apps required.
How it works
Share your Google Doc with document.copilot@gmail.com like you would with any other collaborator. CoPilot joins your existing comment workflow and suggests edits, improvements, and ideas right in the Google Docs interface.
What it’s good for
Use it to refine long-form documents without changing your process, including:
- Product specs
- Student papers
- Investment memos
- Substack articles
- Book reviews
- Other long-form writing
It can help edit, rephrase, and improve structure and style while keeping your document workflow intact.
Privacy and control
Document CoPilot’s servers do not log document contents. You can revoke access at any time by removing it from the document’s sharing list, making it a practical option for everyday document editing and collaboration.
