Doco
AI Agent for Microsoft Word
Visit website →About
Doco is an AI writing assistant built natively into Microsoft Word, aimed at structured document work. It combines the roles of a grammar checker, an editing agent, and a copilot in one sidebar, tuned for long, formatted documents rather than short text.
It can reference other files as context, and users can set up custom projects and reusable workflows, all without leaving Word.
It is aimed at people who produce serious documents in Word, contracts, reports, proposals, research, and want an assistant that understands document structure and can pull in related material, rather than a generic chat window in another tab.

Why we picked it
Doco earns its place for being native inside Word rather than a separate writing app — grammar checking, editing, and copiloting live in one sidebar tuned for long formatted documents, not short chat-style text.
