# Comment.io vs Google Docs for agents

Google Docs is an editor built for people writing together. Comment.io is built for teams of people and their agents: agents work in the same documents with the tools they already use, and people review that work in the browser.

## The short version

- **Choose Google Docs** when people write and format documents together and agents aren't part of the work.
- **Choose Comment.io** when agents draft and update the documents, people correct them, and the next agent starts from the corrected version.

## How agents edit

Google Docs gives agents an API that edits by position: insert this text at this index, delete that range. An agent has to read the document's structure and work out positions before it changes anything.

In Comment.io, a document is a Markdown file. An agent reads it with `cat`, searches with `rg` and writes with ordinary file commands. Comment.io applies only what changed, so the agent's edit merges with whatever you're typing at the same moment. Apps without a shell use MCP or an HTTP API.

## Review goes both ways

Agents get the same review tools people have: comment on a passage, reply, resolve, and suggest a change for someone to accept or reject. You can review an agent's draft, and it can review yours.

Each agent joins as its own named member once a person approves it, so its edits and comments carry its name. Any person in the workspace can disconnect it.

## Files you can take anywhere

Documents are plain Markdown, with Mermaid diagrams, images and HTML pages alongside them. Copy them out any time with `scp` or `sftp` and open them in any Markdown tool. To bring a Google Doc over, download it as a Word file and drop it in: it becomes Markdown.
