Apps and AI tools can now suggest edits in Google Docs instead of just making them, like an editor with a red pen

From 30 September, Google's Workspace APIs let apps leave comments in your files and, in Docs, submit changes as suggestions. Your tools can now ask before they edit.

Anyone who has let an automation loose on a shared document knows the feeling. You open the file and something has been 'helpfully' rewritten, with no clue what changed. On 30 September Google gave apps a politer option. The Google Docs, Sheets and Slides APIs can now work with comments, and the Docs API can submit proposed text changes as suggestions.

In Docs, that means a connected tool can put forward an edit the same way a colleague in suggesting mode does, and you accept or reject it. Sheets gets comments on specific cells, and Slides gets comments on individual slides and elements. Google's own examples include review workflows and third-party tools that propose edits rather than making direct changes. It's rolling out gradually from 30 September, with up to 15 days before everyone sees it, and it's available to all Workspace customers and personal Google accounts. Admins can still restrict which apps get access to your data.

For a midsize business, this is a change you won't notice until a tool you use takes advantage of it. Once your AI writing tools and automations start using it, they can leave notes and suggestions in your documents rather than overwriting them. It's the difference between a new starter who emails you questions and one who reorganises your filing cabinet over the weekend.

My advice: when your tools start offering this, choose suggest over edit. Anything going to a client, like a proposal or a contract, should get a human tick before the change lands. If you build your own automations in Zapier or Make, check whether they can use suggestions, and switch any 'just update the doc' steps on important files over to them. Keep direct edits for low-stakes stuff like internal notes.

It's a small API change with a sensible idea behind it. AI that asks before it edits is easier to trust, and much easier to check than whatever happened to paragraph three while you were at lunch.
