Is Grammarly safe to use?
Grammarly is safe for most everyday writing: it has one of the largest public records in the category — 35,000,000 users, a 4.5 rating across 43.1K reviews, and current updates. It is still a cloud writing service with broad page access, so keep it away from confidential drafts and use Chrome's site-access controls where needed.
Page access Broad
Requests page-content access across sites. Broad access is not itself a red flag — the question is whether the job justifies the reach, and whether the publisher's record earns it.
A cross-site writing assistant needs broad page access to offer inline feedback. Use Chrome’s site-access controls when the extension is not needed.
Store-disclosed data
- Personally identifiable information
- Personal communications
- Location
- User activity
- Website content
The store lists personally identifiable information, personal communications, location, user activity, and website content among handled categories. Consult Grammarly’s current privacy documentation for controls and exclusions.
Does Grammarly read everything I type?
On pages where it is enabled, yes — inline feedback requires reading the text field you are writing in, and the store disclosure lists website content and personal communications among handled data. Chrome's site-access controls let you switch it off for sensitive sites.
What data does Grammarly's store listing disclose?
Five categories: personally identifiable information, personal communications, location, user activity, and website content. That is the broadest disclosure among the proofreading tools we cover, and the reason we point confidential work elsewhere.
Is Grammarly free?
The core proofreading tier is free. Tone rewrites, fuller clarity suggestions, and the generative features sit in the paid Pro and enterprise plans.
