About Grammar Checker

Grammar Checker turns a short brief into usable copy. Catch grammar, spelling, punctuation and clarity issues with inline fixes. You control tone, length, language and the keywords that have to appear, so the output reads like your brand rather than a generic model.

Everything is analysed locally in your browser. Your text is never uploaded, which makes this safe to use on unpublished drafts, client work and anything under NDA.

Grammar Checker is included on Professional and above. Every run counts against your plan's credit allowance, and results are saved to your history so you can return to them or attach them to a client report.

Why teams use it

Stop paying for a single-purpose tool

Grammar Checker is one of 312 tools on the same account. One subscription replaces the handful of point solutions most AI teams end up stacking.

Get to the decision faster

The output is structured around what you will do next, not around what was easiest to measure. Less interpretation, fewer meetings.

Share results without a screenshot

Export to PDF or CSV, or send a link. Clients and colleagues see the same thing you do, formatted properly.

Works the same on every device

The full workspace — including tables and exports — works on a phone, a tablet and a 4K display without a separate app.
