About Readability Checker
Readability Checker is a SEO tool built for people who have to show results, not just activity. Score content with Flesch, Gunning Fog and grade-level readability metrics. Instead of a wall of raw numbers, you get a 0–100 score with a breakdown that points directly at what to change next.
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 Your text is never uploaded, which makes this safe to use on unpublished drafts, client work and anything under NDA.
Readability 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
Readability Checker is one of 312 tools on the same account. One subscription replaces the handful of point solutions most SEO 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.
