SEO DESK
Count sentences, words, and syllables (a heuristic English-syllable counter) to compute the Flesch reading-ease score. Higher values are easier; this is one heuristic, not a language model.
WHAT THIS DOES
Runs entirely in your browser.
/tools/readability-checkerreadability-checkerv4.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.

BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of text and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
Score = 206.835 − 1.015 × (words / sentences) − 84.6 × (syllables / words). Syllables are counted by a vowel-cluster heuristic.
Boundary: English heuristic. Non-English and highly technical text will produce unreliable scores.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. The Flesch readability checker runs entirely in the browser.
No. These are local helpers for common artifacts. Production SEO still requires analytics, search-console data, and human review.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Text are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: Text (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
English heuristic. Non-English and highly technical text will produce unreliable scores.
