Delimiter Readability Checker

What Delimiter Readability Checker is

Delimiter Readability Checker is a free web tool that scores text using Flesch Reading Ease, Flesch–Kincaid Grade, and Gunning Fog formulas. It shows sentence and syllable averages alongside the scores, and analysis updates automatically in the browser. Text entered into the checker is not sent to a server, and no account is required. A Load file control accepts text input, while a Copy control lets users copy the results. The page suggests the tool for reviewing public-facing copy, plain-English requirements, long articles, and draft rewrites. It also provides sentence analysis and clarity recommendations. The formulas were calibrated on English prose, so results for other languages are not meaningful. They measure sentence and word length rather than clarity, accuracy, or structure. Syllable counting is heuristic, so individual words may be counted incorrectly. The site lists [email protected] for contact, but says replies are not instant and makes no response-time commitment.

Who it suits

It suits writers who want quick formula-based readability scores for English text, including public-facing copy and long drafts. It is less suitable for judging writing quality beyond sentence and word length.

Limits

The formulas are calibrated for English, and their scores reflect sentence and word length rather than clarity, accuracy or structure. Syllable counts are heuristic and may be wrong for individual words.

Getting started

1. Open https://www.delimiter.live/tools/readability-checker in a web browser.
2. Enter text in the checker or use its Load file control.
3. Review the automatically updated scores, averages and recommendations.
4. Use Copy to copy the results.

Verdict

Delimiter Readability Checker offers local, account-free scoring for English prose. Treat its results as measures of sentence and word length, not a complete assessment of writing quality.
