Pengenalan alat

Gambaran keseluruhan alat

Different formulas weight different things — Flesch-Kincaid leans on syllable counts, ARI and Coleman-Liau use character counts, Gunning Fog and SMOG penalize long words. Each gives a slightly different angle on the same draft. Showing all five plus their average makes it easy to spot when your writing is genuinely too dense versus when one formula is over-penalizing a niche style. Everything runs client-side; no draft is uploaded.

Which score should I trust?+

Look at the average. For most general writing the Flesch Reading Ease is the most intuitive — aim for 60-70 to reach the broad public. For technical writing, the average grade level is the more useful number.

Why do the scores disagree?+

Each formula weights different signals. SMOG penalizes 3+ syllable words heavily, ARI focuses on character counts. A draft full of short technical jargon (like 'SQL', 'API') confuses character-based formulas but Flesch-Kincaid handles it fine.

Is the syllable count exact?+

It's heuristic — like every browser-based readability tool — and accurate within a few percent for English text. Names, acronyms, and very unusual spellings can drift.

Does it work for non-English?+

The formulas were calibrated for English. Spanish, French, German, etc. will still produce numbers, but the grade-level mapping isn't valid. Use it for relative comparisons, not absolute claims.
