Readability Score for Documentation
Paste markdown or a docs URL — get a clear readability score plus the standard Flesch-Kincaid Reading Ease and Grade Level, heading depth, sentence length, and acronym density. Then Gemini rewrites your worst-reading section so you can see what better looks like. Hemingway-style, but tuned for technical writing.
How it works
1
Input
URL or markdown — we strip code blocks, lists, and tags before analyzing prose.
2
Score
Flesch-Kincaid, structural breakdown, and a 0-100 docs-tuned composite.
3
Rewrite
Gemini 2.5 Flash Lite rewrites the worst section so you can see what better reads like.
