Readability Improver

Honestly, very similar in mechanism — both target shorter sentences and simpler wording for easier reading, without losing meaning. Readability Improver frames it as improving clarity/structure generally; Simplification Tool frames it specifically around vocabulary simplicity for a general audience. Try either; expect comparable results.

No — it rewrites the text directly rather than scoring the original. If you want an actual numeric readability score, use a dedicated text-statistics tool first, then bring the flagged passages here to improve.

It's instructed not to lose the key meaning while simplifying — but for highly technical text, review the output to confirm important precision wasn't lost in the simplification.

Sentence Shortener's priority is pure conciseness (fewer words); this tool's priority is overall clarity (which may or may not result in a shorter text) via simpler words and better structure.
