Browse this task →| Criterion | Scribbr Paragraph Rewriter & Paraphraser AI paraphrasing & rewriting 88/100 Seven-aspect task score Scribbr integrates QuillBot's neural paraphrasing engine for sign-up-free English rewriting, completing a 5-sentence restructuring in 4.8s. It achieved 71.6% lexical diversity with 100.0% fact retention (all 7 crucial figures, dates, and verification token) and up to 125 words per guest run with direct copy and export. Tested export TXT · Output attached Historical test · 2026-11-06 | Hemingway Editor AI paraphrasing & rewriting 65/100 Seven-aspect task score Hemingway Editor (Boondoggle Studio, LLC) is famed for color-coded readability grading and offers a free online AI paraphraser. In testing, its cloud API is fast (1.31s server wait) and produces fluent phrasing with one-click copying; however, the free tool imposes strict output truncation (cutting off mid-sentence at word 17), dropping key data points and tokens, positioning it primarily as a short-sentence teaser for Hemingway Editor Plus.
