The purpose of an AI rewriter should not be limited to substituting a couple of words but rather to rewrite the sentence such that it sounds natural and isn’t identified as machine generated. This is how the top choices stack up.
1. Humanize AI Pro (Best Overall)
The Humanize AI Pro, as opposed to synonym substitution, restructures the sentences and vocabulary distribution; hence, it is the best at evading detection in the above list and happens to be 100% free with no word limit.
2. QuillBot
QuillBot is an excellent editor for grammar and phrasing; however, since QuillBot mostly substitutes synonyms, it will not escape the algorithms used by AI detection tools.
3. Wordtune
Wordtune is reliable for altering the tone in brief pieces of text, although the daily quota of rewritten content per day makes it unsuitable for larger texts.
4. Undetectable AI
An efficient paid rewriter that has a decent bypass ratio but offers only a small amount of words for its free trial.
5. HIX Bypass
HIX Bypass works well when used in "Balanced" mode, having an adequate amount of words per month which suits normal usage, and being priced similarly to Undetectable AI.
6. Jasper AI
Jasper has been designed mainly for content generation and not as a rewriter, and hence, it fails to perform well on the bypass performance test.
How to Choose the Right AI Rewriter
- If you need free and unlimited: There is only one such product on this list – Humanize AI Pro.
- If you're just editing your own work: Quillbot and Wordtune can be used for correcting grammar and improving tone but not for bypassing detection.
- If bypass rate matters most: use products designed for perplexity and burstiness adjustments.
