This service rewrites text produced by a language model so that it reads as if a person wrote it, and so that it is scored as human by AI detection tools. Text is pasted in or uploaded as a file, a rewrite mode is chosen, and the result can be run through again or rephrased selectively until it reads the way the writer wants. Around that core the site packages a paraphrasing tool, a plagiarism checker, a grammar checker with a fix all errors action, a readability checker, an essay writer and a built in AI detector for checking the result before it leaves the page. Plans are metered by words, counted separately for humanizing and for paraphrasing, while the checkers are unlimited on every paid tier. Three plans are published, with yearly billing advertised at half the monthly rate. Lite costs $4.99 per month and covers 5,000 humanizer words and 2,500 paraphraser words, with file uploads up to 5,000 words. Pro costs $12.49 per month for 25,000 humanizer words and 12,500 paraphraser words and adds priority email support. Unlimited costs $29.99 per month, removes the word caps and the file size cap, and adds first access to new features. Buyers should weigh one thing carefully. The product is marketed on its ability to defeat AI detection, which puts it at odds with the academic integrity rules of most institutions and with the disclosure policies of many publishers and employers.
