Key takeaways
- Rephrasy debuted in HumanizerBench in November 2026 and finished 16th of 16 with a composite score of 52.50.
- Its 73.9% detector pass rate was third-best of 16, but it kept less of the original meaning than any other tool and lost 11 penalty points, 10 of them for meaning drift.
- Plans cost $18.99 to $39 a month on monthly billing, or $99 to $220 a year on yearly billing, with a $14.99 24-hour pass and a $249 lifetime deal.
- The free plan covers up to 100 words, and refunds are case by case, with none for used credits or lifetime deals.
- Rephrasy's homepage promises 100% pass rates on every major detector, but its terms of service say it does not guarantee undetectable text.
Rephrasy makes some of the boldest promises in the AI humanizer category. Its homepage says the tool guarantees "100% pass rates" on every major AI detector, keeps your meaning intact, and delivers writing with zero grammatical errors. In November 2026, Rephrasy went through HumanizerBench, the public monthly benchmark the WriteHuman team runs, for the first time. The results back up one part of that pitch and contradict another.
This review covers what Rephrasy does, what it costs in November 2026, what its terms actually promise, and how it scored when six AI detectors checked its rewrites.
What Rephrasy is
Rephrasy is a web-based AI humanizer with a built-in AI detector. You paste text from ChatGPT, Claude, Gemini, or another model, pick a humanizer model or writing style, and get back a rewritten version. If you are not happy with a result, you can re-humanize the same text for free.
Around that core, Rephrasy has built a long list of extras.
- Writing style cloning. Paid plans let you save between one and ten custom writing styles, so rewrites can follow your own voice instead of a stock style.
- Chrome extension and mobile apps. The extension works inside Google Docs, Gmail, and LinkedIn, and there are apps for iOS and Android.
- API and MCP server. The Business and Professional plans include API access, and Rephrasy also offers an MCP server for connecting it to AI assistants.
- More than 50 languages. Rephrasy says English, German, Spanish, French, and Portuguese give the best results.
- Side tools. The site also sells a plagiarism checker and offers free utilities like a readability checker and an image upscaler, along with watermark removal tools.
The company behind the product is harder to pin down. Rephrasy's terms are governed by German law and list a German VAT number, but the provider address belongs to a third-party address service, and no company name, founder, or team appears anywhere on the site.
Rephrasy pricing in 2026
Rephrasy sells three subscriptions, a 24-hour pass, and a lifetime deal. The prices below come from the pricing section of Rephrasy's homepage in November 2026.
| Plan | Monthly billing | Yearly billing | Humanizations |
|---|---|---|---|
| Growth | $18.99/month | $99/year ($8.25/month) | 100 a month, up to 2,000 words each |
| Business | $25/month | $120/year ($10/month) | 200 a month, up to 2,000 words each |
| Professional | $39/month | $220/year ($18.33/month) | 400 a month, up to 2,000 words each |
| Quick Pass | $14.99 one time | Not offered | Unlimited for 24 hours |
| Lifetime Access | $249 one time | Not offered | Unlimited |
A few things stand out.
- Yearly billing is far cheaper. Growth costs $227.88 over a year on monthly billing and $99 on yearly billing, which is why Rephrasy advertises savings of up to 60%.
- Allowances are counted in runs, not words. Rephrasy describes Growth as 200,000 words a month, but that math assumes every one of your 100 humanizations uses the full 2,000 words.
- API access starts at Business. Access to the AI detector API only comes with Professional.
- The free plan is small. Rephrasy's FAQ says free users can humanize up to 100 words, and the AI detector is free to use.
The refund policy and the fine print
Rephrasy's terms say refunds are possible only under certain conditions. Used credits are never refunded, lifetime deals are never refunded, and everything else is decided case by case. The terms also say Rephrasy does not refund simply on request and point users to the free trial instead. With a free plan that tops out at 100 words, that is a thin way to judge a tool before paying.
If you cancel a subscription, your humanizer limit drops back to 100 words, though any unused credits stay on your account.
The biggest gap is between the homepage and the contract. The FAQ promises 100% pass rates on every major detector. The terms of service say Rephrasy does not guarantee that humanized text will be undetectable by AI detectors. When the marketing and the legal page disagree, the legal page is the one that counts.
How Rephrasy scored in HumanizerBench
November 2026 was Rephrasy's first HumanizerBench cycle. Each of the 16 tools rewrote the same 30 samples, and six AI detectors checked every rewrite. Those were GPTZero, Copyleaks, ZeroGPT, Winston AI, Pangram, and Originality.ai. The composite score also measures how well each rewrite keeps the original meaning, how readable it is, and how consistent the tool is, then subtracts penalty points for rewrites that drift from the original or change length too much.
Rephrasy finished 16th of 16 with a composite score of 52.50. The ranking alone hides what actually happened, though.
| Detector | Rephrasy | WriteHuman |
|---|---|---|
| GPTZero | 96.2% | 99.9% |
| Copyleaks | 96.7% | 96.7% |
| Winston AI | 95.3% | 97.2% |
| ZeroGPT | 75.8% | 87.3% |
| Pangram | 48.4% | 68.9% |
| Originality.ai | 31.0% | 36.5% |
| Overall detector pass rate | 73.9% | 81.1% |
On detection alone, Rephrasy did well. Its 73.9% detector pass rate was third-best on the board, behind only Phrasly and WriteHuman. It also held up better than most tools against Pangram, one of the two strictest detectors in the test, which rated 14 of its 30 texts as human.
The problem was meaning. Rephrasy kept less of the original meaning than any other tool on the board, and 10 of its rewrites drifted far enough from what they were given to cost it a penalty point each. With one more penalty point on top, it lost 11 points in total, the most of any tool this cycle.
Without penalties, Rephrasy would have scored about 63.5, enough for seventh place. Meaning drift is what dropped it to last.
That trade-off matters in practice. A rewrite that gets past a detector but no longer says what you meant is not a usable rewrite, and fixing it by hand eats the time the tool was supposed to save.
HumanizerBench's Rephrasy vs WriteHuman comparison also breaks the results down by type of writing. Rephrasy came closest on discussion board posts, scoring 66.1 against WriteHuman's 70.9, and fell furthest behind on blog posts, scoring 40.6 against 66.7.
Who Rephrasy fits
Rephrasy makes the most sense for someone who cares mainly about detector scores on short, informal text and is willing to read every rewrite closely before using it. The free re-humanize button helps when a rewrite misses, and style cloning is a genuinely useful feature that many humanizers lack. The low yearly prices and the Chrome extension also make it easy to fit into a daily routine.
It is a weaker fit for anyone whose writing has to stay accurate, like client work, product copy, reports, or anything with facts and figures that cannot change. Its benchmark results show more meaning drift than any other tool tested, and its refund terms make that an expensive thing to discover after paying.
The verdict on Rephrasy
Rephrasy is a feature-rich humanizer with strong detector numbers and a serious accuracy problem. In November it got more of its text past detectors than 13 of the 15 other tools, which is a real result. It also changed what the text said more than any of them, enough to finish last once penalties were counted. Add a contract that disclaims the guarantee its homepage makes, a 100-word free plan, and a strict refund policy, and the safest approach is to test it carefully before committing to a plan.
If you want a tool that does well on both detection and meaning, WriteHuman finished first of 16 in the same cycle with a 70.11 composite score, an 81.1% detector pass rate, and a single penalty point. The fairest test is still your own. Run the same paragraph through both tools, read each rewrite line by line to see whether it still says what you meant, and check both with more than one AI detector, since detectors often disagree. You can try WriteHuman free, and our guide to the best AI humanizers of 2026 covers the rest of the field.
