AI Humanizer
Paste an AI draft and get it back without stock phrases, padded transitions and same-length sentences. Numbers, names, links and longer quotes are checked against your original. Meaning isn't, so read the result before you use it.
It is an editing tool, not a way around academic integrity checks, and it does not promise to beat any detector.
Edits your text in its current form: same purpose, audience and formality.
What are they?
This replaces or removes these characters: em and en dashes, curly quotes, the ellipsis character, bullet characters, special spaces and hidden characters such as zero-width spaces.
With this on, the rewrite gets plain equivalents instead (a spaced hyphen, straight quotes, three dots, a normal space), and hidden characters are removed.
These are kept: the Persian zero-width non-joiner, emoji joiners, French guillemets, and Chinese or Japanese punctuation. French spacing stays: the space before a semicolon, colon, exclamation mark, question mark or closing guillemet, the space after an opening guillemet, and the space between groups of digits. In a text that opens quotations with „, every curly quotation mark stays as it is. Nothing inside code, tables, quoted blocks, web addresses (including a bare domain with a path, such as example.org/page), Markdown link targets or email addresses is changed. The visible text of a link can be.
None of these characters proves who wrote a text, and removing them does not stop a detector from flagging it.
What we log
When a run fails or a limit or security check trips, our error log records your IP address, browser, the page address and a session ID, never your text. Every run is also logged for usage statistics (a random ID for this browser session, plan, time), without its text.Rewrite
Your rewrite appears here.

Numbers, names, links and longer quotes were checked. Meaning wasn't, so read the result before you use it.
Scores are the AI-likeness (0–100) from our open-source e5-small classifier, run in your browser; nothing is sent anywhere. It is one detector, it is often wrong, and it is not what your school or client uses. Long text is scored in ~1,200-character parts and averaged by word count, the same way our AI Detector page does (that page also blends in a pattern scan, so its headline number can differ).
How it works
- Protected parts stay out. Fenced code blocks, Markdown tables and quoted passages (lines starting with
>) are never sent to the model. They come back exactly as you pasted them. - Long text is split. Text with more than about 4,500 characters of prose is split at paragraph breaks into parts, rewritten together, and put back in the original order. Each part is told it is one piece of a longer document.
- One AI rewrite per part. The model is told to keep the meaning, facts, names, numbers, quotations, citations and links, and to cut generic framing, filler and formulaic phrasing.
- Facts are checked before you see it. Every number, date, time, duration, price, percentage, multiplier and unit in your text must still appear with the same value (5 km stays 5 km; a value you repeat only has to survive once). A minus sign counts, and "at least" can't become "at most". Value words such as "noon", "twice" or "a fortnight" may be dropped, but not swapped for another value. So must links, emails, citations, quotes of three or more words, inline code, weekday and month names, and names of two or more words: a different first name before a surname is caught, and any other name must keep every word. A rewrite that changes one of these, or adds a number, link, citation, quote or inline code that was not in your text, is rejected and you are not charged. So is one that was cut off, refused, in another language, or far shorter or longer than your text. In Social mode a count may be left out (never changed); in Technical mode "Step 3:" labels are structure, but their order is checked.
- Meaning is not checked. A flipped "not", a softened claim, a dropped clause with no fact in it, a dropped "at least", an added name, a changed one-word name, a changed title (Mrs to Mr), two people's roles swapped or two values swapped between clauses can get through. Read the result before you use it.
What it can't do: it can't tell whether your facts are true, and it can't add the specific detail or opinion that only you have.
Limits by plan
| Plan | Runs | Characters per run | Modes | History |
|---|---|---|---|---|
| Guest (no account) | 5 per calendar month | 5,000 | General | No |
| Free account | 10 per 30 days | 10,000 | General | No |
| Basic $9.99/month | 100 per 30 days | 25,000 | All 8 | 30 days |
| Pro $29.99/month | 1,000 per 30 days | 50,000 | All 8 | Until you delete it |
Member periods run for 30 days from your first run in the period. A run is only counted when you get a rewrite back; errors on our side are free. There is also a short-term cap of 5 attempts a minute. A text that comes back unchanged is never counted.
Three daily safety caps protect the service. None of them uses up your monthly runs, and all three reset at midnight UTC:
- Rewritten parts you receive: guest 20, free 80, Basic 400, Pro 1,500 a day. A long text uses one per part. Failed attempts don't count toward this cap.
- What an account's rewrites may cost us in model fees: free $0.25, Basic $1.00, Pro $2.50 a day. Failed attempts do count toward this cap, because they still cost us.
- Failed attempts: if our rewrites keep failing for you (guest 40, free 160, Basic 800, Pro 3,000 failed parts in a day), new attempts pause until the reset. Nothing is charged for them.
Modes
- General
- Edits your text in its current form: same purpose, audience and formality.
- Copywriting Basic and Pro
- Sales and product copy. Told to keep the offer and calls to action, and not to add proof, scarcity or guarantees. These are instructions to the model, not checks.
- Marketing Basic and Pro
- Campaign content. Told to keep the message and brand voice, and not to add unsupported claims. These are instructions to the model, not checks.
- Academic Basic and Pro
- Scholarly register. Told to keep citations, qualifiers and claim strength, and never to invent a source. Of these, an added or changed citation and a changed quotation of three or more words are caught; a softened claim is not.
- Blog Basic and Pro
- A readable blog voice. Told not to invent experiences, opinions or examples for you. That is an instruction to the model, not a check.
- Social Basic and Pro
- A finished social post. Told to keep handles, hashtags, links and facts, and to add no engagement bait. Links are checked; a count may be left out, and handles and hashtags are not checked.
- Email Basic and Pro
- A natural email body. Told to keep names, dates, commitments and requests. Dates and names of two or more words are checked; commitments, requests and one-word names are not.
- Technical Basic and Pro
- Documentation and instructions. Told to keep code, commands, identifiers and step order exactly. Code blocks, inline code and the order of "Step N:" labels are checked; commands and identifiers in plain prose are not.
Questions
Will the rewrite get past an AI detector?
We do not promise that, and the tool is not built for it. It removes mechanical tells of AI drafting so the text reads like a person wrote it. Detectors disagree with each other and change often, so no tool can guarantee a result.
Can I use it to hand in AI-written work as my own?
No. It is not a way around academic integrity rules. If your school, publisher or client requires you to disclose AI use, rewriting the text does not change that.
Does it change my meaning?
It can. Before you see a rewrite we check it against your text: numbers, dates, times, units, links, emails, citations, quotes of three or more words, inline code and names of two or more words must survive with the same value, and a rewrite that changes one, or adds a number, link, citation, quote or code that was not there, is rejected and you are not charged. In Social mode a count may be left out, never changed; in Technical mode step labels are structure. Meaning itself is not checked: a flipped "not", a softened claim, a dropped clause with no fact in it, an added name or two values swapped between clauses can get through. Read the result before you use it.
Is it free?
Guests get 5 runs a month of up to 5,000 characters. A free account gets 10 runs of up to 10,000 characters. Basic ($9.99/month) gets 100 runs of 25,000 characters and all modes; Pro ($29.99/month) gets 1,000 runs of 50,000 characters. A run that fails on our side is not counted.
Do you keep my text?
The humanizer does not store the text you paste. On Basic and Pro you can tick "Save rewrites to my history" (off until you turn it on); then the rewrite, its mode, word count and date are saved, never your original. Basic history items are kept for 30 days, Pro items until you delete them.
Can I use the output commercially?
Yes. We claim no rights to the rewritten text.
