Why HumanGPT
Most AI drafts give themselves away with the same stock words and the same rhythm. HumanGPT edits those habits out and leaves your content alone.
Natural rhythm and plain words, with no "delve" and no "in today's fast-paced world". Pick a tone and a text type, or let it follow a sample of your own writing.
Facts, names, numbers and citations stay as you wrote them. After every rewrite, a second check compares it with your original, corrects anything that changed and lists anything still missing.
A built-in AI-likeness estimate rates every sentence. You see which lines still read like a template, and you can rewrite just those.
Paste text, scan a page or bring in a Google Doc, PDF or Word file. Every result is saved as a document in your account, ready when you come back.
Before and after
Pick a type of writing to see a typical AI draft next to the HumanGPT version. The colors show how each sentence scored on the AI-likeness estimate.
In today's fast-paced world, social media plays a pivotal role in shaping the multifaceted identities of adolescents. Furthermore, it is important to note that these platforms serve as a double-edged sword, offering both connection and comparison (Lee, 2021).
Social media has a big say in how teenagers see themselves. The same apps that keep them close to their friends also push them to compare their lives with everyone else's (Lee, 2021).

These are examples. Results depend on your text, and the score is always an estimate.
How it works
Checking a text costs no words, so you can see where a draft stands before you change anything.
Type or paste your draft, scan a page or open a link to a Google Doc or web page. On Pro you can also import PDF and Word files.
See the AI-likeness estimate for the whole text and a color for every sentence, so you know which parts need work.
Choose a tone, a text type and how much to change. The button shows how many words the run uses and how many you have left.
A word-by-word diff marks every edit. Copy the result, share it or export it as a Word file, a PDF or plain text.
Features
One editor for checking, rewriting and sending, with a clear record of what changed.
Each sentence gets a color from green to red, and the whole text gets a score from 0 to 100. The estimate combines a check for known AI writing patterns with a rating from an AI model.
It shows how much a text follows AI habits. It can't prove who wrote something, and we always call it an estimate.
We moved the team offsite to the lake house in May. The retreat served as a testament to our unwavering commitment to collaboration. Everyone came home with fresh ideas and a clear plan.
Tap a red sentence to rewrite only that one ProAfter each rewrite the app compares numbers, names, quotes and citations such as (Smith, 2021) or [12] with your original. A fact-check pass corrects anything that changed, and anything still missing is listed.
Tell it what you're writing and how it should sound. A light, balanced or strong setting decides how far the rewrite may move from your draft, and the result stays in the language you wrote in.
TonePaste a sample of your own writing, up to 2,000 characters. The rewrite follows its sentence length, word choice and punctuation, so the result reads like your other work.
Quick update: the draft's done, two charts still need work, and I'll send it over on Friday. Shout if the intro feels long.
Bring a draft in from a file, a photo or a link. Photos and camera scans are read on your iPhone.
Removed words are struck through and new words are underlined. A short "What we fixed" list names the habit behind each edit.
The results serve as a testament to show how much the method helps.
Copy the result, send it to another app or save it as a Word document, a PDF or plain text. Paragraphs, lists and headings come through intact.
Every humanize is saved as a document with its last 10 versions, so you can go back to an earlier one. Sign in with Apple or Google to keep your documents when you switch iPhones. Signing in is optional.
What it fixes
The rewrite works from a checklist based on Wikipedia's guide to signs of AI writing, grouped by the habit behind each one. It fixes the strongest first and leaves alone anything that's fine in context.
The checklist is adapted from the open-source humanizer skill by Siqi Chen (MIT License) and Wikipedia's Signs of AI writing, maintained by WikiProject AI Cleanup.
Pricing
A run costs the number of words you send in. The length of the rewrite doesn't count, and if a run fails, the words go straight back to you.

FAQ
Something else on your mind? The support page covers imports, errors and billing, or you can email evolutiongamesapps@gmail.com.
Yes, you can start without paying. Your first humanize run is free, and after that you get 300 words every day, up to 300 words per run. Pro adds more words, longer runs, sentence rewrites, PDF and Word import and voice matching.
A score from 0 to 100 that rates how strongly a text follows patterns common in AI-generated writing, plus a color for each sentence. It combines a check for known patterns with a rating from an AI model. It's an estimate: it can't prove who wrote a text, and other tools may score the same text differently.
No, and no honest tool can. HumanGPT helps your writing sound natural and like you, and the estimate shows how it reads. How a teacher, an editor or a detection tool judges a text is up to them.
It's built not to. The rewrite is told to keep every fact, name, number, quote, citation and link. Afterwards the app compares the rewrite with your original. If something changed, a second AI pass corrects it, and anything still missing is listed so you can put it back.
The app is available in English, German, Spanish and French. You can humanize text in other languages too, and the rewrite stays in the language you wrote in. English gets the most thorough edit, because the pattern checklist was written for English.
Any run of characters between spaces that contains at least one letter or digit, so a lone dash or bullet is free. A run costs the words you send in, whatever the length of the rewrite. Checking the AI-likeness estimate doesn't use any words.
It goes to our backend in the EU and to Replicate, our AI processing provider, which runs Anthropic's Claude models. They use it only to produce your result. Documents you save sync to your account and are deleted as soon as you delete them. We keep a copy of each rewrite result for 30 days for retries and abuse prevention. There are no ads, and we don't sell your data. The privacy policy has the details.
No. The app sets up an anonymous account the first time you open it. If you want your documents on another iPhone or after reinstalling, sign in with Apple or Google in Settings. You can delete your account and everything in it from Settings at any time.
The weekly Pro plan starts with 3 free days for eligible new subscribers. If you don't cancel at least 24 hours before the trial ends, it becomes a paid weekly subscription at $5.99 a week (US price). The yearly plan has no trial.
Open the Settings app on your iPhone, tap your name, then Subscriptions, and choose HumanGPT. You can also get there from Manage subscription in the app's Settings. Deleting the app doesn't cancel a subscription. The support page covers refunds and restoring purchases.
That depends on your school. Some allow AI help, some ask you to disclose it and some forbid it. Follow the rules of your school or workplace. HumanGPT works best on drafts that are already yours.
Not yet. HumanGPT is available for iPhone. We're planning a web editor that uses the same account and documents.
