Textumi and Scribbr at a glance
Checked on 20.10.2026. Scribbr runs a website for each country, and the details of its AI detector differ between them, so the table names the site each fact comes from. Textumi facts come from our product.

How each tool shows a result
Textumi puts a needle on a scale from “Human” to “AI” and labels it with one of five labels, ranging from “Human-written” to “AI-generated”. With an account, you also see which parts of the text influenced the result most. If a text is less than 50 words long, it shows “Too little text to judge” rather than a label.
Scribbr uses a percentage score ranging from 0% to 100%. The French version of their website adds that the AI detector highlights the parts of the text that were likely generated or edited by AI. The German version states that the score represents the likelihood that the text was written by AI.
A label and a percentage are both a model's estimate from the wording. Neither proves who wrote a text, and a percentage is not the share of the text that was generated.
Which languages each detector covers
Textumi can detect AI writing in 20 text languages. The detectors for English and Ukrainian have the longest history. The other language detectors were built and tested on a smaller set of texts, and some of them fail to detect many AI texts in other genres, so results from those detectors are steadier when the text is longer.
Scribbr's language coverage depends on the country site you use. Its UK site mentions English texts. Its French site names French, English, Spanish and German for checks with and without premium. Its German site offers free checks for English texts only and adds German, French, Spanish and Dutch in premium, while its Spanish site checks Spanish texts without premium.
Rewriting a draft: two different approaches
Textumi's Humanizer lives in the same account as the detector. It takes a draft and rewrites it so that it sounds more natural, then tests the new version against your original by comparing the facts, names, numbers, exact names (such as quoted labels), and the logic of each sentence. Any version that fails these tests is not shown, and your original is displayed next to the result.
The Humanizer takes 50 to 2,000 words in English and up to 1,000 words in the other languages. It does not promise a lower score in any detector.
Scribbr lists an AI humanizer that aims to make AI writing sound natural, and a paraphrasing tool that rewrites text in your own words. Both are separate tools on its website.
Where you can use each tool
Textumi operates in four different locations with one account. The web workspace takes in pasted text, files, and public web pages. Textumi for Chrome checks and rewrites text on any web page from a side panel. Textumi for macOS keeps the AI Detector and the Humanizer on a toolbar above your other apps. A Mac with Apple silicon is required to run the program. The MCP connector lets Claude, ChatGPT, and other assistants check and rewrite a text with Textumi directly in the conversation.
Scribbr's AI detector works on its website. We found no desktop app, browser extension or document add-on for it on Scribbr's pages.
Privacy and history
Textumi stores submitted texts and results encrypted and detection is run on Textumi's own servers. Rewriting also passes the text to the external AI model provider named in our privacy policy. On Individual and Professional plans, your private History keeps your requests for 30 days, and you can delete them earlier. If you run a check without an account, then no text is kept.
Scribbr's UK and German detector pages say that the texts you check are neither stored nor shared. For its full rules, read Scribbr's privacy policy.
Who each tool suits
Scribbr suits students who want an AI check, a plagiarism check and rewriting tools from one academic writing service, and who need checks of long documents in premium. Its free check needs no account and has no limit on the number of checks.
Textumi is for you if you want one account for the detector and a Humanizer with fact checks, a native app on your Mac, or checks and rewrites from inside your AI assistant. It is also for you if you prefer a plain label with the passages behind it to a percentage, or if you frequently check Ukrainian texts.

आम सवाल
Is Textumi an alternative to Scribbr's AI detector?
It depends on your need. If you want a detector and a Humanizer with fact checks together in one account, a macOS app or a connector to your AI assistant, you could use Textumi. If you want an AI check and a plagiarism checker in one academic writing service, then Scribbr has that, but Textumi does not check plagiarism.
Which detector is more accurate, Textumi or Scribbr?
We do not make that claim. Every company tests on its own texts, and the results are not comparable. Any detector can flag human writing and miss AI writing, especially on short texts and edited/translated ones. The fairest test is your own: check a few texts you know the origin of with both and compare what each one shows.
Can I use either tool without an account?
Yes. Scribbr offers unlimited free checks without an account, within the word limit of the site you use. Textumi's AI Detector checks texts of 5 to 250 words without an account, up to three times a day, and the Humanizer needs an account.
Does Scribbr's detector check for plagiarism?
No. Scribbr's AI detector estimates whether a text was written by AI, and its plagiarism checker is a separate tool that compares a text with existing sources. Textumi does not check for plagiarism at all: its detector looks at whether the wording resembles AI writing.
Is Scribbr's AI detector related to QuillBot?
Scribbr's Spanish detector page says the detector runs on the QuillBot service, owned by Learneo, and is covered by QuillBot's terms. Textumi uses its own detector models, built and tuned in-house. We also compare Textumi with QuillBot on a separate page.
Written by ChatGPT? Can either tool tell me?
Both are reading the text, not the history of it. The Textumi detector never mentions a model, and we have not tested it separately on ChatGPT, so it makes no claim about any specific model. A label or percentage is just an estimate based on style, and is not proof of the authorship, whichever tool shows it.
