Frequently Asked Questions
Everything you need to know about the UnAIMyText AI Checker.
1What is the UnAIMyText AI Checker?
It estimates how likely a piece of writing was generated by AI. You paste text, upload a file, or check a URL, and it returns a percentage plus the sentences that most affect that score.
2Is the AI checker really free?
Yes. Checking up to 3,000 words does not require a sign-up or an account.
3Do I need to create an account?
No. You can run a check without signing in. Your recent checks appear under History, which is saved in this browser only, not in an account.
4How many words can I check at once?
Up to 3,000 words per check, with a minimum of 50. Split anything longer into sections.
5How accurate is the AI checker?
It is an estimate, not proof. It can miss heavily edited AI text and can flag careful human writing. Use the score to decide what to reread, not as a final judgment.
6Which AI models can it detect?
It looks for writing patterns common in generated text, not a signature from one model. It is not limited to a single tool, and it will not catch every one.
7Can I upload a PDF or Word document?
Yes. Upload a PDF, Word (.docx), or plain text file, or paste the text directly.
8What does the AI percentage mean?
It is the share of the sample the checker reads as likely AI-generated. A low score means mostly human-looking writing. A high score means several passages match generated patterns. A mixed score means both are present.
9Will it show which parts are AI-generated?
Yes. Sentences that raise the score are highlighted, so you can review those lines instead of rewriting the whole piece.
10Can I use this for school assignments?
Yes, as a check before you submit. The score is not an academic finding. Your school's rules still decide what is allowed.
11Is my text stored or shared?
A check is processed to produce the result. Do not paste passwords, private records, or anything you cannot share with a processor. Signed-out checks are not added to a public library. Your History list stays in this browser, and you can clear it at any time.
12Can I check a website URL?
Yes. Switch from Text to URL, paste a public link, and the checker reads the page text it can fetch. Pages behind a login or paywall may not work, and long pages are checked up to the first 3,000 words.
13Is this the same as a plagiarism checker?
No. A plagiarism checker compares your text with other sources. This estimates whether the writing looks AI-generated. A piece can be original and still look generated, or copied and still look human.
14How can I make my text sound more human?
Edit the highlighted lines first: vary sentence length, cut stock phrases, and add a detail only you would include. Or use Humanize to rewrite those passages while keeping the original meaning, then read the result before you send it.
