Guide
How to humanize AI text, and why detectors misfireWhat people use it for
- Your own drafts see which lines in an AI-assisted draft still read like a template before you send or submit it.
- Copy that sounds generic find out why a cover letter, product page, or pitch reads like a template, with the lines quoted.
- Edits before publishing spot the stock phrases and buzzwords in website or social copy so you can cut them.
- Learning the tells see each pattern named and quoted, so you can catch it yourself next time.
Questions
Can it prove a text was written by AI?
No, and no detector can. askROI reads the text for patterns AI writing is known for and tells you how it reads, with the lines behind that reading, but it cannot know who wrote it and gives no percentage or score. People write formulaic text too, especially in formal, technical, or second-language writing, and edited AI text can read as human. No detector is reliable enough to accuse anyone of using AI, especially a student.
Is the AI detector free?
Yes. You can check text on the free plan. Paid plans raise the usage limits and include more credits for Premium mode.
Should a teacher use this to check a student's essay?
Not as evidence. No AI detector is reliable enough to accuse someone of using AI, and that matters most for students, whose grades and records are at stake. A reading from askROI can start a conversation about how the essay was written, but drafts, notes, version history, and talking with the student tell you far more.
What does it look for?
Stock openers and closers, buzzwords like "delve" and "pivotal", formulas like "not just X, but Y", forced groups of three, generic transitions, repeated phrasing, and sentences of near-identical length. It also notes what reads as human, such as specific facts, first-hand detail, and uneven rhythm, and quotes the exact lines either way.
Will it tell me what other AI detectors will say?
No. askROI cannot predict another tool's result, and detectors can disagree about the same text. It explains how your text reads so you can decide what to change.
Can it rewrite the text afterwards?
Yes. Reply "humanize it" and askROI rewrites the text to cut the patterns it found, keeping every fact, name, and number. The AI humanizer does the same from its own page.
