Verdict and fixes
Score, evidence list, and a link to humanize if it reads like a template.

Free AI detector for pasted text
An AI detector helps you spot writing that reads like a machine template. Paste a paragraph or full draft and get a verdict: looks like AI, mixed, or human, plus a score.
The tool lists concrete signs such as stock openers, formulaic contrasts, and filler phrases. Editors, teachers, and writers use it before publish or handoff.
If the AI detector flags your draft, try Humanize text on the same site to strip templates and smooth the style. Free includes up to 5 runs per day.

Common questions
How does this AI detector work?
We scan for common AI stock phrases and patterns, then a model gives a verdict, score, and list of signs it found in your text.
Is an AI detector 100% proof someone used AI?
No. It is a style check, not legal proof. It helps spot templated writing, not authorship in court.
What should I do if the AI detector says it looks like AI?
Open Humanize text to clean stock phrases and even out the tone before you publish or hand in.
Can teachers use this AI detector on student work?
Yes, as a first pass. Treat the verdict as a hint to review closer, not as a final grade by itself.
How much does the AI detector cost?
Free up to 5 AI text runs per day, shared with other AI text tools. Pro removes the daily cap.
