AI Content Detector
An honest estimate with reasons — not a fake certainty score.
Free to use — fair-use limit of 15 AI runs per hour. Results are AI-generated: always review before publishing.
The HN Solutions AI Content Detector estimates whether text was written by AI or a human — and unlike tools that claim “99.2% AI” with false precision, ours gives you an honest likelihood range plus the specific signals it noticed: uniform sentence rhythm, hedging patterns, generic phrasing, missing personal detail. Because the truth is that no detector, anywhere, is definitive.
How to use the AI content detector
- Paste at least a full paragraph — detection on short snippets is guesswork, so we require ~120 characters minimum.
- Click Analyze and read the likelihood score, verdict and signals.
- Treat the result as an informed estimate. Never punish a student or writer on a detector score alone — false positives are real and well documented.
Frequently asked questions
How accurate are AI detectors?
Imperfect — all of them. Formulaic human writing gets flagged, and edited AI text slips through. Ours is honest about that uncertainty instead of inventing decimal-point confidence.
What signals suggest AI writing?
Uniform sentence lengths, an absence of personal specifics, over-hedged claims, generic transitions (“moreover”, “in conclusion”), and suspiciously even tone throughout.
Can text pass as human after editing?
Heavily edited AI text becomes, in a real sense, human-edited writing — detectors reflect that, which is another reason scores are estimates, not verdicts.
Is this free?
Yes — 15 checks per hour, no account.
Writing content yourself? Draft with the AI writer and make it yours — then this detector, the grammar checker and the density checker form your pre-publish checklist.
