Hey. That's not human.
heynotai catches AI across text, images, audio, and video — essays, headshots, voice notes, deepfakes, and anything else you can read, write, or upload.
Over 57%of the internet is AI-generated — don't be the one deceived.
Trusted by worldwide leading companies
One detector. Every kind of AI.
Switch surfaces below — text, image, audio, video, or the extension — and see exactly what the verdict looks like in context.
Spots AI in pixels — and tells you which region
Three steps. No model. No guesswork.
heynotai pipes your input through four independent detectors and reconciles their verdicts. You get one answer, not four conflicting opinions.
Drop in anything
Paste text, drag images, attach a voice memo, link a YouTube video. Or let the extension watch every page you visit.
Four models vote
Each surface runs its own ensemble — language model heads for text, vision transformers for images, spectral and prosody analysis for audio.
One honest answer
Likely human, likely AI, or uncertain — with a probability you can argue with. Never “yes/no”, never an emoji, never made up.
Built like a forensics lab.
Every part of the product is designed to give you a verdict you can stand behind in a meeting, a classroom, or a courtroom.
Browser extension
A colored trust border draws around any YouTube player in real time. Click for the full verdict.
Works on any page
Text fields, image previews, embedded videos — heynotai watches the DOM and verifies in place.
Reports you can defend
Every verdict ships with the model breakdown, the flagged regions, and the confidence interval. Export as PDF.
Privacy-first
Nothing leaves your device unless you ask. The browser extension runs locally; the API is opt-in.
Honest about uncertainty
Three verdicts: likely human, likely AI, uncertain. Never a fake 100%, never a hallucinated reason.
Eight detectors, one API
Text, image, audio, video, deepfake, voice clone, watermark, paraphrase. One auth, one bill.
What teams say after a week.
We caught seventeen AI-written cover letters in a single morning. Two months ago we wouldn't have caught any. heynotai is now the first thing every reviewer opens.
I read the regional flags on a student's essay before I read the essay itself. It's not a verdict on the student — it's a starting point for a conversation.
The trust border on YouTube has changed how my team reviews source video. We can tell at a glance whether to dig in or move on.
Questions, honestly answered.
