About AI or Not
We build tools that help people understand AI-generated content — detect it, analyze it, and see which parts look machine-written. Free, instant, and accessible to everyone.
Our Mission
AI-generated text is everywhere — in classrooms, newsrooms, and workplaces. As AI writing tools become more powerful, the ability to distinguish human writing from machine output has become essential.
AI or Not exists to make AI detection accessible. We believe everyone should be able to verify content authenticity without paying for expensive enterprise tools or creating yet another account. That's why our detector is free, requires no sign-up, and works instantly.
What We Build
AI Detector — Paste any text and get an instant risk score with sentence-level analysis. Our detector identifies specific AI writing signals including vocabulary patterns, sentence uniformity, and predictability metrics.
Multimodal Detectors — Beyond text, AI or Not checks images, video, voice, and music, so you can verify almost any kind of content from one place.
How Our Detection Works
Our AI detector uses multiple layers of analysis to evaluate text authenticity.
Pattern Analysis
We analyze sentence structure, vocabulary diversity, and transition patterns that distinguish human writing from AI output.
Sentence-Level Scoring
Every sentence is individually classified, so you see exactly which parts of your text triggered AI detection signals.
Explainable Results
We don't just give you a number. Every detection includes specific signals explaining why the text was flagged.
Our Principles
What guides how we build and operate AI or Not.
Transparency Over Verdicts
AI detection is probabilistic, not definitive. We show you the signals and let you decide — we never claim absolute certainty.
Free and Accessible
Core detection is free with no account required. We believe content verification shouldn't be locked behind paywalls.
Continuous Improvement
AI models evolve constantly. We update our detection to keep pace with the latest models including GPT-4, Claude, and Gemini.
Try It Yourself
Paste any text into our detector and get an instant analysis — free, instant, and no sign-up required.
