Detection that earns the verdict.
Deep AI Detector is an industry-leading AI content detector trained on 2 billion+ text samples. We give you per-sentence verdicts you can act on, not a black-box score you have to defend in the dark.
What we make
Deep AI Detector reads any text you paste — articles, essays, emails, manuscripts, reviews, press releases, marketing copy — and tells you whether it was written by a person or an AI. Every detection ships with a per-sentence verdict, a confidence band, and a downloadable report on paid tiers. Try one detection per month without signup, five per month with a free account, or unlock higher limits on paid plans starting at $9/month.
Our advanced detection model is trained on a balanced corpus spanning every major LLM family released in the last three years — ChatGPT, Claude, Gemini, Llama, Mixtral, DeepSeek, Qwen, GLM — plus paraphrased and humanized AI text that legacy detectors typically misclassify as human. The model is updated regularly as new model families enter circulation.
Why we built it
Most AI detectors hand you a number and walk away. That works fine when the number is right. It's a problem when the number is wrong and a real person — a student, a freelance writer, a job applicant — has to live with the consequences. Teachers, editors, publishers, HR teams, and platform moderators need detection results they can defend to a person, not just a percentage to point at.
That's why every Deep AI Detector verdict comes with per-sentence highlighting. You can see which lines look AI-generated and which don't, share the report with the writer or the academic committee, and have a real conversation about the result instead of arguing with a number. The detection is built to be defensible — because the people using it have to defend it.
Who it's for
Deep AI Detector serves anyone whose decisions depend on knowing whether text was written by a person:
- Educators + academic integrity offices screening student submissions for undisclosed AI co-authorship.
- Editors + publishers verifying freelance copy and submitted manuscripts before they go to print.
- Content marketing teams auditing freelance writers against AI-disclosure contracts.
- Recruiters + HR reviewing candidate writing samples and statements of purpose.
- Platforms + UGC moderators catching AI-generated reviews, comments, and submissions at scale.
- Developers + product teams embedding AI detection into their own apps via our REST API.
How it helps
Deep AI Detector is built around three commitments. First, accuracy: industry-leading verdicts on every major LLM family, with the model retrained as new ones launch. Second, explainability: per-sentence highlights and a confidence band on every result, so reviewers know not just the verdict but where the evidence lives. Third, privacy: submitted text is deleted from logs and cache within 24 hours unless you explicitly opt into history, and we never train on your data without per-user opt-in.
Paid tiers add downloadable PDF + JSON reports, a strictness toggle (lenient / balanced / strict), counterfactual analysis showing how a sentence could be rewritten to score human, bulk upload for batch jobs, and REST API access with webhooks. The free tier covers occasional checks — paid tiers cover the workflows where detection is part of the job.
What we won't do
- We don't claim 100% accuracy. AI detection is probabilistic — anyone who says otherwise is selling something.
- We don't retain submitted text by default. Deletion happens within 24h unless you explicitly opt into history.
- We don't train on user submissions without per-product opt-in.
- We don't market ourselves as a substitute for academic, employment, or legal due process. Use Deep AI Detector as one piece of evidence in a larger review process — never as the sole basis for a high-stakes decision.
- We don't hide pricing or stack hidden per-token fees on top of a subscription. The pricing page is the whole grid.
- We don't sell your data, share it with advertisers, or use it for any purpose beyond delivering the detection result you asked for.
Privacy + data handling
Submitted text is deleted from logs and cache within 24 hours by default. Our cache stores hashed results, not plaintext, so identical text returns a cached verdict without either copy being stored. We don't sell user data. We don't train on submissions without explicit opt-in. We don't store IP addresses in plaintext. A PCI-compliant billing partner handles payments, so we never see card numbers. Full policy lives at the privacy page.
