What is Deep AI Detector?

Deep AI Detector is an AI content detector that reads any text you paste — essays, manuscripts, articles, emails, reviews, press releases, marketing copy — and tells you whether it was written by a person or generated by 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 with no signup, five per month with a free account, or unlock higher limits on paid plans starting at $14.99/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 AI detection tools typically misclassify as human. The model is updated regularly as new model families enter circulation, and the same model runs on every tier (only quota, word limit, and feature gating differ).

How Deep AI Detector works

You paste text. We score every sentence against the advanced detection model trained on 2 billion+ samples. The result is a per-sentence verdict (likely human, likely AI, mixed), an overall score, a confidence band, and on paid tiers a downloadable PDF + JSON report you can attach to an academic appeal, an editorial review, or a hiring decision. Detection runs on the original text — no upload step, no copy/paste to a foreign portal, no waiting.

Why we built an explainable AI text detector

Most AI detection software hands you a single number and walks 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.

What sets Deep AI Detector apart

Three commitments shape every release. First, paraphrased AI catching: humanized rewrites that legacy AI detectors classify as 97%+ human are exactly the cases we tune for. Second, multilingual coverage: paste in any of 20+ languages and get a verdict on the original text. Third, transparent pricing: the whole grid lives on /pricing, with no hidden per-token fees, no aggressive retention calls, and no upsell traps inside the dashboard.

Who uses Deep AI Detector

Deep AI Detector serves anyone whose decisions depend on knowing whether text was written by a person. The use cases below are the workflows that drive most of our paid traffic.

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 content detection into their own apps via our REST API (launching from the Pro tier onward).

How Deep AI Detector helps

The free tier covers occasional checks. Paid tiers cover the workflows where detection is part of the job — and the differences are practical, not gimmicky.

Accuracy on every major model family

The advanced detection model is trained on a balanced 2 billion+ sample corpus covering ChatGPT, Claude, Gemini, Llama, Mixtral, DeepSeek, Qwen, GLM, and every paraphrased and humanized variant we could collect. It is retrained as new model families ship, so a fresh ChatGPT release does not silently degrade detection accuracy for two months.

Explainability you can actually defend

Every verdict carries per-sentence highlights and a confidence band. Reviewers know not just the verdict but where the evidence lives. That is what makes the result defensible in an academic appeal, an editorial review, or an HR conversation — you can point at the specific sentences that triggered the AI verdict instead of waving a number.

Privacy as default

Submitted text is deleted from logs and cache within 24 hours unless you explicitly opt into history. We never train on your data without per-user opt-in. The cache stores hashed results, not plaintext, so identical text returns a cached verdict without either copy ever being stored in plaintext.

Paid-tier features

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 (coming soon from Pro tier upward) REST API access with webhooks.

Pricing transparency

Deep AI Detector publishes the entire plan grid on a single page. Free tier with no card, paid tiers from $14.99/month up to $999/month, and one-time word packs from $5 (50,000 words) to $5,000 (175 million words) that never expire and stack on any subscription. Pay-as-you-go runs at roughly $0.25/detection with no monthly commitment. Cancel any time from your dashboard — no penalty, no retention call.

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.
