One text submission within your tier's word limit, scored by our advanced AI detection model. Per-sentence verdicts on Starter and above. Real-time analysis — sub-second response on most documents.
You can either upgrade your plan or top up via PAYG (roughly $0.25/detection, varies with document length). No automatic overage charges. The dashboard shows your usage in real time so there are no surprises.
Yes. Cancellation is self-service from your billing dashboard — no penalty, no retention call. Access continues through the end of the current billing period. See the refund policy for what happens to unused time.
Refunds are based on unused service. Any billing period in which a detection was performed is non-refundable. Cancel any time from your billing dashboard and we'll refund the unused portion of your subscription. Unused PAYG credits and word-pack balances are refundable; consumed credits are final. See the full refund policy or email [email protected] for help.
We pass through the savings instead of marking up the margin. Industry-leading accuracy at every volume tier without the legacy-detector premium. The pricing grid above is the whole offer — no upsells, no per-token surprises.
REST API access is coming soon on Pro tier and above. The web dashboard, exports, and per-passage highlights all work today. Preview the API docs → or drop your email to be notified when API access goes live.
One-time, never-expire detection credits. Buy a pack ($5 - $500), credits land in your account immediately, and they get consumed when you run detections. They stack on top of any subscription tier — when your monthly quota is exhausted, credits kick in automatically — and they work standalone on the free tier too. The bigger the pack, the lower the effective per-word cost.
Never. Once purchased they stay in your account until consumed. If you let the subscription lapse the credits remain available — sign back in any time and they're still there.
Trained on 400,000+ labelled human and AI passages covering ChatGPT, Claude, Gemini, Llama, Mixtral, DeepSeek, Qwen, GLM, and every other major LLM family released in the last three years. Plus paraphrased and humanized AI text that legacy detectors typically miss.
Submitted text is deleted within 24 hours unless you explicitly opt into detection history. We never train models on your text. Hash-based caching means even our cache never stores plaintext. See the privacy policy for the full breakdown.
