Detection your committee can actually verify.
Every Proofline result is Ed25519-signed and reproducible on your own hardware — deployable on-prem or air-gapped, sized to your case count. Request a trial and run it on your own documents; we'll reach out to set it up.
Verifiable, not asserted
Signed benchmark artifacts you recompute yourself — where competitors publish a headline accuracy with no way to check it.
Your text stays yours
On-prem & air-gapped deployment. We do not sell, monetize, or train on your content.
Runs on your CPUs
No GPU, no data center, no third-party API in the detection path — which matters for procurement and security review.
Compliance in progress
We're establishing the protocols to reach formal certification; current posture and documentation on request.
We'll reach out shortly.
Thanks — your request is in. Someone from our team will contact you to set up your trial. In the meantime you can run a document through the tester.
Where institutions put Proofline to work
Academic-integrity review that survives an appeal
A signed, reproducible result a student — or a review board — can independently verify, instead of an opaque score. Matters where detectors are documented to misflag non-native writers.
Submission & content screening at volume
Batch-check manuscripts or contributed content through your own pipeline, with an audit trail you keep — no third-party service holding your text.
Air-gapped, procurement-ready
Runs entirely on your CPUs with no external calls in the detection path — the property a security review needs before anything is approved.
Non-English coverage the leaderboards skip
Full-document scoring in any language on the verifiable pipeline, where most public benchmarks report English only.
| What buyers ask | Typical AI detector | Proofline |
|---|---|---|
| Can we verify the accuracy claim? | Headline number, no method | Signed artifact you recompute |
| Does our text leave our network? | Sent to a hosted API | On-prem / air-gapped option |
| Is there generative AI in the loop? | Often another model | None in the detection path |
| Reproducible on our own hardware? | No | Yes — Ed25519 + OpenTimestamps |
Comparison of properties, not a head-to-head accuracy claim. Every Proofline figure ships with its signed source — see the proof page.
