Article 53(1)(d) of the EU AI Act asks general-purpose AI providers to publish a detailed summary of training data — and gives rights-holders the standing to contest what's there. PartSentinel structures the technical evidence your legal counsel needs to draft that contestation. We don't draft it for you; that's what your counsel does.
PartSentinel is not a law firm and does not provide legal advice. We structure technical evidence — audit logs, exposure registers, provenance manifests, DPIA-ready data flows — that your legal counsel uses to draft a regulator-facing response. The signed file, the legal strategy, and the filing decision are your counsel's, not ours.

OpenAI, Anthropic, Google must declare what their models know. The problem: they cannot prove what their models actually know about your industrial catalogue. PartSentinel is the only tool that measures it empirically. The gap between what they declare and what they actually know is the Data Integrity Gap.
Up to €15M exposure per LLM provider. PartSentinel's empirical measurements are the only court-admissible source of evidence on what a frontier model actually contains.
Decades of TecDoc / BMEcat data scraped into training sets. PartSentinel = the audit that empirically measures what models actually know — the only tool that can substantiate or contest a provider's Art. 53 declaration.
The Data Leak Source Map identifies unauthorised sources of your data in the LLMs. "Your TecDoc data is in GPT-4 without authorisation." Provenance becomes traceable, contestable, fixable.
Revised directive Dec. 2026: unlimited liability if an AI tool recommends a wrong part. The PartSentinel timestamped audit = court-admissible proof of due diligence.
Every audit generates structured data across the entire industry — an irreproducible dataset that compounds in value: the future Industry PartSentinel Index.
Generated automatically from your audit data. Designed to be handed to your counsel, dropped into a DPIA, or attached to an internal IP-protection memo — without rewriting.
PartSentinel sits firmly on the technical evidence side of the line. We document what is observable; we don't characterise its legal meaning, draft regulator-facing prose, or sign anything.
If you don't have an IP / regulatory counsel yet, we can introduce you to one of the EU firms that already handles AI Act files for industrial groups. We don't take a fee for the introduction.
Each step is documented and signed off so your counsel can rely on the chain of custody from raw model response to evidence pack.
Audit pipeline runs. Every prompt and response is logged. The provenance manifest, exposure register and DPIA diagram are generated automatically.
Single signed PDF + JSON manifest. Counsel reviews, asks clarifying questions, may request additional probes. We re-run; the chain of custody is preserved.
The legal letter, the strategy, the timing — all your counsel's call. Our role ends at the evidence pack hand-off.
Drop a single SKU into the free probe — 6 / 342 models live, 90 seconds, no account required. Then we run the counsel-ready evidence pack on your shortlist before signing anything bigger.
