Banning AI at work failed everywhere. Sealmatter is the membrane instead: every identity is swapped for a consistent stand-in before anything leaves, restored only inside your walls, and every case closes with a certificate in a public register that outlives us. Nobody outside, including Sealmatter, ever sees a name. No zero-retention promises needed, because there is nothing to retain.
Claude, ChatGPT, Harvey, Legora, your own API workloads. Nothing to abandon; Sealmatter connects in front of them.
Folders, Drive, mailboxes, SharePoint. Sealed copies are mirrored with your existing permissions; no second document system, no second user list.
Every matter ends with a named signature and a certificate countersigned into an append-only public register, verifiable offline, years later, even without us.
Connect once. In Claude or ChatGPT, documents arrive already sealed through a connector; the model works on Person A and ID-40017 and delivers results back for restoration. API tools change one address. Platforms like Harvey and Legora simply read the sealed mirror.
Documents from your folders, mailboxes and uploads are read once, and every person, number and address becomes a consistent stand-in. The mapping never leaves your instance.
Your teams use the AI tools they already have, on sealed content only. Nothing changes in their day.
AI output returns through the membrane and is rehydrated at the trusted endpoint, with a sweep report: what was restored, what stayed generic, and that nothing was falsely restored.
A second model attacks the sealed output and scores it. One named person signs, once. The certificate enters the public register.
Regarding the departure of Katharina BrennerPerson A, employee number DE-88231ID-40017, her manager T. OseiManager 1 confirmed the review was closed. Records for DE44 5001 0517 5407 3249 31IBAN withheld and the address Torstrasse 118, BerlinAddress 3 are retained under the statutory schedule.
One stand-in per identity, consistent across every page of the matter. The model reasons perfectly; it just never knows who.
Zero setup, EU jurisdiction storage, signed data processing agreement. Running in minutes.
The whole platform deploys into your own cloud account. Sealmatter never sees a byte of content; only certificate hashes reach us.
Runs on your hardware with local models. Documents never leave the building, full stop.
Every certificate is countersigned into an append-only transparency register with a published daily root and an inclusion proof embedded in the certificate itself. A regulator, court, client or insurer can verify any certificate at verify.sealmatter.com, or offline against the published roots, without an account, without trusting us, and without us still existing. A certificate outside the register is not a Sealmatter certificate.
