Ten years of matters, contracts and memos sit in the file system. Finding a position means remembering who wrote it. Perimeter reads the firm's own work product and answers with the source paragraph — on an appliance in your office. No cloud is involved.
Bring one question your team spent an afternoon on — we show how it gets answered
Every position the firm has argued lives in a brief, a memo or a matter file. It gets researched again because nobody can find it — billed hours spent rebuilding the firm's own work.
The archive problemis often the only index to a decade of matters. When that partner is in court, on leave or at another firm, the search stops.
Institutional memory, single point of failureyour matter files and client correspondence should ever visit. Professional secrecy is not a policy preference. It is the profession.
The reason this is an applianceClient files are privileged. A cloud AI subscription puts them on infrastructure you do not control, under law you did not choose. That is not a compliance footnote. It is a professional risk with your name on it.
Perimeter removes the question instead of arguing it. The appliance sits in your office and makes zero external calls — verifiably, on your own firewall. There is no transfer to assess, no processor to vet, no foreign statute to read before you can use AI on your own files.
Your research database covers the law. Perimeter searches YOUR matters, contracts and memos — the material you can't upload anywhere. It reads, retrieves and answers with sources. Nothing is sent anywhere.
Defences, claims, positions argued and won. "Have we taken this point before?" — answered with the matter and the paragraph.
Templates, negotiated clauses, internal memos. The firm's accumulated judgement, searchable by meaning rather than filename.
Advice given, positions taken, deadlines agreed — cited by letter and date, visible only to the lawyers cleared for the matter.
We fix a reference set: real questions from closed matters, with answers your lawyers know are in the files. That is the benchmark — yours, not ours.
We agree the acceptance threshold on your set — share of questions answered with the correct source, first try. Miss the gate, and there is no licence invoice. Only the pilot work is paid.
Answer quality on your archive, time to find against the old way, access rights verified matter by matter. The same numbers go to the partners' meeting.
One page for your IT lead or DPO: architecture, zero-egress proof, EU hardware supply chain, DPIA template. Built to survive the review without a meeting.
One practice group, one archive. A serious pilot, honestly priced. Most firms start here.
Archive search for the whole firm, access rights per matter, training included, load-tested for your users.
Multiple offices, heavier hardware, priority SLA.
Support is 20% a year and includes model updates. Hardware at cost +15–20%, bought in the EU under your name. Full pricing
Yes. Perimeter follows the access structure you define — by user, group or matter. An information barrier in your firm is a barrier in the index. The setup is verified during the pilot, not promised.
The same way your file permissions should: a lawyer can only search what they are permitted to open. A screened lawyer gets no results from the walled matter — and no hint that a result exists.
Yes. The architecture fits on one page, the zero-egress claim can be checked on your own firewall, and code and architecture review is available on request. Send them the security brief.
No. Your research database covers the law. Perimeter covers your firm — the matters, contracts and memos you cannot upload anywhere. The two answer different questions.
Every answer carries its citation — matter, document, paragraph. A lawyer checks the source, not the summary. And the pilot measures answer quality on your own archive before any licence exists.
No. The box arrives configured; training is two sessions. Support covers updates — including model updates — for the year.
A short call, no slides. Bring a question your team spent hours on last month — we show how Perimeter answers it on a sample archive, and how the pilot proves it on yours.
