Tristum reads all the case material in a matter, builds a connected case brain, and answers your questions with a citation to the exact page.
Built for British small and medium law firms.
No other product on the market finds where a party contradicts itself.
Drop the file in and leave it. When the reading settles, Tristum writes the case for your client — footnoted line by line. Question it, correct it, and what you find folds back in as a new version. Then ask it to change sides.
Your client's case, set out from the whole file the moment the reading finishes: the contentions, the figures and the chronology, each statement carrying the document it came from.
Ask, push back, correct it. Add what you know that the file does not. Every answer you keep becomes the next version of the case; the old ones stay readable beside it.
The best case against you, built from the same documents: the clause they will rely on, the email that reads badly, the figure that does not reconcile.
Connect your document stores read-only. Tristum reads everything and keeps a living, cross-linked understanding of every matter, isolated by matter ID, on your firm's own server.
Tristum sets out your client's case from the whole file: the contentions, the sums, what stands against you and where the record is thin. Every factual line footnoted.
Question the matter in plain English and search every document, message and photograph at once. Every answer carries footnotes to the exact page, and what you uncover folds back into the case as a new version.
Ask for the documents that prove a point — everything showing the works were accepted, say — and Tristum builds the bundle: ordered by argument, indexed, watermarked, with a share link, an expiry and an audit trail.
A cited timeline of the whole matter, built from every source, exportable straight into pleadings.
First drafts assembled from the file, every factual paragraph carrying its source, PD 57AC-aware. The human always signs; Tristum assembles.
Ask Tristum to change sides. It builds the case against your client from the same file, so nothing in it reaches you first from opposing counsel.
Your firm's own UK encrypted server, European AI processing, and nothing retained. Recent rulings drew a hard line: public AI tools can waive legal privilege, while closed, properly contracted tools preserve it, and verifying AI output is now a personal professional duty. Tristum is built on the right side of both.
A dedicated UK server per firm, its disk encrypted at rest. No shared infrastructure, no other firm on the machine. Segregation a managing partner can explain to a client in one sentence.
Tristum's connectors cannot write, move or delete. The evidence stays in your systems, under your control; we hold only the derived understanding, destroyed on exit.
Every AI request runs on European infrastructure, under contract, with zero retention: nothing is stored after the answer is given and nothing is ever used to train a model. Your evidence stays on your server; only the passages needed to answer a question are sent, and they are forgotten the moment it is answered.
Every answer footnoted to a real page. Verification is one click, and the audit log proves it happened, for every fee earner, on every matter.
The answer to the only question that matters is not a promise. It is machinery, and you can watch it work.
As a page renders, every quotation, figure and name is verified against the document it cites. Anything Tristum cannot find in the source is marked on the page for you to check.
Where a citation paraphrases rather than quotes, the viewer says so plainly instead of highlighting something approximate. A case built before newer evidence arrived says that too, before you rely on it.
Testers with no knowledge of the product examined 101 footnotes on a 514-document matter by hand. Every quote and figure was genuinely in the document cited. None fabricated.
Unlimited users in every band. No seat counting, no per-user audits, no 12-month lock-in. Your band is set by the size of the team using it, not the size of your firm: a disputes department of six is priced as six, whatever the rest of the practice does.
Larger teams: 41–70 fee earners £9,995 a month. Above 70, by arrangement.
Fair use: every band includes a monthly allowance of new matters — 25 on Chambers, 75 on Practice, 200 on Firm, 350 above that — set well above a normal working month. Beyond it, £25 a matter. Asking questions, rebuilding a case, challenging it and producing work product from a matter already read are always unlimited, in every band.
Your existing caseload is loaded free when you start, up to three months' allowance. Modules (Drafting, Data Rooms Pro, Intake) available on any band.
Pick two or three live matters. Four to six weeks, a fixed fee agreed in writing, your team using it on real work. If it proves itself, you move onto the monthly price for your firm's size and the pilot fee comes off your first invoice. If it doesn't, you walk away and keep everything it found.
