Find1

Search documents, emails, transcripts and notes in one place: by person, date, figure or phrase. A 4GB mailbox archive is ten minutes' reading.


Ask2

Question the matter in plain English. Every answer carries footnotes to the exact page, and Tristum finds where the other side's documents contradict each other.


Data rooms3

“Everything evidencing acceptance, for counsel.” An ordered, watermarked bundle with a contents list, share link, expiry and audit trail — in minutes.


Chronologies4

A cited timeline of the whole matter, built from every source, exportable straight into pleadings.


Witness statements5

First drafts assembled from the file, every factual paragraph carrying its source, PD 57AC-aware. The human always signs; Tristum assembles.


Quantum6

Schedules of loss built from the evidence: every figure footnoted, interest to any date, out to Word or Excel. Point it at their schedule and it checks every number.


Your matters never share a machine.

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.

i

Your firm's own server

A dedicated UK server per firm. No shared infrastructure, no other firm on the machine. Segregation a managing partner can explain to a client in one sentence.

ii

Read-only, always

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.

iii

Citations as compliance

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.
