Lexis Labs · University of Cambridge · lawyer-in-the-loop infrastructure
An engine that turns regulated client intake into verified, source-traced case files, and leaves every conclusion to a professional. Born at the University of Cambridge. Live in production today.
01Origin
At the University of Cambridge, our founding team came together through three separate winning projects at the Hack the Law hackathon, each judged by the firm that set the challenge. Each solved a different piece of the same problem. We merged the strongest elements into one lawyer-in-the-loop platform under Lexis Labs Pty Ltd.

Challenge Winner02The technology
Legal requirements encoded as deterministic, versioned rule packs: pure functions that run, and are tested, with the LLM switched off. Adding a new legal domain is legal research, not engineering: a rule pack is a data file.
Every fact on a file is traced to a client utterance or a source document. Claims and citations are verified against structured rules and registers. Nothing is unexplained.
When regulation changes, the rule pack changes, and every past check stays auditable against the version it ran on.
The software never concludes. Conclusion words are banned from client-facing output, and unit-tested to stay banned. Everything requiring judgment routes to a professional, who reviews, edits and signs.
The engine collects supporting documentation, structures the enquiry, and drafts the onboarding file and report. The lawyer edits, decides and signs.
Deploys on-premise or in the firm's controlled infrastructure; client data never leaves the firm. We share the method, not the data.
All legal advice, compliance decisions and client acceptance remain with lawyers. By design, not by disclaimer.
03Proven in production
A 15-minute conversation becomes a verified case file.
The engine is live end to end on UK immigration intake. Every requirement traced, checked and priced before a lawyer touches the case. Not a prototype; a running system.

Conversations with firms since the hackathon revealed where the engine belongs first.
Better-prepared enquiries, structured before they reach a fee earner.
The checks required under EU AMLD (ZPPDFT-2 in Slovenia) run as a rule pack: document collection, register checks and the compliance file automated, with the professional signing acceptance.
A visa route, an AML check, a conflict check: each is a data file to the engine, not a rebuild.
“Onboarding is our heaviest untouched admin burden.”
