Plexolegal. Legal AI case intelligence for UK claimant law firms.
Hundreds of pages become a triaged case. a cited chronology. a one-page review. a first draft.
What your team gets
Six capabilities built around the work claimant firms actually do, activated as modules and configured to your practice area.
Case Triage
Every new file is read on arrival. Documents are classified, scanned pages become searchable text, and the matter lands triaged, indexed and ready to work before anyone opens a lever arch file. Unclear pages are flagged for human review, never guessed.

Record Intelligence
Medical records, employment files, expert reports, correspondence. Back comes a chronology with every entry referenced to its source page, key dates and parties extracted, gaps in the records highlighted. Hours of reading becomes minutes of checking.
Case Reviews & Valuation
A one-page review for any matter: liability and causation assessment, evidence outstanding, limitation status and a preliminary valuation range. Always a starting point for the fee earner's judgement, never a substitute for it.
Firm Command
A daily briefing of what needs attention, and firm-level views built for hundreds of live matters: limitation dates inside six months, files going quiet, missing records, matters ready to settle. The whole book, without opening dozens of files.
Drafting & Letters
First drafts in your firm's house style, from your own templates: letters of claim, client updates, witness statements built through guided questions. Sent letters are tracked and follow-ups are chased, and every draft is approved by your team before it goes anywhere.
Lexi
Not a chat window bolted to the side. Lexi navigates the platform herself: ask about a matter by voice or text and she opens the case, walks the file and answers with citations you can check against the bundle. The same approval rules apply; speech changes the speed, not the safeguards.
Clinical precision, in digital form
A working preview, shown with illustrative data.
"It never asks for trust. Every point is cited; anything unevidenced is flagged, not asserted."
Integration without friction
Plexolegal is designed as a secure layer that sits alongside your existing case management system. Nothing changes in how your team runs matters day to day.
Your system stays the master
Documents flow in and out through a supervised shared folder that works with leading UK case management setups. Approved outputs return filed per matter, ready to attach.
AI proposes, your team approves
Every chronology, review, draft and follow-up is validated by a fee earner before it enters the case file. Nothing happens without a human yes. That rule never bends.
Auditable trail
A permanent record of how every summary and finding was derived from the original bundle, retained for seven years.
Built around your teams
Permissions, templates and workflows are configured to however your teams are structured, not the other way around.
Client data, treated like client data
Built for firms whose regulator, insurer and conscience all ask the same questions. Plexolegal runs on enterprise infrastructure independently certified to SOC 2 and ISO 27001. A Data Processing Agreement and a firm-specific DPIA are part of onboarding, and our sub-processor list is available on request.
Shaped by working firms, not focus groups
Version one is being built hand in hand with a founding firm specialising in industrial disease, with clinical negligence and professional negligence modules in build. A small number of founding places remain for claimant firms in adjacent practice areas.
What founding partners receive
Preferential terms locked in for as long as you remain a customer, exclusivity in your region and practice area while your module is shaped, and direct influence on the roadmap through a quarterly partner council.
What we ask in return
Real-world input: anonymised historic files to validate accuracy against, examples of your house style, and an hour each quarter on what should be built next. Your practice shapes the product.
Frequently asked
What is Plexolegal?
Plexolegal is a case intelligence platform for UK claimant law firms. It triages new files on arrival, reads the case file (records, reports, correspondence), builds chronologies cited to their source pages, produces one-page case reviews, watches limitation dates daily and drafts documents in the firm's house style. Lexi, the agent inside the platform, answers questions about any case with citations. Fee earners approve everything; the platform never acts alone.
Who is it for?
Claimant law firms in England and Wales running document-heavy caseloads. Version one is being shaped with a founding firm specialising in industrial disease, with clinical negligence and professional negligence modules in build, and the platform is configured to each firm's practice area rather than fixed to one.
Is Plexolegal a legal AI software product?
Yes. Plexolegal is legal AI software built specifically for UK claimant law firms, in the category sometimes called AI legal software or litigation AI. It differs from general-purpose AI tools in three ways: it is grounded in the firm's actual case files rather than the open internet, every answer carries a citation back to the source page, and a fee earner approves every output before it enters the case file.
How does it deal with AI hallucinations?
The platform is built on the assumption that unverified AI output is worthless in law, so it never asks for trust. Every chronology entry, finding and answer carries a citation back to the source page it came from, dates are held against the file and the limitation rules that govern them, and anything the platform cannot evidence is flagged for human review rather than asserted. A fee earner approves every output before it enters the case file.
How does it handle scanned or handwritten records?
Scanned and photocopied pages are converted to searchable text before any analysis. Unclear passages are flagged for human review rather than guessed, and genuinely illegible handwriting is marked as such, never silently invented.
Does it cite the original source material?
Yes. Every chronology entry, review finding and valuation point references the bundle page it came from, so checking any claim against the original document takes seconds.
Where is our data processed, and who can see it?
All processing and storage happens exclusively in UK and EU regions on enterprise infrastructure independently certified to SOC 2 and ISO 27001. Each firm's data lives in its own isolated environment, protected by enforced multi-factor authentication and a complete audit trail, and it is never used to train AI models. A Data Processing Agreement and a firm-specific DPIA come as standard.
How do we get started?
Email [email protected] and ask for the founding partner pack. Founding firms receive preferential terms locked in for as long as they remain customers, exclusivity in their practice area and region while their module is shaped, and a quarterly council that directly steers the roadmap.
