An AI matter workspace built for English & Welsh solicitors. Engagement letters in 30 seconds. Adversary pass running on every draft as it forms. Privileged content stays on your laptop — we have no server copy.
It's Monday. 11pm. The hearing is Friday. Your AI vendor still has last month's matter content sitting in their logs. The citation check is on tomorrow's list. The bundle is due by 4pm. You're drafting an engagement letter for the third time this quarter.
Avantwerk drafts it in 30 seconds — SRA-compliant, jurisdiction-correct, in your firm's voice. The clauses you'd type from memory are already there: scope, fee basis, complaints procedure, data handling, governing law. You review, edit the partner-judgment calls, sign.M1
Browser File System Access API. Privileged content lives on the solicitor's laptop. We have no server copy. Egress to AI provider — soft-warn with logged consent. Egress to CRM, email, anywhere else — hard block. Your Principle 7 evidence is the runtime, not a policy paper.M4
Thirteen-lens adversary pass running continuously. Limitation, disclosure, privilege, witness reliability, settlement leverage, costs exposure, contradiction surface. The self-audit opposing counsel is about to run — except it's been running since the matter opened, in sync with every fact you've added. Zero-LLM cost via the reconciler.M9
HMAC-SHA256 signed reasoning ledger. Every model call, every prompt fingerprint, every cost — chain-linked, daily UTC seal, tamper-detection on every entry. Export the matter ledger as one DOCX. The regulator walks through your AI use as evidence, not as a question.M12
Citation verifier at draft-export. Every AI-cited case checked against BAILII before the draft leaves the matter folder. Hallucinated citations stop at the gate. Real ones land with the verification record on file.M10
At 10 matters per fee earner per month, Avantwerk recovers an estimated 41.7 hours of fee-earner time. Per fee earner. Per month. At your Grade C London Guideline Hourly Rate — verified against the 2026 judicial schedule — that's what it adds up to.
Every claim below runs on the live product. Discovery calls walk through your actual matters — not a demo deck.
Opposing counsel's strongest counter, judge's credibility concerns, regulator's principle gaps, costs / limitation / disclosure / privilege / evidence / insolvency / witness reliability / settlement leverage / contradiction surface.
The self-audit opposing counsel is about to do anyway — except it ran two hours ago, before you sent the draft. Zero-LLM cost via the reconciler-as-continuous engine.
When the SRA shows up for a Section 44 visit, you export the matter ledger as one DOCX. The processing chain walks them through your AI use as evidence, not as a question.
No competitor in the UK market ships this. May lock-ins receive it as a lifetime cohort gift — otherwise Enterprise tier (£2,400/seat) only.
The browser File System Access API gives Avantwerk access to your matter folder — but we have no server copy. Egress to AI provider is soft-warn with logged consent. Egress to anywhere else: hard block.
Post-Ayinde and Munir, this is your Principle 7 evidence — runtime, not policy.
The regular Practice rate is £1,500 per fee earner per month. Through 31 May 2026, the launch rate is £500 — 67% off the list price, locked for the life of your subscription. After May, launch pricing tapers month-by-month and ends 1 August 2026 — at which point the list rate applies to all new customers.
The populated demo runs on a fictional matter — Edwards v. Lockwood Properties — so you can click around and feel it before committing. The 7-day trial runs on a real matter from your firm. Bring your own AI provider key. No card on file. Walk away on day 7 with no follow-up if it doesn't fit.
