The pain you actually feel

Most legal AI was built by people who've never sat in your chair.

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.

Monday · 11pm

You're drafting the 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

Tuesday · 9am

Your cloud AI vendor still has last week's matter content. You can't tell the client where it went.

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

Wednesday · 4pm

Counsel asks if the case has been pressure-tested. You point at notes and a timeline.

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

Thursday · 7am

The SRA wants to see how you used AI on the matter. You hand them a Word doc with bullet points.

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

Friday · before the hearing

You haven't checked the citations against BAILII. Post-Ayinde and Munir, that's a problem.

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

The math

What it's worth, in pounds you're already billing.

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.

All numbers shown are deliberately conservative; your firm's billing rate and matter volume can move them up materially.
Live in production today

Not a roadmap. Running on real matters.

Every claim below runs on the live product. Discovery calls walk through your actual matters — not a demo deck.

Adversary Pass · Always-on

Thirteen lenses running as the draft forms.

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.

Reasoning Ledger · HMAC-SHA256

Every model call. Chain-linked. Signed. Exportable.

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.

Pricing

May launch rate. Locked for life.

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.

May launch rate · through 31 May
£500
per fee earner / month · locked for life
67% off list. Locked while subscribed. May lock-ins also receive the signed reasoning ledger as a lifetime cohort gift — the only place outside Enterprise (£2,400/seat) where the ledger appears.
Regular Practice rate
£1,500
per fee earner / month · list price
What new customers pay once launch pricing ends (1 August 2026). Same product, same modules — without the signed reasoning ledger, without the launch discount, no lifetime lock at the lower rate.
For a 5-fee-earner firm: lock today at £500/seat/mo and save £60,000/year, every year, for the life of your subscription. That's the difference between the May launch rate (£30,000/yr) and the regular Practice rate (£90,000/yr) — compounding for as long as you stay.

Human in the loop · always
AI drafts. Solicitor reviews, edits, signs. Never autonomous. Every output ends at the fee-earner's signature — that's the Principle 7 evidence the regulator wants, and the discipline the buyer wants.

Try it on a real matter. Before you sign anything.

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.
