The Problem
A 9-lawyer commercial firm in central London was watching its margins erode under the weight of non-billable work. Lawyers were spending 8-12 hours a week each on tasks that didn't bill: reviewing routine NDAs, summarising lengthy contracts for partners, doing first-pass intake calls with new prospects, and chasing missing documents from clients.
The managing partner had been told by a Big Law cousin that AI would "take their jobs." The reality, after running the numbers, was the opposite. AI could give them back their highest-margin hours.
What I Built
A precision-targeted automation suite focused on the non-billable work, not the legal advice itself:
1. Contract review assistant. A lawyer drops a contract into a OneDrive folder; within 90 seconds they receive:
- A markup highlighting clauses that deviate from the firm's standard terms
- A risk summary (top 5 concerns, ranked)
- Suggested redlines
- Comparison to similar past deals from the firm's matter database
The lawyer reviews, accepts/edits, and sends. What used to be 90 minutes of first-pass review becomes 15 minutes of senior judgement.
2. Intake automation. Prospective clients book via a smart form that, before the call, sends:
- A targeted intake questionnaire (different per matter type)
- Document upload links
- An automated pre-call summary delivered to the partner
By the time the partner calls, they have the conflict check done, key facts on screen, and a draft engagement letter ready to send. Intake calls dropped from 45 minutes to 18.
3. Document chase workflow. When a matter is missing required documents, the system auto-emails the client at days 3, 7, and 14 with a personalised reminder and a secure upload link. Status reports go to the partner; no human follows up unless the automation fails.
4. Time capture suggestions. A daily AI assistant reviews each lawyer's calendar + email + document edits and suggests time entries. The lawyer approves or edits. no more reconstructing the week on a Friday.

Outcome
The firm added roughly £480K of annualised billable capacity without hiring. The managing partner used the savings to fund a junior associate's training programme and to drop one of two paralegals. who left with a referral to a friendly firm and a glowing reference. Lawyers are happier doing legal work instead of admin; client satisfaction scores are up because turnaround time on routine matters dropped.
