Document deluge
A modest commercial dispute easily produces 500–5,000 documents in disclosure. The junior team spends 40–100 hours triaging what is relevant before strategy can begin.
Vertical pack · 30 days · €9,500
AI agents for law firms.
Five agents pre-built for the daily realities of boutique law firms and in-house counsel, case-file summarization, contract review, legal research, client communication, and billing. Customized to your practice in 5 days, deployed in 30, fixed at €9,500. GDPR-compliant, privilege-preserving by design.
What can AI agents do for a law firm?
AI agents in 2026 reliably handle five high-leverage legal workflows: case-file summarization (turning thousand-page case bundles into structured briefs), contract review (clause-by-clause comparison against templates and playbooks), legal research (precedent search with citation tracking), client communication (status updates, document requests, billing inquiries), and billing tracker (time capture, narrative drafting, invoice preparation). Boutique firms typically reclaim 15 to 30 hours per fee earner per month, redirecting that time to billable advisory and rainmaking work. Law firms using AI close routine work 30 to 50 percent faster than firms doing it manually.
theagency47 · Updated May 2026 The problem
Law firms are time-rich on the wrong side of the ledger.
Contract drafting drift
Each contract review touches 10–30 clauses against firm playbooks. Done well, it takes 90 minutes. Done quickly, it misses risks. Done at volume, it crushes margins.
Time capture leaks
Industry studies estimate 15–25% of billable hours never make it onto an invoice because narratives are written days late and partners under-claim.
What you get
Five agents, fixed-price engagement.
Each pre-architected for legal work, customized to your firm's practice areas, software stack, and house style during the 5-day discovery phase.
Agent #1 · Executive tier
Case-File Briefer
Reads case bundles (PDFs, emails, transcripts), produces structured briefs, facts, parties, timeline, key issues, exhibit map, open questions. Drafts an opening memorandum the partner can refine in 30 minutes instead of writing from scratch.

- Citation accuracy: tracked + verified
- Output formats: Word, OneDrive, NetDocuments
- Hours saved: 8–12 per case file
Agent #2 · Operational tier
Contract Reviewer
Compares incoming contracts against your firm's playbooks. Flags deviations, suggests fallback language from your precedent library, drafts negotiation comments. Associates review the flags rather than the whole document.
- Integrations: iManage, NetDocuments, HighQ
- Playbook training: from your existing contracts
- Cycle time: 90min manual → 20min review
- Risk register: maintained per matter
Agent #3 · Executive tier
Legal Research Assistant
Researches points of law across approved sources (firm KB, Westlaw, LexisNexis via approved APIs), produces structured memos with full citations, flags contradictory authority, and tracks recency of holdings.
- Citation discipline: every claim sourced
- Hallucination guard: 3-layer verification
- Recency check: holdings under 2 years flagged
- Output: Word + structured JSON for KB
Agent #4 · Operational tier
Client Communication Drafter
Drafts status updates, document requests, and billing inquiry responses in your firm's voice. Partners review and send in 5 minutes instead of writing from scratch in 30.
- Voice training: from your sent folder
- Privilege markers: enforced in drafts
- Integrations: Outlook, Gmail, Clio, MyCase
- Hours saved: 4–8/week per partner
Agent #5 · Task tier
Time & Billing Tracker
Watches calendar entries, document edits, and email activity to draft time entries with proper billing narratives, then sends them to the fee earner for one-click approval. Closes the 15–25% time-capture leak.
- Integrations: Clio, PracticePanther, Smokeball
- Narrative quality: trained on firm style
- Approval workflow: one-click
- Time recovered: typically 5–10% revenue uplift
Bundle
Privilege-aware operating layer
A coordination layer ensures privilege markers propagate across agents, audit trails are kept for every action, and sensitive identifiers are tokenized before reaching the model on higher-risk flows.
ROI math
The numbers for a 10-fee-earner boutique firm.
| Item | Estimate |
|---|---|
| Pack cost (one-off) | €9,500 |
| Monthly Claude API + tooling | €800–€1,800 |
| Hours reclaimed per fee earner | 15–30 / month |
| Total hours reclaimed (10 earners) | 150–300 / month |
| Blended billable rate (assumption) | €180/hour |
| Monthly billable-equivalent value | €27,000–€54,000 |
| Time-capture leak closure (5–10% revenue) | +€8K–€20K/month |
| Break-even on pack cost | Inside Month 1 |
| Net Year-1 ROI | ~25× to 50× |
Numbers above are illustrative for a typical 10-fee-earner boutique. Your mileage varies with practice area, billing rate, and matter mix. Legal-vertical ROI is consistently higher than accounting or e-commerce because billable rates compound the reclaimed time.
Compliance posture
Built for an industry that lives by privilege.
Zero-retention API calls
All agent calls to Anthropic Claude run with zero-data-retention configuration. Inputs and outputs not retained beyond 7-day API operational logs, never used for model training.
Per-matter isolation
Each matter has its own knowledge base partition. Information does not leak across matters. Conflict-of-interest checks are integrated into the agent access layer.
Privilege markers
All agent-drafted output carries the firm's standard privilege markers automatically. Audit trail logs every agent action with timestamp, input hash, and reasoning.
Tokenization on sensitive flows
For higher-risk workflows, identifiers (names, NIs, account numbers) are tokenized before reaching the model and restored only in firm-controlled output.
GDPR + EU residency
DPA executed before any client data touches an agent. Data residency configurable. SCCs in place for any non-EU sub-processor. We are EU-based.
Bar-association friendly
Designed to fit common bar guidance on supervised use of AI in law practice. Human-in-the-loop preserved on all client-facing outputs. Source documentation available for ethics review.
FAQ
Questions from law firm partners.
What can AI agents do for a law firm?
Five high-leverage workflows: case-file summarization, contract review, legal research, client communication, billing/time capture. Boutique firms reclaim 15–30 hours per fee earner per month.
How much does this cost?
Legal vertical pack: €9,500 fixed for the 5-agent build. Monthly running cost €800–€1,800. ROI typically breaks even inside month 1 because billable rates compound reclaimed hours.
Is client privilege preserved?
Yes, through zero-retention API config, per-matter knowledge-base isolation, privilege markers on drafts, tokenization on sensitive flows, full audit trail, and a tailored DPA. Designed to fit bar-association guidance on supervised AI use.
Will AI replace our paralegals or juniors?
No. AI absorbs the document-review-at-scale and template work that has the lowest margin. Junior roles shift toward AI output verification, exception handling, and direct client work. Adoption frees capacity for higher-value advisory.
Which legal-tech platforms do you integrate with?
Clio, MyCase, PracticePanther, Smokeball, Filevine, Litify, NetDocuments, iManage, HighQ, Lex Machina, Westlaw and LexisNexis (where approved APIs exist), Google Workspace, Microsoft 365, DocuSign.
What practice areas does this work best for?
Commercial / corporate, employment, litigation (document-heavy), real estate, IP. Less proven for criminal defense and family law where eval-friendly bounded outputs are harder to construct.
Can the pack be scoped down?
Yes. If you need only 3 of the 5 agents, we quote a custom Workforce Starter at €7,500. Heavy compliance scoping suggests Enterprise instead.
