What it looks like in practice
A client asks about a penalty clause in a 2022 contract. The attorney spends 20–30 minutes searching folders and reading. One question, one expert, half an hour gone — at €80/h that is money lost on admin.
The attorney types the question. In 47 seconds the AI returns the exact clause, paragraph number, and full text — sourced from your own archive, data never leaving your office.
ROI Breakdown
| Metric | Before AI | With AI | Monthly Impact |
|---|---|---|---|
| Document search time per question | 20–30 min | < 1 min | −95% |
| Standard pleading draft | 1–2 h | 10–15 min | −80% |
| Hours recovered / attorney (at €80/h) | — | ~20 h | up to ~€1 600 potential billings |
| Where case files and queries go | Cloud AI provider's servers | Only the firm's own network | Fewer parties with data access |
| Potential additional revenue (3 attorneys) | — | — | up to ~€4 800 / month |

Document search in seconds, a draft in 10–15 minutes (the attorney reviews and finalises it), full archive searchable by every team member.
Automatic contract risk analysis on intake, legislative change monitoring for active cases, e-signature integration.
New revenue model: fixed monthly legal retainer for SMEs — AI handles routine queries, attorney handles strategy. Same team, room for more clients.
Professional secrecy and file security
Attorney–client confidentiality
Lawyers may use AI tools, but they remain responsible for protecting confidential client information – including when they entrust it to an external provider. With a local system, files and queries are processed inside the firm's network, so you don't have to assess a cloud AI provider's terms and server locations.
Who sees which documents
Access is role-based: you can create separate document collections for teams or matters and decide who can use them. If 3oz services the system remotely, we sign one clear data processing agreement with you.
AI drafts, the lawyer decides
Answers and drafts are working material. The system points to the source document, and a lawyer always reviews the final text. Uses like search and drafting usually fall under the limited or minimal risk categories of the EU AI Act.
Frequently asked questions
Do we have to change the software we use?
No. The AI assistant runs alongside your legal research and practice management tools as a separate browser window. We load selected folders with case files and templates into it.
Can the AI make mistakes?
Yes, like any language model. That's why the system shows the passage and document its answer is based on, and drafts are always reviewed by a lawyer.
Can we use the assistant outside the office, e.g. in court?
Yes. You connect through an encrypted network (Tailscale), without exposing the firm's server to the public internet.
How does a deployment start?
With a free 30-minute consultation. We identify which tasks take your team the most time, then propose a hardware setup and the scope of the first phase.
