AI and software for law firms

We design and build AI for law firms, notaries and in-house legal teams: search over your own precedents, review assistants that check clauses against your playbook and automation for intake and matter admin. Lawyers review every output, and client files stay in your document management system.

Where the work gets stuck.

  • Knowledge locked in the DMS

    Years of opinions, contracts and memos sit in iManage or NetDocuments, findable only if you remember the client, the matter or the person who wrote them. Associates rebuild work that already exists.

  • Review work that grows with page count

    Due diligence, lease reviews and contract comparisons take hours of careful reading. As more clients ask for fixed fees, those hours become the firm's own cost.

  • Admin around every new matter

    Intake forms, conflict checks, Wwft client due diligence and engagement letters are rekeyed between email, practice management and finance systems before any legal work starts.

How we improve law firms.

Each one is scoped around your systems and rules, and each one keeps a person in charge of the decisions that matter.

  • Precedent and knowledge search

    Lawyers ask a question in plain Dutch or English and get answers from the firm's own opinions, contracts and memos, each linked to the source passage. Search follows the matter security of your DMS, so ethical walls hold.

    Built as custom RAG

  • Contract review against your playbook

    The assistant reads an incoming contract, compares each clause with the firm's or client's playbook and marks deviations with suggested fallback wording. The lawyer accepts, edits or rejects every mark before anything goes back to the other side.

    Built as document processing

  • Due diligence extraction

    Change of control, termination and assignment clauses are pulled from hundreds of data room documents into a review table with page references. Associates verify the table and write the report from structured findings.

    Built as agentic workflows

  • Matter intake and conflict preparation

    An intake form or email becomes a draft matter in Clio, BaseNet or Legalsense, with parties extracted and run through the conflict search. The responsible lawyer reviews the hits and approves the matter before it opens.

    Built as back-office automation

  • Client portal for documents and status

    Clients upload documents, sign through DocuSign and see where their matter stands in one secure place. The secretariat gets fewer calls and emails asking for an update.

    Built as customer portals

  • Testing legal AI before it goes live

    We test legal AI tools against questions your own lawyers have answered, checking that citations exist and quotes match the source. The same test set runs on every change to prompts, models or data.

    Built as LLM evals

Built around the rules.

What we design for from the first week. Your legal and compliance people keep the final word.

  • Professional secrecy and privilege

    The duty of confidentiality under the Advocatenwet and notarial secrecy mean client files must stay under the firm's control. We keep documents and indexes in your environment or an EU cloud region, and use model contracts that exclude training on your data and limit retention.

  • NOvA rules and supplier oversight

    The NOvA expects lawyers to stay in control when suppliers process client files, including cloud and AI providers. We document where data goes, which sub-processors are involved and how access is logged, so your firm can assess it.

  • GDPR and data minimisation

    Legal files are full of personal data, sometimes special category data. We redact where possible, limit what is sent to a model and align retention with your file retention policy.

  • Wwft client due diligence

    Where intake automation touches Wwft checks, the software gathers and records the information, and a qualified person completes the assessment and signs it off.

Works with what you run.

If a system has an API, a database, an export or an inbox, we can build on it. These are the ones we meet most.

Where to start.

Precedent search for one practice group

We start with one practice group, such as corporate or employment, and index its opinions and model documents from the DMS. Lawyers use it on real questions for several weeks while we measure answer quality against their own judgement.
