The choice of language model is not a cosmetic detail: it determines whether the solution fits your type of work. For long-context case files, such as a 500-page deed or a complete litigation file, we typically use Claude because of its 200K-token context: the model reads an entire file in one go and delivers a structured summary without us having to chunk it artificially. For broad contract-review flows with rapid iteration we deploy GPT-4o, which is on balance a little faster on shorter documents. And for firms with the strictest privacy requirements, such as trust offices, M&A boutiques with government clients, or lawyers handling state-secrets matters, we deploy Llama 3.1 fully on-premise or in a private VPC. No outbound API connections, with auditable model weights.
The use cases we build most often, grouped: document review and clause extraction for due diligence, RFP analysis and contract renewal cycles. Case file summarisation for litigation teams taking over a file or preparing a conclusion. Semantic search over case law: not just keyword searching on rechtspraak.nl or EUR-Lex, but conceptual searching, for example: "rulings in which an extension clause in a lease agreement was interpreted in the tenant's favour under ROZ conditions". Client enquiry triage via a chatbot front-end on your website that handles first-line questions and delivers the lawyer a structured summary for the intake meeting. Legislative monitoring that scans the Staatscourant, the EU Official Journal and case law for relevance per client or case, with no more manual alerts.
In addition, we build compliance mapping for client portfolios (GDPR, Wwft, AI Act, CSRD), KYC/Wwft screening for client onboarding and, for firms that advise clients on AI compliance themselves, AI bias audit tooling that the firm uses to assess its clients' applications. Time-recording automation is an underestimated gain: an AI that categorises email traffic, calendar entries and document edits against open cases significantly reduces the administrative burden per lawyer, especially in firms under pressure from billable-hour targets.
Regardless of the use case, the approach is the same: a RAG layer that connects to your own knowledge base, an EU-resident deployment of the model, an audit log that retains every model call with its input and output for review, and a human-in-the-loop design in which a lawyer always has the final check before any output reaches a client.
