By use case

Which tool for
which need?

There is no single type of legal AI tool. The right choice depends on the use case, and the risk tolerance.

General legal research, no client files involved

You need case law on a general point of law, without uploading any client documents. Public sources are sufficient.

→ Westlaw or Lexis+ are strong choices for pure research

Analysis of contracts and client case files

You are uploading confidential client documents to analyse them, identify risks, and prepare legal advice or pleadings.

→ LegisBox removes the cloud transfer behind LPP and UK GDPR risk

General drafting on non-sensitive matters

You are drafting template documents, non-confidential analysis, or research notes without sensitive client data.

→ ChatGPT or Claude can be used with caution for general drafting

Full firm AI integration, all workflows

You want AI integrated across all workflows: research, case analysis, drafting, diary management, client portal.

→ LegisBox is an integrated solution that leaves LPP intact
