Private AI for Law Firms

How can law firms use AI without risking client confidentiality?

Keep the AI on hardware the firm controls, so client documents never leave the network and no outside vendor sees the prompts.

The Massachusetts Rules of Professional Conduct expect lawyers to make reasonable efforts to prevent unauthorized disclosure of client information. Public AI tools may log prompts and store uploads outside your control, and one associate pasting a draft agreement into a chatbot is enough to create a problem.

Our page on private AI for law and accounting firms covers professional firms in general. This page is legal only: confidentiality, privilege, matters and the way law offices actually work.

Does using AI put attorney-client privilege at risk?

It can, if privileged material is shared with a third-party service whose terms allow it to be stored, reviewed or reused.

Whether a given use affects privilege is a legal question for your firm and its ethics counsel, not your IT provider. What we can do is take the third party out of the picture. On a private AI server, privileged documents are indexed and queried on the firm’s own machine, nothing is used to train anyone else’s model, and the firm keeps the logs.

What can a law firm do with private AI?

Private AI lets attorneys and staff search, summarize and question the firm’s own files in plain English.

• Surface prior work product and precedent across years of matters
• Find specific clauses or terms across contracts and agreements
• Summarize deposition transcripts, long correspondence and discovery documents
• Speed up routine document review
• Answer questions about firm procedures and policies

Answers are grounded in your own documents, so an attorney can check the source instead of trusting a guess. Every output still needs a lawyer’s review.

Can private AI keep matters and ethical walls separate?

It should, and we plan access so people reach only the document sets their role and matters allow.

We decide with you which folders go into the AI and which stay out, and set up separate document collections where ethical walls or client restrictions call for them. If your firm runs a document management system, we can assess how to bring its contents in and work with your DMS vendor where needed.

How does a Boston law firm get started with private AI?

Start small: one NVIDIA DGX Spark, one practice group’s documents and a trial period of real use before widening it.

The server sits in a secure room or server closet. We connect it to your network, load the chosen documents, set access and onboard staff. Our IT support for law firms keeps the surrounding systems, backups and storage in shape, including IBM FlashSystem for firms that want enterprise-grade protection for case files.

We work from our shop at 335 Auburn Street in Auburndale (Newton), on-site across Greater Boston, and remotely. The Massachusetts side, including your WISP under 201 CMR 17.00, is handled by our IT compliance services. For the hardware itself, see private AI server setup.
