AI for law firms

When you bill by the hour, an hour saved becomes an hour you can bill. On a fixed fee, it becomes margin. We identify the firm's unbilled time, measure it in hours per week per lawyer, and eliminate it, without ever putting a client file into a consumer AI tool.

TL;DR

Who it's for: law firms with 1 to 50 people, including lawyers, associates and assistants.What we do: an audit of your processes, training for your team, then custom tools if needed.How we measure it: hours recovered per week per lawyer, billable or converted into margin.Data: no client file in a consumer AI tool, models hosted in the European Union, and what leaves the firm agreed in writing before any tool goes live.

The problem / 01

Your firm sells advice and representation, but some of its hours are never billed.

The five tasks we see in almost every law firm:

  • Reconstructing time spent from memory at the end of the week, with hours that will never be recorded.
  • Reading, sorting and summarizing documents in a large case file before work can begin.
  • A clause or argument already written for a previous matter that you can no longer find.
  • Letters, formal notices and draft submissions written from scratch.
  • Following up with clients for missing documents and retainers.

We work on site around Marseille and Aix-en-Provence, and remotely throughout France.

AI prepares, the lawyer decides. Nothing is sent to a client, another lawyer or a court without human approval.

Method / 03

Three steps, in this order.

/ 01

An audit of your processes:

We observe how the firm actually works, lawyer by lawyer, assistant by assistant. You leave with a quantified roadmap: every task identified, the hours recovered each week and how to eliminate it. You can put it into action yourself or work with us: the choice is yours.

/ 02

Training for your team

One day working with anonymized files from your firm. Lawyers and assistants learn to use AI for everyday tasks, and above all what they must never share with it.

/ 03

Custom tools, if training is not enough

Connected to your existing tools: practice management software, email and document management. We do not replace your software: we remove the manual work that still surrounds it.

Data / 04

Your data and legal professional privilege.

A lawyer's duty of professional secrecy is a matter of public policy: it is general, absolute and unlimited in time (Article 66-5 of the Act of 31 December 1971 and Article 2 of the National Rules of Procedure). It is the first constraint in every project, not an option.

What leaves the firm

Only the text to be processed, pseudonymized whenever the client's name is not needed, sent to an AI model hosted in the European Union through a professional account that prohibits training on your data.

What never leaves

Your complete case files, your access to RPVA and court platforms, your billing data, and anything you classify as sensitive.

How it is protected

Individual access for each lawyer and assistant, every consultation logged, and no copies stored by us. A GDPR data processing agreement and the firm's AI policy are signed before the tool goes live.

Transparency

The suppliers used and the location of their servers, in the European Union, are set out in the scoping document. You approve them before the tool goes live.

Training / 05

AI training for lawyers and associates.

In March 2026, the French National Bar Council adopted a guide on professional ethics and artificial intelligence. Our training uses anonymized files from your firm, with a section dedicated to professional secrecy: what you can paste into a tool and what you must never paste.

FAQ

The questions we hear all the time.

Only the text you choose to share with it, pseudonymized when the client's name is not needed. Your complete case files stay within the firm. Access is through a professional account hosted in the European Union that prohibits training on your data.

Before anything is sent, names, addresses and numbers that identify a person are replaced with codes. The AI model works on the coded text, and the mapping between codes and identities never leaves the firm.

No. We connect to it or work alongside it. The goal is to eliminate what is still done manually around your software, not to replace it.

When billing by the hour, we start with time you are not billing anyway: sorting documents, searching your archives, forgotten hours and follow-ups. On a fixed fee, every hour saved becomes margin.

It depends on the number of tasks to address and the size of the firm. We work out the figures with you after an initial 30-minute conversation, before you commit to anything.

You receive the roadmap at the end of the audit. Allow another 3 to 6 weeks for the first task to disappear.

Yes, as long as a task repeats every week. The scope changes with the size of the firm, not the method.

No. The tool prepares, the person checks and decides. We remove the tasks your team has to endure so they can spend more time on cases.

We start with their own tasks, not the tool. When a team member sees a task they hate disappear, that reluctance soon fades.
