“They just get it.” Senior criminal KC
Who we work with
Law firms, chambers and individual practitioners.
Every session is designed and delivered by Chris Jeyes, a practising barrister and former law-firm partner.
What we do
Training, governance and the systems behind them.
Most clients start with training, add governance once the basics are in place, and come back for the systems their practice needs.
Beyond training
Systems we build to order.
Built first for cross-examination, and adaptable to any work that is done out loud.
Also: AI Strategy — for individuals, firms, chambers and businesses across England and Wales.
Sound familiar?
You didn't become a lawyer to do admin.
Your skills are exceptional. Your time should be spent on work that matters — not drowning in the mundane.
The weight of the work
Incisive cross-examinations and finely-honed submissions — but also mountains of material to wade through, summaries to write, schedules to prepare. Evenings and weekends lost to preparation. Parents' evenings missed.
Regulatory uncertainty
AI obligations are evolving fast. The spectre of compliance failures, disciplinary proceedings, and Hamid hearings looms large. Using new tools without proper guidance puts your practising certificate at risk.
The pace of change
Colleagues are adopting AI. Clients expect more for less. The profession is shifting beneath your feet. Standing still is not an option — but moving without proper guidance is reckless.
It doesn't have to be this way.
I think it is imperative to build bridges in the legal community between the AI sceptics and the AI enthusiasts. There is no real choice about whether lawyers and judges embrace AI — they will have to — and there are very good reasons why they should do so — albeit cautiously and responsibly, taking the time that lawyers always like to take before they accept any radical change.

How an engagement runs
How we work.
Each stage ends with something in writing that you keep.
Find out where you are
A short survey or a few conversations with partners and practice groups, so the training is built on the tools your people use and how they use them.
Train and set up
Sessions by practice group, hands-on, on fictional matters in your areas of work. Where the engagement includes it, tools are installed and configured on your own machines.
Make it stick
Written guidance for the firm, champions where the programme includes them, and a review after 90 days.
Frequently asked questions
Common questions answered.
Start with training.
