01What lives here
Three things
A practice brain is a prefrontal cortex for your practice — the part that holds everything so you do not have to. Every matter, every party, every date, every note, kept in one place on your own computer and still there when you come back to it. There is one edition per jurisdiction. Alongside them, a handful of tools that each do exactly one job, and a weekly newsletter on Indian data-protection and AI-governance law.
02Latest issue
It predicts the next word. That is the whole machine.
THE PRIMER starts here — a weekly strand that explains how these systems actually work, from zero, for lawyers who will have to advise on them. Part 1: what a language model is, why anyone built a next-word guesser in the first place, and why invented citations are a structural property rather than a bug. Plus a word-by-word audit of the DPDP Act showing the entire GDPR Article 22 vocabulary is absent from it, and the IT Amendment Rules 2026 that have been binding AI law in force since 20 February.
03The posture, stated precisely
Stated one fact at a time, so each one can be checked
- There is no server of mine. No accounts, no telemetry, no analytics, no crash reporting, no backend. I do not receive your data because there is nowhere for it to arrive. That is a fact about my infrastructure, and it holds unconditionally.
- Your files stay on your machine. Your matters and your papers, audit logs and configuration live only in your own home directory, in a local database you can copy to a USB stick. I cannot read that folder.
- You bring your own key. Where a cloud model is used, it is reached through your account on your credentials. There is no shared key, no middleman account, and no request of yours passes through anything I operate.
- Pseudonymisation runs on every outbound request. Names, government identifiers and case references are replaced before the prompt leaves your computer, and restored in the reply you read. It is wired through a single function that every cloud call passes through, and it is covered by tests — not a mode you could forget to switch on. How the swap works →
- It is a safeguard, not a discharge. Pseudonymisation reduces what is exposed. It does not perform your cross-border transfer assessment, obtain your client's consent, or answer to your regulator for you. What each jurisdiction still requires →
- NAKASHA is the strict case. It ships with no network entitlement at all, so it cannot reach the internet even if it wanted to — the operating system refuses on its behalf. Where a claim can be made absolute it is made absolute; where it cannot, it is not.
- The source is published so every sentence above can be verified by you, or by anyone you ask to check, instead of taken on trust.
- One exception, disclosed. The newsletter form sends your email address to Buttondown, which delivers the issues. Nothing else on this website collects anything from you, and every issue can be read without subscribing.
04Who publishes this
One advocate, building in the open

Most of what is here exists because a solo practitioner has no back office. The work that a junior or a clerk would absorb in a larger chamber — finding your matters in tomorrow's board, keeping citations straight, remembering what a file said three months ago — is the work these tools take on. They do not do the part that needs a lawyer.
