What it is

Our own system: a plain-English method, rules and checklists that make AI-assisted legal work verifiable before it reaches a client or a court.

Any lawyer or firm using AI on real work who needs to stand behind every line.

Fourteen ready-made Rules, one per legal task
Six one-page checklists (memo, contract, advice, update, filing, confidentiality)
Three procedures: new matter setup, draft→verify→sign-off, model-update review
The authority ledger and AI-use register
Confidentiality pack and disclosure wording

Plan	Price	What you get
Free handbook	$0	The method, the seven failures and the checklist.
Pro handbook	$99	Rules, checklists, procedures, confidentiality pack.
Firm build	$4,500+	We build it inside your environment.

Indicative; enterprise prices on request. Confirm on the vendor's own page.

Runs inside your own account or a local model, so client data never leaves your control. The method also teaches exactly what to redact and record.

The layer that makes everything else safe: the verification step you add to whatever AI tools you choose. It is how you answer 'how do you know?'.

Alternatives: (the method itself).

Our free handbook shows you how to check every citation before it leaves your firm.
