What is the “Why does an AI prompt library leak attorney-client privilege the moment a lawyer uses it?” problem in 2026?
Solo and small-firm lawyers want to use ChatGPT / Claude on case prep but every shared prompt template assumes pasting client facts, blowing privilege.
Who has this problem?
US and Indian solo + small-firm lawyers (1-15 attorneys) who already use AI ad-hoc but worry about confidentiality.
Recorded source context
Dataset source note: I use Claude for first-draft motions. I have no idea what 'do not train on my data' actually means in practice.

- No one: Ships a privilege-aware prompt library + on-device redaction layer for solo + small firm at $49/mo.
What existing players are missing
A privilege-respecting AI workflow: redacts client identifiers locally, runs against any LLM, returns un-redacted to the lawyer. Sells at solo-firm pricing.
