The AI Thinking Partner for Lawyers Who Do Not Have Time to Type

Legal work happens fast and thinking is done verbally — in hallways, before hearings, between calls. AI tools that require typing slow this down and forget the matter context every session.

TLDR:Lucy OS1 remembers your matters and client context between sessions. Brief yourself on a case by voice, talk through strategy, and capture key decisions — all without opening a separate application. Try Lucy OS1 for free — no credit card required.

Frequently Asked Questions

Is Lucy OS1 trained on legal data?
Lucy uses GPT-4o, which has general legal knowledge from training data. It is not a specialised legal research tool and should not replace proper legal research. Its value for lawyers is as an organisational and thinking partner for matters you share with it, not as a source of legal authority.
Is client information safe with Lucy?
Lucy is Swiss-hosted with end-to-end encryption and a zero-data-retention voice processing policy. However, lawyers should evaluate Lucy OS1 against their bar association's guidance on AI tools and client confidentiality before storing client-specific information.
