The office work of a law firm, now handled by AI.

EST. 2025 — AI PRODUCTS FOR LAW FIRMS & LICENSED PROFESSIONALS

An AI that has memorized everything about your practice takes on document drafting and daily clerical work. We're a startup building AI products for licensed professionals — lawyers, labor & social security attorneys, administrative scriveners, and more.

From family register & interview notes
Company

Built from inside the industry.

Our founder's mother is a lawyer. Having grown up watching the daily reality of a law office up close, we design from real friction on the ground and build whatever we need in-house. We're shaping AI for licensed professionals, one piece at a time.
