Four reasons firms choose us
Choose to stay off the cloud
Client information and matter records can remain on your Mac. Designed with maximum regard for confidentiality — unlike generic cloud services.
Battle-tested — we've run it daily for over a year
We do not deliver what we do not run ourselves. Failure modes and operational pitfalls are already mapped, so post-deployment surprises do not happen.
Custom-built for your firm — not a generic AI service
Generic AI services like ChatGPT cannot reach your firm-specific folder structure, intake rules, and shortcuts. We build them to fit your practice.
Designed to prevent AI hallucination
Every AI answer is accompanied by the exact source in your vault (file name and page number). Answers without a source are not surfaced, so the output is reliable enough for business decisions. The premium statute-search option adds a strict mode that quotes official government data verbatim.
