You’ve already written this brief.
You just can’t find it.

Your best work is buried in folders nobody searches

Every firm has years of winning briefs, persuasive motions, and sharp legal arguments scattered across shared drives. When a new matter comes in, attorneys start from scratch instead of building on what's already been won.

BriefBank turns that dead knowledge into a living, searchable resource your whole team can draw from.

Connect your firm's documents, ask real questions, and get answers grounded in your own work.

Step 1 · Connect

Bring your firm's files where they already live

Upload files directly, or connect OneDrive or SharePoint.

Step 2 · Build

Turn a folder into a searchable library

Name it, scope it to a matter or firm-wide, done. BriefBank indexes automatically and keeps it in sync.

Step 3 · Ask

Ask in plain English

"How did I argue the dog-sniff extension in my earlier Rodriguez memo?" — the way you'd ask a colleague, not a keyword search.

Step 4 · Answer

Get cited answers, grounded in your own work

Answers arrive with inline citations to the exact passages in your library. No hallucinated cases, no invented facts.

Step 5 · Verify

Click any citation, see the exact source

Every answer traces back to the passage that supports it. Every case name and pin cite is verifiable in one click.
