Legal Evidence OS
Case materials,
in a structure where the evidence shows.
Legal Evidence OS turns scattered documents and records into a case-preparation structure that experts can verify — linking facts, sources, claims, and review status.
We do not provide legal judgments or predictions of success. Important decisions must be reviewed by qualified professionals.

Why Legal Evidence OS
Collecting files and
understanding a case
are not the same.
Case preparation needs more than document storage — it needs a structure that explains which record supports which fact, and how that fact connects to claims and issues.
Broken context
Missing links between facts, sources, and claims
Repeated rework
Timelines and lists rebuilt for every review
LEOS does not judge your materials for you. It clarifies the source and status of each record, creating a foundation for people to review more accurately.
Core capabilities
One workspace where
the evidence stays connected
From basic case information to original evidence, chronology, claims, and review status — everything is linked in one structure. Every feature shares one standard: never lose the source.
01Case · People · Assets
Structured case information
Manage cases, people, entities, assets, lawsuits, and judgments as interconnected records.
02Fact · Source · Status
Source-centered fact records
Attach documents, page locations, authors, and verification status to every important fact.
03Date · Event · Context
Full timeline
Organize the flow of the case — from exact dates to months, years, ranges, and estimates.
04Original · Evidence · Link
Evidence storage and links
Separate originals from derivatives, and show which claims and issues each item supports.
05Request · Review · Approve
Review collaboration
Divide data entry, review requests, change requests, and completion status by role.
06Summary · Citation · Review
Review-ready organization
Compile case summaries, chronologies, claims, and evidence into source-cited review materials.

Hand off in reviewable form
Create a case summary with traceable evidence as the starting point for expert review.
One record, three roles
Clients and professionals work together
on one case record
Clients structure the record; lawyers take on litigation cases and patent attorneys take on patent & trademark cases for review. All three roles share the same source-backed record on the same screens, so nothing is lost in the handoff.

No referral fees — we provide review tools (seat subscriptions), never paid introductions.
Trust by design
Ground rules for a product
that handles sensitive records
We design for sources, permissions, and human review before convenience. AI is limited to a tool that assists review — never a substitute for the record.
Facts separated from analysis
User input, document contents, human opinions, and AI analysis are never treated as the same kind of fact.
Originals and sources preserved
Originals, derived files, and citation locations stay distinct so evidence can always be traced back.
Per-case access control
Permissions are checked on the server by organization, case, object, and scope of work.
Humans make the final review
AI output is only a review candidate — legal conclusions and important decisions are never auto-confirmed.
