Legal proof
deserves structure.

AI that understands your documents, connects evidence to conclusions, and builds proof trees you can actually trust.

Structured reasoning Evidence chains AI-powered documentation Structured reasoning Evidence chains AI-powered documentation

Legal work runs on documents. Contracts, evidence, case files, disclosures — each one a piece of a larger story. But when those pieces live in emails, shared drives, and scattered tools, the structure that matters gets lost. The proof chain breaks. The reasoning becomes invisible.

ProofTree restores that structure. It reads your documents, understands their relationships, and builds an AI-verified proof tree connecting evidence to conclusions. Structure that holds up in court. Reasoning you can show, not just describe.

Evidence at the center.
Inference in the open.

Document Intelligence

Reads and understands legal documents — contracts, evidence logs, case files — and extracts the relationships between claims, facts, and conclusions.

Proof Tree Generation

Builds structured proof trees connecting evidence to conclusions, making the logic of your case visible, shareable, and auditable — not buried in prose.

Structured Reasoning

AI-powered inference that traces how each document supports each conclusion, so nothing gets lost between the evidence and the argument.

The product

Not another document summary tool.

Most AI legal tools read your documents and give you a summary. ProofTree goes further — it reads your documents, understands how they connect, and shows you the proof structure that follows from them. A contract clause connects to an obligation. An obligation connects to a breach. A breach connects to a damages claim. That chain is the proof. That's what ProofTree builds and maintains as your case evolves.

Every legal argument is a proof. Most tools help you write the argument. ProofTree helps you build the proof.
