Every contract
reviewed.
Every cent tracked.

M&A due diligence involves hundreds of contracts. The AI that reads them has a measurable cost per document. P402 makes that cost visible, governed, and settled onchain: per contract, per clause, per model tier.

P402 does not provide legal advice or final judgment. Routing observations (Flash vs Pro complexity) are descriptive measurements of the demo run, not recommendations.

01The Problem

Legal AI has a cost attribution problem.

Legacy
Operating cost per document in the legacy workflow
Traditional associate or paralegal time to read, extract key terms, and flag deviations from a playbook is materially higher per document than the AI-metered path; the exact figure depends on the firm and the matter.
200–500
Contracts in a typical M&A data room
NDAs, MSAs, employment agreements, real estate leases, vendor SaaS contracts, amendments. A mid-market deal can mean $30K–$250K in diligence review costs.
$0
Cost visibility per document in existing AI tools
Current legal AI platforms (Harvey, Spellbook, Ironclad) charge per seat or per month. There is no per-document, per-model-tier, per-clause cost breakdown. The billing is as opaque as the AI.
0
Per-matter settlement rails that work at sub-cent scale
If you want to charge a client for AI-assisted diligence at actual cost, you need a settlement rail that handles $0.003 per document. Stripe cannot. Ethereum cannot. Tempo can.
02The Workflow

Six steps. One matter. Full audit trail.

01
Project intake
Upload a "data room" of 5–10 sample contracts: NDAs, MSAs, employment agreements, a real estate side letter, a vendor SaaS contract, amendments. Each gets a SHA-256 hash on ingestion.
02
Per-document classification and routing
Gemini Flash classifies each document: type, jurisdiction, redline complexity score (1 to 10). The P402 router uses the complexity score to route: simple NDAs get Flash, MSAs get Pro, ambiguous documents escalate. The routing decision is the visible thing in this demo.
03
Multi-document agentic review
Gemini Flash handles simple contracts (NDA clause extraction, standard deviation flags). Gemini Pro handles complex ones (MSA negotiation history, employment agreement non-competes, cross-document conflict detection). Each review event writes a ledger entry with the model tier used and the cost.
04
Cost-per-matter readout
Running USDC.e cost broken down by document, by model tier. The Stripe comparison is reframed for legal: "what would this matter cost if every clause review were a separate Stripe charge?" ($0.30 × 400 clause extractions = $120 in Stripe fees alone.)
05
Specialist escalation (future capability)
A future capability will route complexity-exceeding contracts to a specialist agent operating under an MPP escrow envelope; that path is not implemented on this page. In the current demo, escalation surfaces the contract for counsel review without delegating it.
06
Matter close and approval gate
The supervising lawyer reviews the AI assessment and approves or rejects the diligence summary. P402 records the decision. The final ledger supports an ABA-aligned audit posture: every AI action, every cost, every model tier, timestamped and onchain. The ledger does not replace counsel supervision.
03What This Demo Emphasizes

Routing is the headline. Cost transparency is the buyer value.

·Routing decisions are the visible thing

This is the demo where you see the router actually picking different models for different documents and saving money. Each document card shows: type, complexity score, model assigned, cost, and why.

·Budget caps per matter

A senior partner sets a $50 cap for a tier-3 contract review. The cap is enforced. If projected cost exceeds the cap, the analysis is blocked before the model is invoked. The decision is logged.

·Cost transparency is the buyer-visible value

Law firms billing clients per matter need defensible per-matter unit economics. This demo produces exactly that: a cost receipt for AI-assisted diligence that can be passed through to the client.

·ABA ethics audit trail

ABA Formal Opinion 512 (2024) prescribes that lawyers using AI understand and supervise its work. The P402 ledger provides supporting documentation: what model, what input, what output, at what cost, with human review recorded. The ledger does not satisfy supervision; the lawyer does.

04Unit Economics

Per-document AI cost is materially below the legacy workflow.

Legacy
Manual diligence per matter
Associate or paralegal time across 8 contracts for a mid-market deal data room. Operating cost in this path is materially higher per matter than the AI-metered path.
<$0.10
AI-metered diligence per matter
Gemini Flash for simple contracts + Pro for complex ones + Tempo settlement. Every cent tracked per document.
Per-model billing
Flash vs Pro cost breakdown
Simple NDA: ~$0.003 (Flash). Complex MSA: ~$0.018 (Pro). The model tier is visible in the ledger.
05Sample Matter
