Verified contract review — now shipping

Contract review with verified findings.

5 independent AI reviewers. Consensus required. Your keys, your machine, nothing leaves.

729+ documented AI hallucination cases in legal practice

$30,000 largest sanction for unverified AI output (Sixth Circuit, March 2026)

Privilege risk After US v. Heppner, cloud AI contract review may waive attorney-client privilege

How It Works

Three steps. Five reviewers. One verified report.

Drop in a contract. Redline runs five independent reviewers that must reach consensus before any finding makes the report.

Drop in a contract

NDA, MSA, SaaS agreement, DPA, SOW — any deal document your team handles daily.

5 reviewers inspect independently

Liability, compliance, completeness, financial terms, and deep review — each reviewer works in isolation.

Consensus-verified report

Only findings that survive semantic quorum appear in the final report, each with evidence anchors.

Why Redline

The difference between guessing and knowing.

Single-pass AI tools give you plausible output. Redline gives you verified findings with evidence.

Single-pass AI

✗ One model, one pass
✗ Hope for the best
✗ No evidence trail
✗ Cloud-hosted, privilege risk

Redline verified review

✓ 5 agents, 2 passes each
✓ Semantic quorum required
✓ Evidence-anchored findings
✓ Local-first, privilege preserved

Verified Finding Quorum: 5/5 reviewers

Uncapped Indemnification Obligation

Section 8.2 imposes unlimited indemnification on the receiving party for "any and all claims arising from use of the Services" without a liability cap or carve-out for consequential damages.

Evidence Anchor § 8.2, lines 142–158 — Master Services Agreement v3.1

Privacy Architecture

Your API keys. Your machine. Zero data retention.

Redline is a BYOK workbench. You bring your own OpenAI or Anthropic keys. Documents stay on your hardware. After US v. Heppner, this matters.

No cloud upload

Documents are parsed and reviewed entirely on your machine. Nothing is transmitted.

No training on your data

Your API keys go directly to the provider. Redline never sees, stores, or trains on your documents.

Privilege preserved

Local execution means no third-party access to work product. Attorney-client privilege stays intact.

Pricing

Redline — $399/month.

Stripe Checkout handles signup. Stripe Customer Portal handles seat management, payment methods, and cancellations without putting billing in the local review loop.

Single Plan

$399/month

Up to 5 seats included. Cancel anytime.

One verified-review subscription for legal teams that want shared access without adding billing friction to the local BYOK workflow.

Desktop app, CLI, and TUI included
Legal-contracts pack included
First verified email is added automatically, then seats fill as teammates verify
Provider spend stays on your own OpenAI or Anthropic account

You pay Redline for orchestration and verification. You keep paying your AI provider directly for model usage.

Need to swap who can use the license? Manage billing in the Customer Portal, and Redline will enforce the seat limit the next time a teammate verifies.
