A deeper review bench
Run risk review, clause drafting, proofreading, restructuring, redundancy checks, sensitive-data scans, and Word-ready exports from the same review surface.
Redaction, review, and judgment transfer in one macOS workflow.
Before Signing: AI redaction and contract review before signature.
Redact sensitive details with AI assistance and manual precision, review contracts from your position, evolve reusable review rules, and route work through the model provider you already control.
Start with a 3-day free trial. No credit card required.
A review system that evolves
Accepted edits, repeated decisions, and prior marked-up contracts can become a practical review style, so the next contract starts closer to how you actually work.
Brain to Brain transfer
Curate review rules and examples into a shareable playbook so one person's hard-won judgment can move into another reviewer's daily workflow.
AI-powered redaction command center
Before Signing treats redaction as a reviewable workflow rather than a black box: automatic detection, AI suggestions, manual selection, category controls, and export-ready decisions sit together.
Detect default entities such as parties, addresses, identifiers, bank details, and titles.
Add manual redactions for project names, deal terms, or any span the machine should not guess.
Use AI assistance where it improves boundaries, categories, and multilingual entity recognition.
Keep a clear review map so accepted, rejected, and custom redactions stay auditable.
From one-off AI output to a repeatable contract operating system.
Before Signing is designed for the commercial moment before signature: redact what should not be shared, review what may shift risk, preserve the work in real Word artifacts, and keep your AI runtime flexible as providers and languages change.
Diverse contract review
Review risks, draft clauses, proofread, restructure, deduplicate, scan sensitive data, and export Word comments or tracked changes.
Cold-start learning from prior edits
Import contracts you have already revised so Before Signing can learn your review habits faster. Because this learning step may call your selected model API, redact the samples first or use non-sensitive examples.
Brain to Brain mechanism
Export curated playbook snapshots and import them into another review profile so expertise moves between people.
Hot-swappable engines
Move between OpenAI, Claude, DeepSeek, Qwen, Ollama, or an enterprise gateway without rebuilding the workflow.
