Clarisign is an AI deal workspace where autonomous legal agents run transactions from intake to close. They draft contracts, redline changes and track conditions under counsel's review.
About Clarisign
What Is Clarisign
Clarisign is an AI deal workspace built for legal teams that run transactions. Instead of acting like a chatbot that answers questions, it hands defined tasks to autonomous agents that carry a deal through diligence, drafting, negotiation and closing. Each agent works inside a checklist you approve, so the human stays in charge of the substance.
The product targets the drudgery that slows deals down. A data room review, a term that means one thing in the purchase agreement and another in the disclosure letter, a string of consents and conditions: each one eats hours that counsel could spend on judgment calls. Clarisign takes those steps and shows its work with source links and side-by-side diffs. It runs inside your own cloud tenant, never trains models on your files, and offers data residency, legal holds and audit-grade logs.
The catch is scope and price. Clarisign is aimed at legal practices and deal teams, not casual users, and there's no public free tier in the sense a consumer app would have. You start with a pilot around a single live matter. Teams with one-off, low-stakes paperwork will likely find it heavier than the job needs.
Getting Started
- Book a 15-minute call through the official site to scope your first transaction.
- Run one live matter end to end as a Deal Pilot through the Word add-in, Table View and Chat.
- Feed in your letter of intent or term sheet and let the agents generate a draft checklist.
- Ingest the data room, review the first drafts and diffs, then approve or negotiate each change.
- Track conditions, consents and signatures through to the closing binder, and export to Word or Excel anytime.

Key features
Deal Intake and Smart Checklists
Clarisign turns your letter of intent, term sheet and brief into a living checklist. It maps the entities, dependencies and gating conditions involved, then updates the list automatically as facts change. That means the deal's structure stays visible instead of living in someone's head.
Data Room Ingestion and Bulk Diligence
The agents ingest a virtual data room and run due diligence across the whole set at once. You get flagged clauses, figures and risks rather than a stack of files to read. It's the part of deal work that eats the most hours.
First Drafts from the Term Sheet
Feed in a term sheet and Clarisign produces a first draft of the agreement and its ancillary documents. The output is a starting point to refine, and you can export to Word or Excel whenever you want to take over editing.
Negotiation Copilot and Redlining
Every suggestion the AI makes shows where it came from, a side-by-side diff against the current text, and how the change ripples through related documents. You accept or negotiate each point, so control stays with counsel.
Cross-Document Consistency Engine
The system reconciles terms across a letter of intent, the main agreement and the disclosure letter. It catches the internal contradictions that creep in when one document is updated and another isn't, which is where late-stage surprises usually come from.
Conditions, Consents and Approvals
Clarisign tracks conditions precedent, consents and approvals and coordinates signatures through to the closing binder. Registration with the platform happens through a short call rather than a self-serve signup.
Pros and cons
Pros
- End-to-end coverage means one workspace handles intake, diligence, drafting, negotiation and closing instead of four disconnected tools.
- The human-in-the-loop design shows sources and cross-document impact, so reviewers can verify a change in seconds.
- Security is strong for legal buyers: deployment inside your own cloud tenant, no model training on your data, and SOC 2 plus ISO/IEC 27001 controls.
- Word and Excel export keeps the work usable in the tools legal teams already have.
Cons
- There's no advertised free plan or public price list, so you have to talk to sales before you know the cost, and smaller practices may find that barrier to entry steep.
- It's built for transactions and deal teams, so if you mostly handle routine, single-document paperwork, a lighter contract tool will fit better.
- Agent-driven drafting still needs a qualified lawyer to review the output, so it reduces effort rather than replacing legal judgment.
Frequently asked questions
It runs legal transactions from start to finish with autonomous agents. They read a data room, draft the agreement, redline changes, reconcile terms across documents, and track conditions and signatures, all under a checklist your team controls.
