Clarisign

Clarisign positions itself as an AI deal workspace for legal teams running complex, document-heavy transactions. Agents take a term sheet or letter of intent and turn it into a living checklist, ingest a virtual data room (VDR), produce first drafts of the main agreement and ancillary documents, and keep cross-references consistent across the whole pack — for example between an LOI, an SPA and a disclosure letter. Conditions precedent, consents and approvals are tracked as the matter progresses, and the platform can coordinate signatures and assemble a closing binder, exporting to Word or Excel at any point.

The design philosophy is human-in-the-loop: AI works under counsel's control. Each suggestion surfaces its source, a side-by-side diff, and the downstream impact on related documents, so reviewers can accept or negotiate rather than retype. Core feature areas include deal intake and smart checklists, VDR ingestion and bulk due diligence, first drafts from the term sheet, a negotiation copilot with redlining, a cross-document consistency engine, and CP/consent/approval management.

Clarisign emphasizes enterprise trust. It states that deployments run in the customer's own cloud account — your tenant, your keys, your network — and highlights ISO/IEC 27001 plus SOC 2 Type I and II controls for security, availability and confidentiality. It also states that customer content is never used to train foundation models, and offers data residency options, legal holds, deletion-on-request and audit-grade logs. Commercial terms are handled through engagement plans and a contact-sales motion rather than published self-serve tiers, so buyers should expect a scoped enterprise agreement.
