Frequently Asked Questions about Clarisign
Can Clarisign generate a first draft SPA directly from a term sheet?
Yes. Clarisign generates first drafts of share purchase agreements and ancillary documents from term sheets, which then move into its negotiation and redlining workflow. This cuts the manual drafting work for M&A transactions, though your team still reviews and approves every suggestion before it moves forward.
Does Clarisign track consistency across all deal documents automatically?
Clarisign includes a cross-document consistency engine that flags term conflicts between the SPA, ancillary documents, and other transaction files. It reconciles definitions and obligations across the full deal set, which matters because a misaligned term in one document can derail closing.
Can I run Clarisign in my own cloud account?
Yes. Clarisign deploys in your own cloud infrastructure with your keys and controls, rather than on a shared vendor platform. This arrangement is built for legal teams and firms that need data sovereignty and cannot route deal documents through external servers.
How does Clarisign show where its document suggestions come from?
Every AI suggestion includes source attribution and a transparent view of its cross-document impact. Your legal team can see exactly which clause, prior deal, or input triggered each redline or negotiation proposal, which keeps human counsel in control of the transaction workflow.
