Closign.io

Closign is an AI e-signature tool that drafts legally binding agreements from a plain-language description and routes them for signing. You describe the agreement you need, and Closign's AI drafting feature writes it, identifies the parties and signing order, and lays out the fields automatically. Signers then complete the document field-by-field on any device through guided e-signing, with no account required on their end. For common documents, ready-made templates cover NDAs, offer letters, and freelance contracts so you are not starting from scratch. Teams and workspaces add role-based access and shared document management, and every signed document gets an audit trail and certificate with SHA-256 sealing. On security, Closign uses email OTP verification, keeps encrypted storage in India, and states it does not train AI on user files. The target users are freelancers, startups, HR teams, legal and CA firms, and sales agencies who need an agreement drafted and executed quickly without a lawyer in the loop for routine paperwork. For BestAIFor readers comparing contract tools, Closign's distinction is that drafting and signing live in one flow rather than bolting an AI writer onto a separate signature product.
