About

AirSign is a cloud-based electronic-signature and business-app platform for organizations that need to prepare, send, sign and manage documents online. Users can send documents for signature, collect signatures from signers on web-enabled devices, and retain completed signed PDFs with an audit trail. Optional apps cover training, customer management and invoicing, staff records, assets, compliance reminders, forms, projects, scheduling, timesheets, social publishing and a company wiki. The suite supports teams handling approvals, onboarding, records and administration. Its browser-based signing workflow requires no separate app for signers. AirSign also provides a REST API and an MCP server for AI-assisted preparation of document drafts for review. Integrations documented on product pages include Xero and Microsoft SharePoint. AirSign offers a limited free tier and paid monthly plans; the service is hosted in Australia.

About

ProofSign is an electronic-signature and document-verification platform for individuals, professionals, teams and organizations signing finished PDFs. Users upload documents, invite signers and approvers, and run single- or multi-party workflows. Participants verify email access with a one-time passcode. ProofSign records signing intent, participant actions and timestamps in an audit trail. Completed PDFs include a SHA-256 fingerprint and evidence recipients can check through a public verifier without an account. The service supports agreements and finalized documents that need an auditable signing record and a way to detect later file changes. Its free plan allows single-party signing and verification for up to 10 documents monthly under fair use. Users can earn credits through onboarding and signing milestones. The Pro plan includes a verification API.
