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
PQC Imza is a web-based electronic-signature service that applies ML-DSA-44 (NIST FIPS 204) post-quantum signatures to documents. Senders upload PDFs or prepare documents using templates and an AI-assisted builder, then invite signers and decide which completed signatures to accept. Signers use the PQC Wallet mobile app to verify identity with the NFC chip in an ID card or passport and sign on their phones. The resulting PDF lists signers on each page and includes a QR code for later verification; the document fingerprint and signature records are anchored on SciChain. Customers can buy per-document credits, non-expiring credit packs, or monthly and annual plans; invited signers sign at no charge. The service is designed for individuals and organizations collecting electronic signatures. In Türkiye, these signatures are not qualified secure electronic signatures under Law No. 5070.
