CanUSign Reviews & Product Details

CanUSign is an e-signature tool where the recipient can check for themselves that a document is genuine and unchanged. You upload a PDF, place the signature fields and send a link; signers do not need an account. The finished PDF carries an RFC 3161 timestamp from DigiCert and an audit certificate, and a public verification page compares any copy with the stored version. Legally it is a simple electronic signature under eIDAS. Pricing is per document, no subscription required. Processing runs in Frankfurt. Operated by Devin Lemcke Capital UG (haftungsbeschränkt), Hamburg, Germany. REST API with webhooks and an MCP server for developers.
