PearSign
PearSign is a platform for drafting, sending, signing, and managing contracts electronically. Users can upload PDF or Word documents, add signature and other fields, send them to signers, monitor status, and receive a sealed PDF. For a new agreement, users can describe terms in plain language to generate an editable draft with clauses to review and change; PearSign says the feature is not legal advice. Guided mobile-first forms accept validated answers and file uploads, and signers can complete them through a link without an account. Completed documents receive an AATL-backed PKCS#7 seal via Sectigo and a certificate of completion. The audit record includes timestamps, signer details, IP address, device and authentication information, and a document SHA-256 hash. PearSign lists integrations including Google Drive, Dropbox, Salesforce, Twilio, and Postmark, plus a REST API and webhooks. Its documentation says test keys are disabled while an isolated sandbox is being built. Free includes 3 envelopes per month; paid plans start at $15 a month. After the monthly allowance is exhausted, new envelopes wait until reset or upgrade.
