OKDOC AI is an e-signature platform that tracks what happens after you send. It shows opens, reading time per page, scroll depth and a tap heatmap, flags deals as hot, viewed, abandoned or stalled, and sends a WhatsApp alert while the client is reading. Closer, its follow-up agent, ranks deals and drafts follow-ups for your approval. Sign & Pay collects payment on signature, and every document is sealed with a certificate and SHA-256 fingerprint. It works from ChatGPT or Claude through an MCP connector.
