About Yanna
Yanna is a document-automation API built specifically for Voice AI agencies using Retell.
It lets your AI agent send retainers, NDAs, leases, agreements, and any contract instantly right from the call.
Think of it like this:
You’re on the phone with a rep… they fill out your form in real time, pick the right document, and send it straight to your email or text.
That’s exactly what Yanna does for Retell agents.
How Retell Customers Use Yanna

Deliver the contract before the call ends, boosting signature rates
Track signatures via webhooks and update your CRM automatically
