Callbook AI is an AI collections agency for late-stage portfolios. The buyer decision is whether a lender, fintech, insurer, retailer, or BNPL provider wants multichannel agents that locate, contact, segment, and negotiate with borrowers while preserving a human and compliance control layer.

## What it does

Callbook says its agents work across voice, SMS, and email, keep one conversation history, classify ability and willingness to pay, and choose the next action—payment plan, human route, account review, or follow-up. Its developer API can trigger calls, receive webhooks, and retrieve call analytics ([Callbook homepage](https://www.callbook.ai/); [Callbook developer API](https://www.callbook.ai/developers.html)).
