Objectionary.AI is an AI-powered sales coaching platform created by Roman Slack that listens to live sales calls in real time and delivers instant, AI-generated responses to every objection a prospect raises. As an objection is detected during a call, the system surfaces a proven, on-script suggestion through an elegant teleprompter-style interface, complete with picture-in-picture support so reps can keep guidance visible while they talk.

The platform centers on customizable team playbooks, letting organizations build personalized response libraries tailored to specific products, industries, and scenarios and share them across their teams. Built-in analytics track which objection responses actually close deals, giving sales teams data-driven insight into how to refine their approach over time. Objectionary connects to existing phone systems and conferencing tools in under five minutes.

Privacy and security are central to the product. Objectionary runs locally rather than joining calls as a bot participant, protects data with AES-256-GCM and RSA-4096 end-to-end encryption, and holds SOC 2 Type II certification. User conversations are never used to train external AI models, making it suitable for teams handling sensitive customer interactions.
