How does the AI Reply Agent work?
The AI Reply Agent reads every inbound prospect reply, understands intent, and sends a relevant response automatically, usually in under 5 minutes. It handles the back-and-forth on interested leads, answers their questions, books meetings, and logs each reply and status change to your CRM. It runs continuously, so replies go out even outside business hours without anyone on your team touching the inbox.
How fast does the AI Reply Agent respond, and does it work 24/7?
The AI Reply Agent responds to interested prospects in under 5 minutes and runs 24/7, so a reply that lands overnight or on a weekend still gets an immediate answer. Speed to lead matters most in the moment a prospect replies, when the window opens and closes fast. Because the agent fires back instantly, you stay first to respond and never leave a warm lead sitting in an inbox.
Can the AI Reply Agent book meetings automatically?
Yes. When a lead is interested, the AI Reply Agent shares your Calendly link, handles the scheduling back-and-forth, and gets the call on the calendar automatically, with no involvement from your team. It also qualifies replies before booking, so meetings are set with genuinely interested prospects rather than every responder.
Will the replies match my brand voice and tone?
Yes. You configure tone, response length, and product-specific guidance once, and the AI Reply Agent applies it to every reply. This keeps responses reading like your best rep rather than a generic bot or a canned template, so reply management scales without losing tone quality.
Can I review replies before they send, or does it send automatically?
You choose. Run the AI Reply Agent on Human-in-the-Loop and approve each reply before it sends, or switch to Autopilot and let the agent handle everything, flagging only when it needs a second opinion. Either way you stay in control, and you can track every reply in the Activity Feed and review messages inside Unibox.
Can the AI Reply Agent handle objections and questions?
Yes. The AI Reply Agent is built to handle price questions, competitor comparisons, and "not now" responses, so warm leads stay warm and hesitant prospects get re-engaged. It answers questions in the reply thread using your product-specific guidance, keeping conversations moving toward a booked meeting instead of stalling when an objection comes up.
Does the AI Reply Agent integrate with my CRM and Slack?
Yes. Every reply, status change, and booked meeting flows back into your CRM automatically the moment it happens, so there is no manual logging. You also get real-time Slack notifications when something happens, an Activity Feed of every reply, and full message visibility inside Unibox, so nothing slips through.
Is the AI Reply Agent free to try?
