Final Verdict

AISDR is a strong choice for outbound-led pipeline generation. It helps SDR teams automate prospecting and follow-ups through AI-generated outreach and sequencing. However, it relies on outbound engagement to initiate conversations. If your strategy depends on cold outreach and outbound prospecting, AISDR can support SDR productivity. If your goal is to convert inbound website visitors into qualified pipeline using real-time conversations, Knock AI offers intent detection, qualification, routing, and automated scheduling inside messaging-first workflows.
