Side by side
How they actually differ
ManyChat is built around visual flows: you drag together triggers, buttons, and branches to script how a conversation should go. It works well for predictable, button-driven interactions, but it doesn’t read and understand an open-ended message the way a person would, so a customer who types their question instead of tapping a button can fall outside the flow you built.
Castor takes a different approach. Instead of a flow you design, you answer a short set of plain-language questions about your business, products, pricing, and voice. Castor then reads every incoming message, understands what’s actually being asked, and answers from that real information, so it handles the long tail of phrasing a fixed flow can’t anticipate.
