Side by side
How they actually differ
Chatfuel is built around a visual canvas: you connect blocks, buttons, and conditions to script how a conversation should unfold. It's approachable for simple, predictable journeys, but every path a customer might take has to be anticipated and built by hand, and a message that falls outside the script gets a generic fallback instead of a real answer.
Castor skips the canvas entirely. You answer a short set of plain-language questions about your business, products, pricing, and voice, and Castor 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.
