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.

FAQ

Castor vs. ManyChat FAQ

Is Castor a replacement for ManyChat?+
For DM-driven D2C sellers, yes, that's the intended swap. ManyChat is a flow builder you configure yourself; Castor is an agent you set up by answering questions, and it answers from your real product information instead of following a fixed flow.
Does ManyChat understand a customer's actual question, or just keywords?+
ManyChat's free-flow paths are mostly keyword and button-triggered. It's good for simple, predictable flows, but a customer who phrases a sizing question differently than expected can fall outside the flow. Castor reads the actual message and answers from your product info regardless of phrasing.
Which is cheaper?+
ManyChat's paid plans scale with contacts and can get expensive at volume. Castor starts at $49/month flat for live, continuous replies across Instagram, Facebook, and WhatsApp, with a free tier to test on and a 5-day free trial on both the Starter and Growth plans.
Do I need to build anything myself with Castor?+
No. ManyChat requires you to build and maintain flow diagrams. Castor is set up by answering plain-language questions about your business, there's no flow builder, no nodes, and no automation logic to maintain.
