Where FunctionalAI wins

Predictable Message Pricing

Our Pro tier is $99.99/mo with 1,500 messages included and $0.10/msg overflow — flat per-message pricing with no per-conversation metering.

No Product-Count Tiers

Your plan sets storage per knowledge store (5–150 MB), not how many products you may have. Chatty's plans tier product counts.

Handoff on Your Own Rules

Describe when a person should take over in plain sentences, each with a threshold. Every shopper message is scored against them before the AI replies, and a match pauses it.

Where Chatty wins, honestly

Where Chatty legitimately wins:

WhatsApp Today

Chatty supports WhatsApp Business as a channel. We currently do not.

FAQ Page Builder

Chatty generates a public FAQ page from your knowledge base. Useful for SEO + customer self-serve.

Built-in SEO FAQ Pages

Auto-published, indexed FAQ pages tied to your store. Good organic traffic value if SEO is your channel.

Established Shopify App

Older app with thousands of installs and reviews. If long Shopify-app track record matters, that's real.

The honest take: If WhatsApp-today and SEO FAQ pages matter to you, Chatty has them. If you want document-based RAG and predictable per-message overflow at $0.10 — that's us.
