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.

Document Upload for Training

Upload PDFs and arbitrary documents into RAG-powered stores. Chatty trains on products, FAQs, and custom Q&A — but doesn't accept uploaded documents per its public docs.

No Per-Seat Pricing

We don't charge per seat (single-owner workspace model). Chatty's plans cap team seats and product counts by tier.

Public API on Day One

Build integrations and automations from the free tier. Chatty doesn't advertise a public API on its Shopify listing.

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.
