The Cost at 2,000 Messages/Month

Chatty's top plan ($199/mo) only includes 700 messages. At 2,000 messages, you're paying heavy overages:

Chatty (Plus Plan)

FunctionalAI (Pro Plan)

$99.99 — 2,000 msgs included

Even at lower volumes: FunctionalAI's Medium plan ($24.99) includes 400 messages — more than Chatty's $68.99 Pro plan (300 messages).

Where FunctionalAI Wins

8x Cheaper Overflow

$0.05 per extra message vs Chatty's $0.40. When you go over your plan, our overflow costs 8x less.

~3x More Messages Per Dollar

Our Pro plan ($99.99) includes 2,000 messages. Chatty's Plus ($199) includes just 700. You get more for less.

No Seat or Product Limits

Unlimited team members and products on every plan. Chatty restricts both by tier (1-unlimited seats, 100-20,000 products).

Knowledge Base with RAG

Upload documents, PDFs, and FAQs. Our AI uses Retrieval-Augmented Generation for accurate, context-aware answers from your content.

Smart Human Handoff

AI-scored escalation thresholds automatically detect when a human should step in. Not just basic transfer — intelligent routing.

Better Free Tier

75 messages per month, forever. Chatty's free plan gives you 50 messages total (lifetime, not monthly) — then you're done.

Where Chatty Wins (Honestly)

We believe in transparency. Here's where Chatty might be a better fit:

WhatsApp Built-In

Chatty has native WhatsApp integration today. We're still working on ours — it's coming soon but not live yet.

FAQ Page Builder

Chatty can generate SEO-optimized FAQ pages directly on your store. We focus on chat-based answers through the knowledge base instead.

Larger Community

4.9 stars with 1,700+ reviews on the Shopify App Store. They've been around since 2022 and have a proven track record.

Lower Entry Price

Chatty's Basic plan starts at $19.99/month (50 msgs). If you need very few AI conversations, their entry point is lower — though you get less.

The honest take: If WhatsApp is a must-have today and you need FAQ pages built into your store, Chatty covers those bases. But if you care about cost per message, message volume, and RAG-powered accuracy — FunctionalAI gives you significantly more value.

Who Should Use What?

Choose FunctionalAI if you...

  • Handle hundreds or thousands of messages per month
  • Want predictable costs without expensive overages
  • Need RAG-powered answers from your own documents

Choose Chatty if you...

  • Need WhatsApp integration right now
  • Want SEO-optimized FAQ pages built into your store
