Pros & Cons
ChatGPT

- Free tier is genuinely useful - not just a teaser for paid plans
- Custom GPTs let you build specialized assistants without any coding
- Best-in-class voice mode that feels like talking to a real person
- Massive third-party integration ecosystem and plugin marketplace
Cons
- Hallucinations are still common - it confidently makes up facts and citations
- Free tier rate limits hit hard during peak hours, quality drops noticeably
- Pro plan at $200/month is extremely expensive for individual users
- Custom GPTs quality varies wildly - most are just fancy prompt wrappers

ManyChat
Pros

- Visual flow builder is genuinely easy to learn, even for non-technical users

- Cross-channel flows connect Instagram, WhatsApp, SMS, and email in one sequence
- Shopify integration lets you sell products directly inside chat conversations
- Comment-to-DM triggers convert passive followers into active leads automatically
Cons
- Not built for customer support — lacks ticketing, routing, and agent handoff features
- Pro pricing scales with contact count, gets expensive fast above 25,000 contacts
- AI capabilities are basic compared to dedicated conversational AI platforms
- Heavily dependent on Meta platform rules — Instagram API changes can break flows
- No website live chat widget, so you need a separate tool for on-site support
