Meta AI vs Agent Sonic: Which WhatsApp AI Should You Use?
Quick answer: Meta AI is built into WhatsApp for free and is great at answering questions and generating text. Agent Sonic is a personal assistant that takes action — it sets reminders, reads your documents, manages your calendar, and follows up with people for you. If you want a chatbot that talks, use Meta AI. If you want something that gets your admin done, use Agent Sonic.

The short answer
Meta AI and Agent Sonic both live in WhatsApp, but they're built for different jobs.
Meta AI is an answer engine. Ask it a question, get a reply — facts, ideas, a draft, an image. It's free, it's already there, and for quick Q&A it's genuinely useful.
Agent Sonic is a doer. It remembers your context and takes action across your day: reminders that fire on time, documents read, calendar managed, people followed up with. The question isn't which is 'smarter' — it's whether you want answers or outcomes.

Where Meta AI wins
Credit where it's due. Meta AI is free and already inside every WhatsApp account, so there's zero setup.
For fast, throwaway questions — 'explain this term', 'draft a birthday message', 'make me an image' — it's quick and good enough. If that's all you need, you don't need anything else.
Its reach is unmatched too; for casual users who'll never set up a tool, being built-in is a real advantage.
Where Agent Sonic wins
The gap shows the moment you want something done rather than answered.
Meta AI can tell you it's a good idea to call the accountant Monday. Agent Sonic will actually message you Monday at 9 to do it — and every Monday after that if you ask.
It reads the PDF you forward and pulls the total. It checks your calendar and adds the meeting. It messages a client to chase a document and reports their answer back. And it remembers all of it between conversations, so you're never repeating yourself.
Which one should you pick?
Pick Meta AI if you want a free, built-in chatbot for occasional questions and don't want to set anything up.
Pick Agent Sonic if WhatsApp is where you run your day and you'd rather delegate the admin — reminders, documents, calendar, follow-ups — than do it by hand.
They're not mutually exclusive, but most people who try Sonic do so because answers stopped being enough; they wanted the work actually done. Agent Sonic is in early access — request access at tryagentsonic.com.
