Frequently asked questions

Does ChatBrain reply automatically, or do I still need to check WhatsApp myself?

ChatBrain answers customers automatically using your knowledge base. If it's not confident, or a customer asks for a person, the conversation is handed to your team instead of guessing.

Can the AI make up answers if it doesn't know something?

No. ChatBrain only answers from the information you provide. If something isn't in your knowledge base, it tells the customer it doesn't have that information yet and offers to connect them with your team.

Do I need my own Gemini API key?

Yes — you connect your own paid Gemini API key in AI Agent settings, so your usage and costs stay under your control.

Is there a free plan or trial?

ChatBrain is a paid-only platform. There's no free plan and no free trial — every subscription starts on a paid plan from day one.

Which WhatsApp do I connect — a personal number or WhatsApp Business?

ChatBrain connects through Meta's official WhatsApp Business Platform (Cloud API). You'll need a WhatsApp Business Account, which Meta requires for any business automation.
