Frequently asked questions

Do I need the WhatsApp Business API?+

No. You connect your own number by scanning a QR code; there's no template approval, message fee, or API application.

Which CRMs does it work with?+

It works with Zoho CRM, Bitrix24, HubSpot, and GoHighLevel. It sends and receives messages from cards, creates records automatically, and lets you manage your CRM from the chat.

What's different about Bitrix24?+

In Bitrix24 we connect to Open Channels as a bot; AI can also reply on every channel linked to the Open Channel, such as Instagram, Facebook Messenger, and web live chat.

How do I train the AI?+

By uploading text, a website address, FAQs, and files. The RAG-based agent answers from this information; it runs in automatic/semi-automatic/suggestion mode and hands off to a human when needed.

Yes. Without leaving the chat screen you can change the card's owner, move the Lead/Deal stage, and add a comment to the CRM card.
