Frequently Asked Questions
Can a WhatsApp AI bot process voice notes and photos of invoices or IDs?
Yes. When a user sends a WhatsApp voice note or image, our webhook pipeline downloads the encrypted media, transcribes audio via Whisper/Deepgram or extracts fields via Gemini/Claude Vision, and responds in seconds.
