WhatsApp bot that replies to user messages using Gemini

Finally, an assistant that instantly answers on WhatsApp just like you would—no more endless typing or missed replies. Instantly. Humanly. Effortlessly.

  • Instantly when receiving a text message (whatsapp_cloud_api → webhook_message)
  • Send Prompt (gemini → send_prompt)
  • Send a text message (whatsapp_cloud_api → post_message)

Manually replying to every WhatsApp message from customers is exhausting, especially as your inbox grows with questions and requests around the clock. Missed or delayed responses can cost you business, hurt customer satisfaction, and leave prospects feeling ignored—while you and your team waste hours just trying to keep up. Every unaddressed message means lost revenue and damaged trust in your brand.

This Botize formula instantly connects your WhatsApp Business account to a customized Gemini AI assistant, so every time a user sends a new text, AI reads it and crafts a personalized response in seconds. The reply is automatically sent back to the user, 24/7, following your instructions and tone—no manual intervention needed. You can tailor the assistant’s behavior, set filters, and define how it answers, giving you flexibility while eliminating the repetitive strain of manual follow-ups. The transformation? Fast, consistent, always-on support that scales as you grow, freeing you from repetitive messaging and ensuring no inquiry slips through the cracks.
