# How I built an AI WhatsApp Auto-Responder with 0% Ban Risk using Google Gemini > Source: > Published: 2026-10-03 16:58:06+00:00 Most WhatsApp bots rely on Python web scrapers that get your phone number banned, or closed-source Play Store apps charging $10/month. I wanted an auto-responder that is completely free, private, and ban-proof. Instead of scraping WhatsApp Web, the app uses Android's native `NotificationListenerService` and `RemoteInput`—the exact system API used by Wear OS smartwatches and Android Auto. To WhatsApp's servers, the replies look 100% native. The project is 100% open-source under the MIT license: Feedback and PRs are welcome!
