Automated reply bot for messaging apps like WhatsApp
Send automated replies to contacts on WhatsApp, Facebook Messenger, and other messaging apps. Perfect for migration notifications or vacation responses while respecting your privacy.

Atomatic is an Android application designed to send automated replies to everyone who contacts you on popular messaging platforms including WhatsApp, Facebook Messenger, Signal, and Telegram. Whether you're migrating to a privacy-focused alternative or simply need a vacation responder, Atomatic handles the communication for you.
Built for users seeking to reduce their reliance on mainstream messaging apps, Atomatic respects your privacy with zero analytics, no tracking, and complete transparency as a free, open-source tool. The app works by leveraging Android's notification quick-reply feature to automatically respond with your custom message to individual contacts and group chats alike.
Many users struggle to leave WhatsApp or Facebook Messenger because their social circles remain active there. Atomatic bridges this gap by automatically informing contacts of your new preferred platform—set a message like "I've moved to Signal, please reach me there" and let the app notify everyone seamlessly. No business account required, no new privacy policies to accept, just straightforward automation that puts you back in control of your digital communication.
When teams consider Atomatic, these hosted platforms usually appear on the same shortlist.
