AutoResponder.ai sends automatic replies across WhatsApp, Facebook Messenger, Instagram, Telegram, Signal, and Viber based on rules a user sets, without needing a server or a separate chatbot platform. Developer Tim Kosmala runs the app under TK Studio out of Coburg, Germany; the app first launched on Google Play in 2015 as one of the first WhatsApp auto-reply tools, with a full rebuild released in 2017.
Rather than a single canned message, a user builds unlimited custom rules that match incoming messages and trigger different automatic responses, and can wire those rules into ChatGPT, Gemini, or Dialogflow for AI-generated replies instead of static text, or trigger separate device actions through Tasker integration. The app runs entirely on-device on Android rather than routing messages through a third-party server.
Small business owners, freelancers, and anyone managing message volume across multiple messaging apps are the core users, given the multi-platform reach. Pricing runs a Free plan at $0/month with core auto-reply functionality and a Pro plan at $3.33/month unlocking the full feature set, backed by a seven-day free trial of Pro.
