According to Microsoft Copilot (@Copilot), the Copilot AI chatbot will no longer be available on WhatsApp starting January 15th, 2026, due to WhatsApp's updated policies regarding large language model (LLM) chatbots on their platform (source: @Copilot, Nov 24, 2025). Users can continue accessing Copilot via the dedicated Copilot app on mobile, Windows, or through the web at copilot.com. This move highlights the increasing regulatory scrutiny on AI chatbot integration within major messaging platforms, prompting AI providers to invest in proprietary channels. For AI businesses, this shift underscores both the risks of platform dependency and the opportunity to develop direct user engagement through owned platforms.
