Chat & Ask AI , one of the most popular AI apps on the Google Play and Apple App stores that claims more than 50 million users, left hundreds of millions of those users’ private messages with the app’s chatbot exposed, according to an independent security researcher and emails viewed by 404 Media. The exposed chats showed users asked the app “How do I painlessly kill myself,” to write suicide notes, “how to make meth,” and how to hack various apps. The exposed data was discovered by an independent security researcher who goes by Harry. Harry said that he had access to 300 million messages from more than 25 million users in the exposed database, and that he extracted and analyzed a sample of 60,000 users and a million messages. Chat & Ask AI is a “wrapper” that plugs into various large language models from bigger companies users can choose from, Including OpenAI’s ChatGPT, Anthropic's Claude, and Google’s Gemini.
