Hundreds of thousands of user conversations with Elon Musk's artificial intelligence (AI) chatbot Grok have been exposed in search engine results - seemingly without users' knowledge.
Unique links are created when Grok users press a button to share a transcript of their conversation - but as well as sharing the chat with the intended recipient, the button also appears to have made the chats searchable online.
A Google search on Thursday revealed it had indexed nearly 300,000 Grok conversations.
It has led one expert to describe AI chatbots as a "privacy disaster in progress".
