Elon Musk’s xAI could soon make its next move to compete with OpenAI: launching a standalone app for its Grok chatbot.

Musk created xAI as an alternative to OpenAI, the company he helped found but later distanced himself from over ideological differences. Now, The Wall Street Journal reports, xAI is planning to launch an app as soon as December that could go head-to-head with OpenAI’s ChatGPT as it races to scale up.

Currently, users can access Grok through X, but only if they subscribe to the service. Citing unnamed sources, the Journal reports that xAI is also behind customer support features for Starlink, part of Musk’s other company, SpaceX. X did not immediately respond to a request for comment on the report.

OpenAI’s ChatGPT, Google’s Gemini, and Anthropic’s Claude already have their own apps and free products, making Grok an outlier among other chatbots.
