xAI is testing out a standalone iOS app for its chatbot, Grok, which was available only to X users until now. The app, currently live in multiple countries, can access real-time data from the web and X and offers generative AI features like rewriting text, summarizing long paragraphs, a little bit of Q&A, and can generate images from text prompts, too. The company says its chatbot’s image generator model excels at 'photorealistic rendering.'
