Twitter/X is reportedly working on a new feature powered by its AI system, Grok, to enhance user posts. The 'post enhancer' feature will assist users in composing posts by offering options such as proofreading, fact-checking, shortening, rewriting content, and even rewriting in specific personalities. Additionally, Grok will allow users to rewrite captions, analyze posts before publishing, and suggest questions with background information for deeper engagement. The feature is currently being tested on the web version of the platform. This marks one of the most notable updates in social media functionality, as it integrates advanced AI capabilities to improve user engagement and content quality.
