Grok

Ask Grok questions in a chat and receive explanations, written responses, research help, or striking generated images. The AI assistant from SpaceXAI covers mathematics, science, coding, general research, writing, analysis, and multi-step problem-solving.

Grok can examine documents, photos, and links shared in a conversation, then use web and X access to find current information, news, trends, and public discussions. Voice mode accepts spoken questions and returns spoken replies, while context or conversations from other AI tools can be transferred into Grok. Grok Imagine creates images and short videos from text, including videos with sound and clips built from photos. Users can also generate images by voice and edit existing pictures by removing objects, replacing backgrounds, or applying artistic styles.

It suits students, researchers, writers, developers, and anyone who wants an assistant for investigation, creation, or everyday questions on Android. The app is freeware, with a paid version offering additional features. It may share photos and videos, app activity, and two other data types with third parties, and it may collect location, personal information, and five other data types. Data is encrypted while being transmitted, and users can request that their data be deleted.

Free to use — a paid version with additional features is also available.
