The short answer
Text-to-image creates a still from a written prompt. Grok Imagine is the broader generation experience around image and video workflows. Aurora is the image-model name that appears in public reporting and third-party explanations of xAI imagery, but the label and entry point can differ by product surface and release channel.
For a creator, the practical sequence is more important than the trademark history: make a frame you like, keep the source and prompt, then animate that frame. A strong still removes composition and identity decisions from the video render, which usually makes the motion result easier to control.
Where the handoff happens: This site is built for video generation and guides, not official still-image generation. Use your image surface for the still, then bring it here as a starting frame for image-to-video.
