X rolls out one-click Grok caption generation in its mobile apps
XFreeze · x · 2026-09-25
X now lets users generate image captions with one click right inside the post composer on both Android and iOS, powered by Grok.
User XFreeze admitted he had been generating captions separately in Grok Build and copying them over, unaware the feature was already built into the app. A small but easily missed update for everyday users.
