关于这个工具

Writing a blog post or thread, but the cover image is "draft me an asset in Figma" away from being done? Generate one in 30 seconds. Pick aspect ratio (3:4 for RedNote, 9:16 for Stories, 16:9 for OG / blog hero), type your title and subtitle, choose a gradient — done. Renders fully in your browser. The exported PNG is high-resolution (2x) and ready to upload.
