PostBox turns your MacBook's notch into a drag and drop area for sharing your work. Drag an export in, write the caption once, and post to X, Bluesky, Threads, LinkedIn, Dribbble, Instagram, Pinterest, Behance, and Cosmos all at the same time. No more copying and pasting to each platform individually.
