📸 PostStudio: AI Photo Editor, Collage Maker & Carousel Splitter

PostStudio is an offline photo editor and collage maker built for creators who post daily: crop and adjust photos, build multi-photo collages, split one image into a scroll-stopping Instagram carousel, and export all without an internet connection or a login.
