Postprism is the editor-first social media manager that ends copy-paste. Write your post once, and AI rewrites it natively for Facebook, Instagram, Twitter/X, Bluesky, Threads, LinkedIn, TikTok, YouTube, and Pinterest — matching each platform's tone, length, and hashtag rules. Schedule everything from one calendar. Built for solo marketers, freelancers, and small teams who'd rather create than reformat.
