Postprism

What it does

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.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
