Krypin is a minimalist writing app where your content lives entirely in the URL hash. No accounts. No databases. No servers storing your data. Write a note, and the URL becomes the save file. Share the link, and anyone can read it. It's that simple. Features: • Endless mode for long-form writing • Stack mode for bite-sized cards (~3 tweets each) • Auto-generated memorable stack names ("Crimson-owl") • Dark mode + ambient soundscapes (river, metro, brown noise) • Export your library anytime
