Caliu is a quiet place to write. Open it and start typing: no account, no setup, no clutter. Markdown takes shape as you type, everything works offline, and your notes stay on your device. When you want them everywhere, create a free account and they follow you across iPhone, iPad, Mac and the web. Sync is free, and it stays free. Writing comes first Headings, lists, tasks, quotes, code and links format as you write. There is no preview pane and no mode to switch: what you see is your note. The interface steps aside and leaves you with the page. Organised the way you think Tags instead of folders, because one idea can belong in many places. Nest them, colour them, and find any note in seconds. Link notes to each other and follow a thought from one to the next. Pin what matters now, and archive what you are done with without losing a word. There when you need it Native on iPhone, iPad and Mac, with a web app for everything else. Put a reminder on any note and Caliu nudges you on whichever device you pick up. Save things to Caliu straight from the share sheet, or add a thought from your Apple Watch. Yours, and only yours No ads. No tracking. Nothing you write is used to train AI. Your notes live on your device first and sync encrypted, and Caliu is built in the EU under GDPR. Export any note as Markdown or plain text whenever you like, share one as a public link when someone needs to read it, and delete your account at any time. Deleted means deleted.
