Caliu - Markdown Notes

Plain text editor, private

Free · In‑App Purchases

Caliu is a markdown notes app for people who write. No clutter. No toolbars in the way. Just a quiet canvas, your words, and a way to find them again later. Write in Markdown. Sync everywhere. Think clearly. It runs natively on iPhone, iPad, and Mac, and stays in sync with the web app. Everything works offline. Your notes live on your device first and travel only when there is a connection. • The writing page. Headings, lists, quotes, code blocks, and links format as you type. No preview pane, no switching modes. The interface steps aside so the writing can take over. • Tags, not folders. Ideas overlap, so one note can belong to many places. Nest your tags, colour them, search them. Organisation that matches the way you think. • Reminders that find you. Pin a time to any note and Caliu nudges you on whichever device you have picked up. Good for the things you would otherwise forget you wrote down. • Sync you never think about. Start on your Mac, finish on your phone. Your notes are already there. No sync button, no spinner, no waiting. • Just talk. Tap the mic and think out loud. Caliu transcribes, trims the filler words, and turns your voice into clean Markdown: real headings and lists, not a wall of text. • Long-term memory. Caliu keeps snapshots as you write. Scroll back through a note's history, preview any moment, and bring it back in a tap. • A mood, not a menu. Ten colour themes, light and dark, plus more than 30 fonts to make the page yours. Pick the one that matches the hour. • Export, share, own your work. Export any note as Markdown, plain text, HTML, ePub, PDF, RTF, or TextPack. Share a note as a public link when someone needs to read it. Nothing locks you in. • Notes that talk back. A full REST API and a built-in MCP server, so Claude, Cursor, or your own scripts can read and write notes on your terms. • Private by design. Your notes are nobody's business. No ads, no selling your data, no tracking you across the web, and nothing you write is used to train AI. Kept on your device first and synced encrypted, built in the EU under GDPR. Export everything or delete your account whenever you like. Deleted means deleted. Caliu Pro The heart of Caliu is free: writing, tags, sync, and offline everything. Caliu Pro adds voice dictation, version history, every theme and font, unlimited attachments, more export formats, and API access. Try it free before you decide. Made with care by a small, independent team of one. No setup. No clutter. Just your thoughts, kept warm.

- Faster and lighter. Typing stays smooth in long notes, notes open quicker, switching and selecting notes on Mac no longer stalls, and search and launch are faster too. Caliu also uses less memory while it works, and the bigger your library, the more you notice. - Local Files on Mac. Point Caliu at a folder and your notes live there as plain Markdown files, with images and attachments beside them. Edit them in Finder, Obsidian or any editor and the changes come straight back into Caliu. - Paste that keeps its shape. Copy from a web page, Google Docs or Notion and the headings, lists, links, tables and code blocks arrive as clean Markdown instead of one flat block of text. - Now in 13 languages. Korean and Traditional Chinese join the eleven Caliu already spoke. - Apple Watch fixes. Your notes now load on the watch, anything you capture there reaches your iPhone and Mac, and voice notes work from your wrist. - Fixes and polish. Batch export finishes, reminders keep arriving, and more small fixes on iPhone, iPad and Mac.
