markru is a Markdown library app for re-reading what you wrote — your notes and your half-read drafts, kept so you can come back to them.

Organize notes like books on a shelf, pick up reading where you left off, and keep the context of everything you've started writing.

■ Features

• Markdown editor with headings, lists, and checklists
• Organize notes as books, pages, and bound books
• Sort onto shelves (philosophy, practical, journal, work, and more)
• Continue reading: save and restore your place in a bound book
• Apple Intelligence for tag extraction, summaries, and Markdown formatting (iOS 26+)
• Quick capture, widgets, share extension, iCloud sync

■ For you if

• You write notes and never read them again
• You want to read your Markdown like a book
• You'd rather shelve your notes than lose them in a list

■ About the Ru series

markru is part of the Ru series — personal context infrastructure for building a record you can later hand to AI. It shares its thinking with taskru (restarting work) and liferu (recapturing your days).
