Markdown notes are easy to write โ and easy to forget. markru is built for what comes after writing: shelving, binding, and rereading your own notes like books. (Some features โ tag suggestions, summaries โ use Apple Intelligence on supported devices.) YOUR NOTES, SHELVED LIKE BOOKS Promote finished notes from drafts to your bookshelf. Browse by shelf, search, and sort by what you read last. BIND NOTES INTO ONE READABLE BOOK Combine related pages into one book. Reorder pages, add new ones, and read them as a single piece โ or unbind anytime. WRITE IN CLEAN MARKDOWN A focused editor with live preview and a formatting bar for headings, lists, checklists, tables, code, and more. Some writing helpers โ tag suggestions, formatting, and summaries โ are partly powered by Apple Intelligence, right on your device. Note: These AI-assisted features require a supported device and OS version. Where Apple Intelligence isn't available, they simply fall back to manual entry โ everything else in the app still works, and no note content is ever sent to an external server. CAPTURE IDEAS IN SECONDS Quick Capture works like a paper memo: jot it down, the title can come later. Import .md and .txt files, or send text from any app with the share sheet. KEEP YOUR SHELVES IN ORDER See your note, shelf, and book counts at a glance. Clean up, compress, or bind notes as your library grows. PICK UP RIGHT WHERE YOU LEFT OFF markru remembers your reading progress in every book, so returning to your notes feels like reopening one. PRIVATE BY DESIGN No account required. Your notes live as plain Markdown files on your device or in iCloud Documents โ never on our servers. Write lightly. Reread deeply.
