The Niman mark: an anthracite square with a cream N and one blue tile

Niman Is More (than) A Notebook.

A multiplatform Markdown note-taking app where your notes are just files. One note = one .md file on disk — no lock-in, no proprietary format.

What Niman does

What the app does today, in its own words from the README. What is planned is in the issue tracker.

Notes as files

One note = one .md file on disk, organized in folders however you like. The database is only a rebuildable index; your files are the source of truth.

One surface, three modes

The source editor, the live (WYSIWYG) editor and the read view are one widget of Niman's own; switching modes does not move the page.

Links that reach anywhere

Wikilinks and Markdown links between notes, into a page of a PDF or a chapter of a book, with a dialog to create a missing note.

Journal, tasks and reminders

One note per day with a calendar; a todo list over todo.txt; reminders with exact alarms on Android and tray timers on the desktop.

Export, your way

A note, a folder or the whole library out as Markdown, a self-contained HTML page, a print-ready PDF or an EPUB book.

Sync to your own server

Per-library WebDAV sync to Nextcloud, ownCloud, a NAS or any WebDAV folder, with an offline queue that retries by itself.

Make it yours

Day, night or system brightness, and a palette — System, Niman, Catppuccin, Solarized, Gruvbox — or a theme of your own, exported as JSON.

Pictures, PDFs and books

Pictures, PDFs and EPUB books open in the note pane on every platform, zoomed and paged where they need it, opening where you left off.

Android, Linux, Windows

Niman runs on Android (minSdk 35), Linux (Wayland) and Windows. macOS and iOS are not built yet, but the code is kept portable.

Status: the project is under active development; what is planned and what is in progress is tracked in the issue tracker.
