Same text file. Finally a pleasure to open.
A simple, local, open-source editor for .txt and .md files.
A calm, block-style Markdown editor for the .md and .txt files already on your computer. Nothing gets imported, and every page stays an ordinary file.
Free and open source. No account needed.

Type the way you already type
Markdown shortcuts work as you go, and the marks disappear into formatting. The file underneath keeps them.
Press / for anything
Every block type sits in one menu. Type to filter it, then drag any block by its handle to move it.
Shortcuts you already know
Type the Markdown you'd type anyway, and the page formats itself.

Frontmatter as properties
YAML at the top of a file shows as tidy rows under the title.

Tables that grow
Hover for + bars that add rows and columns. Tab in the last cell adds another.
Set the page your way
Default, serif or mono type, small text, full width, and light, dark or system themes.
Change one line. One line changes.
Notaboek treats the file on disk as the source of truth. It rewrites only the block you touched, so your * bullets, __bold__ and hard-wrapped lines stay as you left them.
Opening never writes
A file is only saved after you change it, shortly after you stop typing.
A crash can't leave half a page
Saves go to a temporary file that gets swapped in, wherever Windows allows it.
Outside edits get caught
If another program changes the open file, a clean page reloads. With unsaved edits, Notaboek asks which version to keep.
File details stay put
Line endings, byte order marks, UTF-16 and Windows-1252 stay as they were, unless you add a character the encoding can't hold.
Unsaved text is never dropped
If a save fails, Notaboek won't switch pages, and closing the window asks first.
Deleting goes to the Recycle Bin
Uninstalling leaves your folder and your pages where they are.

Is Notaboek really free?
Yes. The app has every feature and costs nothing, and it is open source under the MIT licence.
Where are my notes kept?
In the folder you open, as ordinary .md and .txt files. Notaboek doesn't import them or copy them anywhere else.
Can I sync my notes between computers?
Yes. Your notes are ordinary files, so OneDrive, Dropbox or Git will carry them for free.
Do I need an account?
No. The desktop app has no sign-in at all.
Is there a Mac version?
Not at the moment. The desktop app is Windows only.
