QOwnNotes

QOwnNotes is the open source notepad with
Markdown support
and todo list manager for GNU/Linux, macOS and Windows,
that works together with Nextcloud Notes
and ownCloud Notes.

You are able to write down your thoughts with QOwnNotes and
edit or search for them later from your mobile device, like with
Nextcloud Notes for Android
or the Nextcloud / ownCloud web-service.

The notes are stored as plain text markdown files and are
synced with Nextcloud's/ownCloud's file sync functionality.
Of course other software, like Syncthing or
Dropbox can be used too.

If you like the concept of having notes accessible in plain text files, like it
is done in the Nextcloud / ownCloud notes apps to gain a maximum of freedom
then QOwnNotes is for you.

Visit the project page here: QOwnNotes project page

To manage your todo lists in the web and on your mobile devices, you need to
install the Tasks backend on Nextcloud
or ownCloud.

To get more on-line features for your notes, like versioning and trash access,
you might also want to install the QOwnNotesAPI
app on your server.

To access your ownCloud notes from your mobile device you may want to get one of these:

For Android and OwnCloud: MyOwnNotes
For Android and Nextcloud: Notes
For iOS: CloudNotes

On Android you could also use any sync-tool like Synchronize Ultimate or FolderSync
to sync your note files and use software like neutriNotes or
Markor to edit your notes.

On iOS Notebooks
may also work well (syncing notes via WebDAV).

Installation

Please visit Installation for all the ways to install QOwnNotes.

Building QOwnNotes

To get the most current features you can build the application from the source
code. Download the latest source here:
QOwnNotes Source on GitHub as ZIP

Alternatively you can also check out the code directly from the git repository:

shell
git clone https://github.com/pbek/QOwnNotes.git -b release --depth=1
cd QOwnNotes
git submodule update --init

Then download Qt Creator, you will also
need the packages qtwebsockets to build QOwnNotes with Qt6
(only qtwebsockets for Qt5). If you build under Windows, you want to stick to
MinGw 64-bit.

Afterward open the project file src/QOwnNotes.pro and click on
Build / Build Project QOwnNotes.

Or you can build it directly in your terminal:

shell
cd src

# build binary translation files if you want another language than English
lrelease QOwnNotes.pro

# prepare build process and build the application
qmake
make -j4

Building QOwnNotes For Development

If you are going to work with the code, then you can do the following instead of the above:

shell
cd src
qmake CONFIG+=DEV_MODE CONFIG+=debug ..
make -j4

The DEV_MODE variable enabled higher warning levels + precompiled headers.

Please feel free to contribute source code to this project, make suggestions or
