What is it?

FractalNote is online editor of hierarchical notes (or note trees) for Nextcloud server.

You can view/edit CherryTree (*.ctb) files with it in browser.

Current development phase is pre-alpha. Just nodes of plain text are editable, others are read-only.

How to use FractalNote?

• Use CherryTree program for windows/linux desktop computers to create hierarchical notes.
• Save your hierarchical note tree as [filename].ctb with CherryTree program.
• Upload [filename].ctb to Nextcloud
• Edit uploaded file online: https://[your-cloud-server]/index.php/apps/fractalnote?f=[filename].ctb
• Install Nextcloud desktop synchronisation client.
• Put [filename].ctb under Nextcloud synchronisation folder of your desktop computer. From now the file will be uploaded into server automatically after every saving.
• In CherryTree program preferences keep checked autosave option and Edit->Preferences->Miscellaneous->Reload after external update to CT* file option. From now file changes made online will be downloaded automatically even while you navigating through the file with CherryTree program.
• [filename].ctb size should not be big (about <= 5MB), because for now the full file gets loaded with every page refresh in browser.
