Cherrytree: One of Best Note Taking Software For Ubuntu

Cherrytree is a hierarchical note taking application, featuring rich text and syntax highlighting, storing data in a single xml or sqlite file.

Cherrytree is good note taking app for building your personal knowledge base and also fantastic for learning code. It gives a simple way to manage in a tree structure hundreds of notes. It can easily handle images, lists, tables, hyperlinks and syntax highlighting (when the rich text is disabled in the current node).

With cherrytree, you can print & export notes to PDF, and even import from other notes, such as basket, tomboy, gnote, keepnote, and so on.

Here’s a list of features:

  • rich text (foreground color, background color, bold, italic, underline, strikethrough, small, h1, h2, h3, subscript, superscript, monospace)
  • syntax highlighting (only when the rich text is disabled in the current node)
  • images handling: insertion in the text, edit (resize/rotate), save as png file
  • lists handling (bulleted, numbered, to-do and switch between them, multiline with shift+enter)
  • simple tables handling (cells with plain text), cut/copy/paste row, import/export as csv file
  • codeboxes handling: boxes of automatically highlighted text into normal rich text
  • alignment of text, images, tables and codeboxes (left/center/right)
  • hyperlinks (links to webpages, links to nodes/nodes + anchors, links to files, links to folders)
  • intra application copy/paste: supported single images, single codeboxes, single tables and a compound selection of rich text, images, codeboxes and tables
  • cross application copy/paste (tested with openoffice and gmail): supported single images, single codeboxes, single tables and a compound selection of rich text, images, codeboxes and tables
  • copying a list of files from the file manager and pasting in cherrytree will create a list of links to files, images are recognized and inserted in the text
  • print & save as pdf file of a selection / node / node and subnodes / the whole tree
  • export to html of a selection / node / node and subnodes / the whole tree
  • export to plain text of a selection / node / node and subnodes / the whole tree
  • toc generation for a node / node and subnodes / the whole tree, based on headers h1, h2 and h3
  • find a node, find in current node, find in all nodes
  • replace in node names, replace in current node, replace in all nodes
  • iteration of the latest find, iteration of the latest replace, iteration of the latest applied text formatting
  • import from basket, cherrytree, gnote, keepnote, knowit, mempad, notecase, tomboy, treepad lite, tuxcards, zim
  • export to cherrytree file of a selection / node / node and subnodes / the whole tree
  • password protection (using http://www.7-zip.org/)
  • tree nodes drag and drop
