Looking for a tree-structured hierarchical text editor / note-taker.

Requirements:

  1. Freeware
  2. Not ancientware (must have been updated during the last 3 years)
  3. Support italics/bold text
  4. Windows 7 SP1 compatible
  5. Can successfully import Treepad Lite files

Cherrytree seems to be an obvious contender, but the memory footprint of it in Windows seems extremely large.

You may try:

  • KeyNote [code] (it supports tree style editing),
  • Evernote (notebooks and tags which can be tree organised),
  • TreeSheets (it's table based),
  • The Guide (file format is human readable like XML),
  • wikidPad (wiki-like editor),
  • Zim (notes are saved as text files in folder hierarchies),
  • Treepad Lite,
  • 2do (Notes management),
  • Things (task management for Mac & iOS),

  • Thank you. I'll take a look. Note that Treepad Lite is not an option because it does not support bold or italic text and is certainly ancientware, with no updates in over 5 years. – RockPaperLizard Mar 19 '15 at 21:12

Treeline

Treeline is a very nice cross-platform (Win 7, 8; Linux) hierarchical notes manager. It is similar to Treepad (as the author himself notes).

As for OP's requirements:

  1. Yes Freeware
  2. Yes Not ancientware (must have been updated during the last 3 years)
  3. Yes Support italics/bold text | and more besides
  4. Yes Windows 7 SP1 compatible
  5. Note Can successfully import Treepad Lite files | Not sure - Treeline can import "plain text, tab-indented text and tab-delimited table files" as well as "generic XML files" (and import/export its own HTML); Treepad Lite can export (according to the online documentation) HTML and a "Treepad Lite file". There might be something compatible in there, but I'm not sure.

It ticks enough boxes to be worth investigation, at any rate. I use it from time to time under Ubuntu and enjoy having it in the "toolkit".

  • Nice bullet points. Is that kind of a SR standard? – Thomas Weller Nov 19 '15 at 15:15

    @Thomas I'm sure it's not an SR standard! You can see the meta-Q&A where this was concocted with some helpful guidance notes on usage in the comments. I find it very easy to use and a quick visual guide to the requirements list. – Dɑvïd Nov 19 '15 at 15:17

I like Workflowy It's web based, works on mobile and offline too. You can share bullets.

Meets most requirements:

  1. Freemium. Free gets 500 new bullets/month, no password protected sharing, no auto-backup to Dropbox.
  2. Stable, under active development
  3. Supports italics/bold text
  4. Web based, so supports all OSes with modern browsers
  5. You might be able to simply paste your old data to import it.

Try this web app https://webnote.in

Online notepad on the web for all devices with flexible tree-like structure.

Currently not supported:

  • italics/bold text
  • import Treepad Lite files
