Ulysses III vs TiddlyWiki

A few themes are baked in and a big selection of user-contributed styles to choose from are available on the Ulysses Style Exchange.

Ulysses has a clean, unobtrusive, easy to overview interface that allows focusing on writing. By default it's split up in 3 panes with sidebar, sheet pane and content pane from left to right. Unnecessary panes can be hidden.

Markdown formatting can be applied from the right-click menu, with keyboard shortcuts or from an optional markup bar. Necessary elemants to links, images, and footnotes are added by filling in a popover.

Pasted rich text and imported Word documents keep their formatting when converted to Markdown.

Attachments such as images, text notes, keywords and writing goals can be added to content. And to organize them keywords can be added.

Ulysses saves everything in the app so there's no file management outside of the editor involved. It organizes content in groups (folders) and sheets (files), has a powerful, easy to use search and allows adding keywords to attachments to help them be organized and found quickly.

Groups can have an unlimited amount of subgroups and the title of subgroup shows up in the pane view. Sheets can be split up, merged, glued together and easily moved around in the sheet pane by dragging and dropping. Great for splitting up larger documents into manageable chunks while still keeping an overview of the whole project and having the ability to move sections around quickly.

Contents of a group can be filtered by text, keywords or change date within headings, code blocks, images or any other marked up text. Filters can contain a combination of conditions and be saved to make a new group. Saved filters can be moved around to different groups and will return filtered results for that group. Selecting multiple groups will show the combined sheets of those groups.

You can operate Ulysses via keyboard only. No need for mouse.

The editor can export to Plain Text, RTF, Word, HTML, ePub and PDF with customizable styles for each option. It can also preview HTML directly in the browser.

There's no live-preview pane or an external previewer necessary. Ulysses displays styling inline.

Ulysses has options for highlighting current line, showing line numbers and enabling typewriter mode. Typewriter mode defines a place on the screen where the cursor should be so eyes are kept focusing in one place on the screen.

Content can be synchronised across devices via Apple's iCloud.

Ulysses comes with an excellently written documentation that covers everything there is to know about the software, including an extensive list of keyboard shortcuts as well as short and sweet introduction to Markdown and its benefits.

Ulysses is available for both macOS and iOS. This, combined with the cloud syncing allows users to work on their projects using any Apple device they have at the time.

The editor tracks statistics that shows how many characters, words, sentences, paragraphs, and pages a document contains and estimated reading time for slow, average, and fast readers. The statistics display in a popover that can be torn-off so it's constantly visible.

Goals such as how many characters, words, sentences, paragraphs, lines or pages should be written can be set to help get motivated.

Groups, tagging, and notes for each document.

Staff is helpful in answering questions on how to use the app.

A time (10hrs) and usage limited demo for Ulysses III is available.

The list of possible usages is practically infinite in TW, and more importantly it lets the user define their own method of dealing with their content.

Everything is stored in your device. You can back them up, encrypt and process however you want to. Works completely offline. Read your notes anytime, anywhere, in any platform, and sync between without cost.

Every card can link to other card, and other card will see the way it's linked to. Use Tag for nesting and build folder structure. Tags are tree shaped, and count of tag is limitless. Backlink can be automatically generated or selectively generated using advanced filter.

Renames titles in "Tags" and "List" fields by default. Relink plugin updates titles in all links automatically.

You can use the TiddlyWiki saver to save your TiddlyWiki file directly to your github repository. If you also use GitHub pages, then you can load your file wherever you happen to be, make changes, and update.

The official support forum is at talk.tiddlywiki.org. It's frequented by a large number of knowledgeable TiddlyWiki enthusiasts. You rarely see a question go unanswered more than 2 or 3 days, and in most cases questions are answered within minutes. For harder questions, the developer himself frequently wades in to add information.

You can create lists of anything inside TiddlyWiki like tags, title structure, date, custom fields and present it as links, checkboxes, tables or whatever structure you need using a few lines of wikitext (a markdown-like language with powerful widget ability built-in).

The official CodeMirror plugins allow you to close brackets, close tags, auto-complete, use VIM, Sublime or Emacs keybindings, and edit CSS, HTML, XML or Javascript text.

In cross-platform desktop APP TidGi and Android App Tiddloid you can create as much wiki workspace as you want, they are free forever.

In TiddlyWiki tags aren't some kludgey text-based add-on -- they're built into the design from the first. Tags can contain spaces and non-Latin characters. Tags are available at the top of each note. Click on a tag and you instantly see all the other notes that share that tag. You can then change the order of that list simply by dragging and dropping from the tag-pill. Tags can tag other tags, allowing you to create multiple types of TOC's with the built-in tag macros. You can create new notes tagged with the current note with just one click.

You don't have to worry about leaving your TW somewhere it might get exposed. You can activate the built-in encryption ability, using the Stanford Javascript Encryption Library to have your wiki encrypted with 256 bit security.

TiddlyWiki gives you the choice of whether you access additional resources (images, docx, pdfs) externally from the operating system or internally as embedded objects.
