CLI grammer checker! Uses languatool on the backend - can be done over internet or you set up your own local server. This is everything I've ever wanted.

Well, actually better vim integration would be amazing, as an lsp or some other way of 'linting' errors instead of going through them one-by-one. But one day that will happen.

Markdown GUI editor built on pandoc underneath.
Live preview and so on.

Unfortunately built on electron, but might still be useful every now and again (or for other people).

Open-source collaborative spreadsheet editing application - seems fairly mature

I go over using NeoVim and LaTeX to take notes with, but I specifically talk about talking notes with Mathematics.

Prose diffs for any document format supported by Pandoc. Can be used to compare two different pandoc documents or, much more useful to me, to convert 'track changes' changes in an office (word, libreoffice, ..) document into criticmarkup diffs.

Set it up to read from a directory of markdown files and you will have a nicely designed, fully text-searchable personal knowledge base accessible over the web

Simple, efficient and pretty.
A minimal GUI Journaling application - it gets out of your way and allows you to write in markdown.

One neat feature is its calendar view which lists the quick titles of your journal entries for days passed and thus gives you an overview of what you did when and when you were journaling.

If you need a terminal equivalent use jrnl instead.

A very simple full-text search tool for plaintext files.
Can support multiple indexes, uses established search db library, is set up with a single config file.

A quick overview on how to handle async processes in luv in Neovim.

Uses example of spawning a pandoc process, which is a good example starting point for reviewing implementations.

Pandoc preprocessor/wrapper to consume, display, merge and diff criticmarkup (i.e. track changes mode).

Nice markdown notes management / writing app.

Simple interface, reminiscent of old Evernote clients - but targeted plainly toward plaintext note-taking.

A brief comparison of AsciiDoc and Markdown.

AsciiDoc does have some less visually translatable decisions, but also has a more concise and (above all) universal syntax.

Creating multiple bibliographies with pandoc -- using a lua filter and applying it to the material.

The filter, as it stands, may require use of multiple .bib libraries, but can probably be adapted to get its two bibliographic informations from the yaml header itself?

Using criticmarkup to generate word 'track changes' style reviews and merging 'track changes' style reviews into criticmarkup. Back and forth.

Marked as suspended development, but if it works it could prove very useful.

Cross-platform desktop note-taking app. Sticky notes with Markdown and Tabs. All in one .txt file.

Interesting application of txt files to be shown in 'corkboard' view.
Unfortunately packaged as electron app, making ~100kb of actual code into ~200mb of program.

The idea could be used however, for a re-arrangeable corkboard / network view of my personal notes.

A collection of portable pandoc templates with no dependencies - ryangrose

Useful as templates, but even more as inspiration for creating my own stand-alone templates.
By hosting on git{hub,lab}, we get access to the raw styling files and can pull them down in the process,
so that truly only the template itself is needed and is portably packed in e.g. ~/.pandoc/templates .

Can ultimately (perhaps) also be used to create inter-changeable gallery for generating quick previews from the editor.
