I’m sorry to report that I’ve failed to revolutionise markdown :(
Nor have I managed to create a custom superset that extends markdown enough that you can make a video game with it. You can also not edit markdown with it (imagine that!).
It’s just a reader, and I did manage to make it pretty easy to read markdown in a browser, you can drop a file, paste raw markdown or paste a URL to parse the contents into markdown, among other ways to pass content into the app.
You can annotate if needed (select anything and start typing), download an annotated or clean copy, or export just the notes. The annotated copy is still a plain .md file, the notes live inside it as comments, drop it back in and everything comes back.
You can even share it with others, either as a view only or annotator link, no account, only people holding the link can open it, and you can delete it at any time.
I don’t want your money, your email, or your personal data, I just want you to be able to quickly read markdown in the least intrusive way possible.
The reader is very opinionated, give it a whirl at reader3000.com
If you like it, great, if you don’t, fair enough :D. I invested a lot into making it resilient, but if a normal markdown file breaks it (not one purposefully constructed to break things), lemme know.
