So I built Kite, a Markdown reader for Mac. It has QuickLook just like Preview and I have baked in features that help people reading lot's of AI markdowns.
It one-time purchase, no subscription.
I put it on TestFlight so you can try it before paying anything. I would really like this crowd to try to break it. Tell me which files render wrong,what feels off, what is missing.
