I am on a search for the next best PDF annotation app for my needs. I’m posting an opening for others I know on this forum who have comparable interests.
It must work on the iPadOS platform. I find this platform to be far more efficient for annotation and markup than working on macOS.
It must allow highlighting and image-selection/capture as a minimum.
It must allow the user to add notes to the annotations.
It absolutely must allow the user to export the annotations as a markdown file, including images. This is my make-or-break criterion (I am heading toward using Obsidian for the review process).
It should allow the user to add tags to the annotations.
It should work dynamically to share with other i(Pad)OS and macOS apps such as Devonthink or Bookends.
It should be “light-weight” (meaning that it should just do annotating well and export its results, not also contain the mapping/studying features as in LiquidText or MarginNote).
I have two current contenders, Highlights and Zenreader.
→ Zenreader, the new kid on the block, meets my absolute requirement but does not currently have an iPad app. As a new kid, it is also rather clunky in its implementation. It appears to be an electron app (which does not bother me).
→ Highlights has an iPadOS app but does not meet the absolute requirement directly. A round-about way to meet the absolute requirement is to export the markdown to Devonthink and then export/link that content to Obsidian. Highlights has its own annoyances, but I can overlook them if it only exported the annotation set directly to markdown.
As an aside, I will test MarginNote (since I have it) if only to discover whether annotations can be exported as markdown. In my initial tests over a year ago, I found the annotation features in MarginNote to be exactly what I’ve wanted. I have however been seriously put off by being locked in to its storage format. I see in the meantime that a plug-in exists to support markdown export. Let’s see where this goes.
