DoCube: PDF Reader & Notes

As a teacher, I juggle hundreds of PDFs. DoCube's cross-document search is a lifesaver—it finds that one quote across all my papers instantly. The ability to link ideas between documents with annotations is like building a personal, interactive web of knowledge. Essential for anyone in higher education.

It wasn't until I started using DoCube that I unlocked a whole new way to read: just like a browser, it lets me open multiple tabs to read several books at once without any hassle. To me, it's long since been more than just a tool—it feels like a personal knowledge base that organizes all my scattered information in one place.

I can now directly jump to the referenced PDF locations from my Obsidian notes. Although DoCube has built-in Markdown support, migrating from Obsidian is too slow—I can only keep copying and pasting. I’m looking forward to batch import or other migration solutions being introduced.
