Not quite the correct application but linkwarden would work. Stores all your links but also backs everything up via html, plain text, and pdf. You can categorize content and tag content. Then there are filter and search tools.

You can just give it PDFs and it will import them over as well. Only saves them as a pdf but still would work.

I’m guessing this is not the best approach but wanted to give you options.

FountainPens just one of my smaller less popular hobbies. That and EDC. We do have at least an EDC channel here but it’s now near as big.

I tried to log back in to Warframe recently aftet not playing for 3 or so years. There is so much new stuff. Idk what to even do. Game feels daunting now.

Some of the smaller subs I used to frequent don’t see as much traffic as I would like. Like cycling and edc. I just have to be the change I want to see. I will I swear, just need to fine some spare time.
