Looking for a app/service to save webpages

Problem: I scroll on lemmy, I talk to friends, I see some interesting page, project, funny meme or something else. (when I was on reddit i pressed SAVE, when I was on Instagram I pressed PIN (or something) and now I’m stuck with (uncategorised) information all over the place.

My current idea is: push everything to Telegram group where my bot listens, take the URL, maybe even extract some data and save it somewhere. 90% of my input will be over the phone but here and there also PC.

Any suggestions for self-hosted service to dump data in our (even better) to even skip whole bot part altogether?

UPDATE: Maybe I was a bit unclear. I want to "save" URLs and also somehow tag/categorize them. So I think plain bookmarks won't cut it, also flow is important (on mobile), switching copy/paste is to much hassle.
