Selfhosted

I use wallabag.it for this. I don't actually self host it, I've been a paying subscriber to the maintainer's hosted service for a few years now and I've had no complaints. It hasn't had many new features lately, but it does do what I want it to.

It doesn't capture comments in fediverse threads (see here: https://app.wallabag.it/share/6813d1f1616096.02317152 ), and there are some websites where it doesn't detect the contents of the article, but it does work the vast majority of the time.

I'm not sure what you could do about a Nextcloud integration. You can export articles as epubs and pdfs; I've done that a few times and put the exported files on my Nextcloud server. But there are also a bunch of wallabag apps for your different devices, which is what I use to read articles on those devices.

edit: Oh, I forgot to add that you can generate an RSS feed of your unread articles. So that could be added to Nextcloud's RSS reader.

Not selfhosted - tried a lots of solutions there but each of them fell short at one point. But I’m paying for Readwise Reader for a while and it’s the swiss knife for anything you listed up there. Plus, you can enable (optional) AI summaries, including for videos.

I never had time or patience for video essays that can give once sentence idea in a minimum 8 minute video (minimum for monetization), so I just throw them at Reader, have them summarized and I’m off to go in 30 seconds.

I use Zotero for this. Used to use it as purely a reference manager for scientific papers, but started storing all kinds of stuff for archiving or later reading. My workflow is getting all news/articles I might want to read from RSS, and add to Zotero what I want to keep.

With the browser plugin you can store snapshots as well, so you can preserve it if it changes or is taken down. Not sure how a mobile experience would be as I only filter RSS-items on my phone, but no reading.

You can use file sync through a paid subscription or use youe own WebDAV server for it (I will be moving to this). Other than that, it is a database and folder with files, so you can probably use SyncThing or store it directly in Nextcloud also I would think.

I am a folder-person, but it also supports tags so you have flexibility in how you organize.

i only found this 2 days ago but i seems like what youre after. its like a more modern version of wallabag

I use Readeck for 'read it later' type articles, things of interest. The downside of Readeck is that there is no one-click-easy way to back up your database if you want to move it to another server. You can, however go to /volume1/docker/readeck/ and download all the db files there manually which will allow you to move to another server. Make sure to grab the config.toml in the same directory. It has a Firefox extension as with most of these apps in it's genre. Probably has a chrome extension but I avoid chrome.

I use Karakeep (Hoarder) for stuff I've looked up to try to solve issues, such as pages from Grok where I have inquired about certain problems I may have been having.

Prediction: you'll never actually read most of what ends up on this to-read list.

I clicked on this post to bookmark it and read it later

I believe that I need these answers more than anyone else xD

Have you considered karakeep (formerly hoarder)? It does all of this really well - drop it a URL and it saves a copy. Has lists & tagging (can be done by AI if you want), IOS & android apps as well as browser extensions that make saving stuff super easy.

Karakeep might work for you

I use org-mode, which is kind of a structured text format, like Markdown but far fancier, in emacs. Can have to-do lists, deadlines, tables, display a weekly/monthly agenda with planned items, etc. I sometimes use it as a sort of mini-spreadsheet, as it can act something like a spreadsheet, with recalculating tables. I don't go in for the "whole life organizing in a tool" thing, so there's a lot of functionality that I don't use, but it's generally a superset of what I want, so it works well. There are various other software packages that support it.

I figured out (while using obsidian) that my brain works better when I dont have to worry about where to put things, but just tag them with topics, by relevance, e.g. So tags and the option to filter them would be nice!

Org-mode supports tagging, though I don't use them.

That being said, while other software packages do have varying degrees of support, and vim has some support it's really an emacs thing at its core, so I think that it's most interesting if you use emacs.

Make a textfile you sync between your devices. Save the URL, book name, or whatever; each on a new line.

So tags and the option to filter them would be nice!

You can tag them at will. Put "#TagName" next to an entry and later you can ctrl-f "#TagName" (or anything else) in the file. Notepad++, grep, and other tools will even give you a list of everything that matched your search criteria if you want to see all items that match at once.

I like to keep things simple!

I use Linkwarden. It’s similar to Raindrop, as mentioned by the other comment, but self hosted. It even creates archived copies of saved pages, similar to archive.org. My Links is a community made iOS client for it, and there’s an android client as well which I don’t know the name of.

Another popular option is Karakeep. It seems to have slightly more features, and it’s been a hit since I’ve tried it, but Linkwarden had the edge on UI/UX imo. Try both and see what you like.

I've actually been curious about something similar, and unfortunately I don't have an exact answer.

I'm currently self hosting ArchiveBox which saves a copy of the web page, but I find the UI to be pretty bloated. As an alternative, I've been curious about LinkWarden, but I have yet to set it up.

I know those two options aren't ideal as they don't directly integrate with NextCloud AFAIK, but they might support your other use cases?

raindrop.io works well for me for most of what you've mentioned, but its not selfhosted so I’m interested to find out other options also.
