If you spend a lot of time trying to remember papers, presentations, textbooks, blog posts, stack overflow answers, or twitter threads from 3 years go, then you may want **Zotero**.

It's a normal desktop application, there's a cloud tool I dont use, and a really useful Firefox extension. 

## It's basically bookmarking with some extra features:

* Automatically extract info like authors, title, metadata, and links.
* You can attach the snapshot or PDF automatically or manually. This prevents link rot, which is great.

There's some others too:
* You can add notes and then search through them later. It's occasionally useful.
* Tagging and "collections" make some sense.
* Importing from bibtex
* Duplicate detection

There's also a lot of features that make sense only for academics like automatic bibtex export or even other citation styles.

## Things it doesn't do right

* Can't add your own citation type (like web applet or something). So limited to just "websites" for some things.
* Doesn't store youtube videos
* Does not provide text search inside of PDFs
* It doesn't let you keep a stack/queue of interesting papers or such (i.e. it's not Pocket)
