Diigo is my 'comfy' link, image, and pdf collector. It serves the same function as Hypothes.is--annotator and aggregator. It has many more functions than Hypothes.is including outlining, screenshots, autoblogging.

Zotero is my go-to academic info database. It gathers meta-tags so that it can automatically create citations, bibliographies, and reports. Unlike its competitor Mendeley, it is open source and free. It works as a standalone and as an extension.
