Datarate

Most bookmarking tools stop at saving a link. Datarate takes a rating-first approach: instead of just capturing a URL, you give any page, paragraph, or image a title, a star rating, and tags. That structure makes your saved material searchable and comparable later, and it works for the fragments you actually care about — a paragraph in an article or a chart in a report — not just whole pages.

The extension adds an AI layer on top. It organizes what you save and suggests relevant links, so a rating session can surface further reading you would otherwise miss. Collections can stay private for personal research, be shared with friends for lightweight collaboration, or be contributed to the wider community, which makes the tool useful both as a private notes shelf and as a small social knowledge space.

Datarate is published on the Chrome Web Store by developer ziv and has been actively maintained, with recent version updates. It is a lightweight, single-purpose browser tool rather than a full research suite, so it fits best when research, reading, or curation happens in the browser. Some features are offered as in-app purchases.
