This is one of those small, sharply-scoped browser extensions that solves a real workflow papercut for a very specific audience — and that's exactly why it caught my eye. zotero-scholar-checker is a Chrome extension that bridges your Zotero library with Google Scholar search results, surfacing your reading status and PDF tags directly on the Scholar results page.

What it does:

• Queries your local Zotero library while you browse Google Scholar
• Annotates each search result with whether you've already saved it
• Surfaces your existing PDF tags inline, so you can see at a glance how a paper fits into your prior reading
• Eliminates the constant alt-tabbing between Scholar and your reference manager

Why it's interesting: Most academic-workflow tools are either heavyweight cloud platforms or stale Firefox extensions abandoned circa 2018. A modern, focused Chrome extension that talks to a local Zotero instance is genuinely useful — and it's the kind of project that a researcher writes for themselves first and shares second. That tends to produce better software than tools designed by committee. The fact that it lives in the browser, rather than as another Zotero plugin, also means it intercepts the discovery step (Scholar) rather than waiting for you to remember to check Zotero after the fact.

Who would benefit:

• Graduate students and PhD researchers drowning in literature reviews where the same paper surfaces across multiple searches
• Academics doing systematic reviews who need to track which references have already been triaged
• Anyone using Zotero's tagging system seriously — the surfaced-tags feature rewards disciplined tagging habits

For a zero-star repo pushed today, this is the kind of niche utility that could quietly become indispensable to its small audience. Worth a star if you live in Scholar.
