This started as a Q&A tool, but the most-requested thing from researchers was something else entirely: notes trapped in the one paper they're on. Past a few hundred sources, an idea you highlighted is effectively lost unless you remember which PDF it's in. So I built the fix.
Cross-paper annotation browser
Every highlight in your library in one window not one PDF at a time.
Filter by colour, tag, keyword, and type, combined live.
Export the filtered set with citations copy as Markdown/HTML or save as a standalone Zotero note, each source cited once in your Zotero citation style with its highlights beneath.
Click any annotation to jump to that exact spot in the PDF.
Grounded Q&A lets you ask questions across your entire Zotero library. Instead of re-reading dozens of papers, query all of them at once — and every claim in the answer links back to the exact passage it came from. Click a citation and jump straight to that page in the PDF. No invented references, no hallucinated sources. Free, open source, and it runs against your own library. Built for researchers who need answers they can actually trust and cite.
