Citegeist
Citation intelligence for Zotero, powered by OpenAlex.
Citegeist is a free Zotero 7+ plugin (tested through Zotero 9) that embeds citation intelligence directly into your reference manager. It pulls from OpenAlex, the free open index of roughly 250 million scholarly works.
For any paper Citegeist can identify, it adds:
- Citation count, field-weighted citation impact (FWCI), and percentile as sortable columns, so you can rank a folder by field-normalized impact rather than raw counts.
- Journal-level metrics (two-year mean citedness, h-index) and membership flags for the UTD24, FT50, ABDC 2025, and AJG 2024 lists, across 3,177 journals.
- Year-over-year citation trend, so a still-cited paper reads differently from a dormant one.
- A citation-network browser for forward (citing works) and backward (reference) snowballing. Results carry Open Access, Retracted, In Library, and No DOI badges, with one-click “Add to Zotero” on any of them.
- Automatic retraction flags from OpenAlex.
Nine columns in total, all off by default: right-click any column header to turn on the ones you want.
No account or subscription, and it works with DOIs, PubMed IDs, arXiv IDs, and ISBNs. OpenAlex has metered its API since July 2026, so anonymous use runs on a free daily allowance. That covers ordinary browsing; a library-wide scan can exhaust it, and a free OpenAlex API key lifts the ceiling.
