Everything citation tools should be

One-click citing

Click the Ibid icon on any page. Metadata auto-fills from structured data. Copy the formatted citation instantly.

Smart auto-enhance

Paste a DOI, ISBN, PMID, or arXiv ID. Ibid resolves it via CrossRef, Open Library, or NCBI and fills missing fields automatically.

Actually accurate

Powered by Hayagriva — the same CSL engine that powers Typst. Supports all 2,600+ official Citation Style Language styles with correct et al., title case, and locale terms.

Zero data collection

No telemetry. No analytics. No bandwidth hijacking. All processing happens locally in your browser via Rust/WebAssembly.

Import & export anything

Import from BibTeX, RIS, CSL-JSON, EndNote XML, MEDLINE, CSV. Export to 9 formats. Drag & drop files or paste text. Filter exports by project and type.

Project-based library

Organize citations into projects with per-project styles. Sort, filter, star, search, bulk operations. Side panel stays open while you research.

PDF support is experimental. Ibid extracts metadata from PDF text, document properties, and DOI patterns — but PDFs vary widely in how they store metadata. Some extract perfectly, others may give partial results. You can always paste a DOI manually for reliable metadata.

2,600+ citation styles

74 styles bundled offline. 2,600+ more downloadable on demand from the official CSL repository. Once downloaded, they work offline too.
