Ibid is a privacy-focused citation manager designed as a browser extension for Chrome, Edge, Firefox, and Brave. It addresses the needs of users who require accurate citation formatting and value local data processing without server-side tracking or data collection. The tool supports over 2,600 official Citation Style Language (CSL) styles, including widely used formats such as APA, MLA, Chicago, Harvard, IEEE, Vancouver, and many others, with 74 styles bundled for offline use and the rest downloadable on demand.
The extension enables one-click citation generation by clicking the Ibid icon on any web page, with metadata automatically extracted from structured data. Users can also paste identifiers like DOI, ISBN, PMID, or arXiv ID, which Ibid resolves using sources such as CrossRef, Open Library, or NCBI to fill in missing citation fields. The tool offers a project-based library system, allowing the organization of citations by project with per-project styles, and supports sorting, filtering, starring, searching, and bulk operations. Import and export capabilities are extensive, with support for formats including BibTeX, RIS, CSL-JSON, EndNote XML, MEDLINE, and CSV. Exporting is available in nine formats, and users can filter exports by project and type. Experimental PDF support allows metadata extraction from PDF text, document properties, and DOI patterns, although results may vary depending on the PDF.
Ibid is powered by Hayagriva and Rust/WebAssembly, ensuring that all citation processing, library management, and import/export operations occur locally in the browser. The extension does not require an account, does not display ads, and imposes no paywalls or feature restrictions. All features are available immediately after installation, and the tool requests only minimal browser permissions. While most features work fully offline, DOI lookups require an internet connection. Ibid is offered as a free, open-source tool with no tracking, telemetry, or analytics, and no user data is ever sent to servers. The tool is suitable for anyone needing reliable, privacy-preserving citation management directly within their browser.
