[@citekey]
), supporting page numbers & multiple citations ([@citekey, p. 23; @citekey, p. 42]
). Can also be configured to use LaTeX, Multi-Markdown, eta templates, Org Mode,[[wikilinks]]
,#tags
orbare citkeys
as citation format. - App-independent: Works system-wide, in every text field of every app.
- Smart Search: Search for citekeys, authors, title, publication, keywords (tags), include or exclude authors in et al., tab-completion, fuzzy-matching, sorting recently used entries to the top.
- Feature-rich: Paste single-entry bibliographies, open URLs, open or create literature notes, attach PDFs, search for
.csl
files online, and more. - Blazingly Fast: Considerably quicker than any other citation picker (~200 ms to fully reload a library with ~4000 entries).
- Simple Installation: Just enter the path to your
.bib
file, and you are ready to go. - Lightweight Reference Manager: Automatically rename and file PDFs, remove, entries, and more.
- Quickly Add New Entries: Select a DOI or ISBN and add them directly to your BibTeX library via hotkey.

- About the Developer
- Download the latest release.
- Enter the BibTeX Library path.
- Use the citation picker via the Alfred keyword
ct
, or set a hotkey for the citation picker by double-clicking the respective field in the workflow window.
Note As soon as the workflow is admitted into the Alfred Gallery, it is automatically updated via the Gallery. Until then, you have to update the workflow manually by downloading the latest release here at GitHub.
Use the ct
keyword press the hotkey in any text field to start the citation picker.
- You can search for the title, author/editor (last name), year, collection, or journal name.
- Prepend
@
to a word to search for a citekey, for example@Grieser2020
. - Prepend
#
to search for keywords (tags), for example#sociology
. - Smart Queries: You can search for any combination of the above. For example, the query
2020 #cognition grieser
searches for entries published in 2020, with the tag "cognition," and with "Grieser" as author/editor.
Note
The citation picker prioritizes entries first by how well they match, then by the recency their use, and lastly by how recently they have been added to the library.
↵
: Paste the citekey of the selected citation.⌥ + ↵
: Add another citation.⌘⇧ + ↵
: Paste an inline-citation (citation without surrounding formatting, for example@Grieser2022
instead of[@Grieser2022]
)⌘ + ↵
: Add page numbers before pasting the selected citekey.- Confirm the page number with
⌥ + ↵
to add another citation afterward. - Confirm with
⌘⇧ + ↵
for an inline-citation with page number (@Grieser2022 [p. 42]
).
- Confirm the page number with
⌃ + ↵
: Open the URL in the browser.⌘ + C
: Copy the URL to the clipboard.- In both cases, if the entry has a DOI but not a URL, the citation picker uses the DOI-URL (
https://doi.org/…
) instead.

You can use the scp
and select Change Citation Format to change the format of the citations:
- Pandoc (default)

- eta template

Note
Not all formats support all citation-related features. For example, adding Page numbers as well as inline-citations are not supported for Latex, Wikilinks, and Tags, and iA Writer does not support multiple citations.
If you want to use a format that is not available, you can customize the format yourself by changing the workflow environment variables starting with _format
. (Tutorial: How to set environment variables in Alfred)
If there is a citation syntax that is commonly used, or if you want to improve support for an existing format, feel free to open a Feature Request.
You can also make a PR to this file which defines the citation formats.

universal action
orhotkey
: Uses the selected DOI, ISBN, or URL containing a DOI to add a new entry to the library.- Experimental: A second universal action can be used to parse & add a bibliographic entry. Requires anystyle.
- The new entry is added to your library, with a correctly formatted and unique citekey. Afterward, the entry is opened.
file action
: Use theAdd Entry and Auto-file
action on a PDF file that includes a DOI. The DOI is automatically retrieved from the PDF, the entry added to the library, and the PDF auto-filed (see PDF Management Actions). Requires pdfgrep.
Note Adding or removing entries does not work with the BetterBibTeX Zotero Plugin since the plugin only does a one-way-sync (Zotero ➞ BibTeX file), meaning any changes to the
.bib
file are not reflected in Zotero.
- The citation picker looks in the folder specified in the workflow settings for files that are exactly named like the citekey, optionally followed by an underscore and some text like
{citekey}_{title}.md
. The citekey must not contain underscores (_

The following features require that all your PDFs are located in the folder specified in your workflow settings.

- Citation Style Search: Search for a citation style (

). - Force Buffer Reload: Force a reload of the citation picker. Mostly for debugging purposes.
As this is probably the most feature-rich and most performant citation picker on macOS, it is kind of a bummer that not many people know about this. However, I do not really know where to "advertise" this, since I am not aware of any forum or website for academics that work with markdown and BibTeX. So if you know a good place, feel free to contact me or spread the word yourself. 😊
In my day job, I am a sociologist studying the social mechanisms underlying the digital economy. For my PhD project, I investigate the governance of the app economy and how software ecosystems manage the tension between innovation and compatibility.

QLmarkdown and Peek both enable previewing of Markdown documents. Peek works with a wide range of other file types than Markdown, but costs around 5€.
QLMarkdown
is free, but only works for Markdown and requires some minor setup. To enable the proper display of YAML headers, you need to enable the respective setting in the Advanced Options ofQLMarkdown
or Peek. ↩ -
