Citations and bibliography
Fill in the source details once and get the bibliography entry and the in-text citation in APA 7, MLA 9, Chicago 17 and IEEE, with a list that piles up and sorts itself.
Write every author as Surname, First name and start a new line for the next one. If you type only John Smith the tool takes the last word as the surname, so compound surnames really need the comma.
Your bibliography
Your data stays in your browser: the bibliography is kept in the local storage of your device and is never sent to a server.
How to use it
Pick the source type, fill in the fields that appear and the entry takes shape while you type, together with the citation you put in the text. When the entry looks right press «Add to bibliography» and it lands in the list below, which survives closing the page. Every entry can be reopened with «Edit», removed, copied on its own or copied together with all the others.
Why changing style also changes the order
APA 7, MLA 9 and Chicago want the final list in alphabetical order by the first author's surname, and by title when there is no author. IEEE works the other way round: it numbers sources in the order they appear in the text and cites them with that number in square brackets, so switching to IEEE stops the sorting and renumbers the list. This is the difference people miss most often when they change style halfway through a paper.
The author rules that trip everyone up
APA 7 lists up to 20 authors, and from the twenty-first it writes the first 19, an ellipsis and the last one. MLA 9 keeps only the first author followed by et al. from three authors on. Chicago lists up to ten authors in the bibliography and from eleven writes the first seven with et al., while the in-text citation uses et al. from three. IEEE lists up to six names and keeps only the first beyond that. The tool applies these thresholds on its own and says so under the preview.
What the tool does not do
It does not check whether your data is true, it does not look the source up online and it does not validate the DOI. It leaves the capitals of the title alone, because APA wants sentence case while MLA and Chicago want title case, and an automatic conversion would do more harm than good. The italics of titles are lost if you paste as plain text, so the copy button first tries to keep them and falls back to plain text only when the browser refuses. Finally, many departments ask for local variants: if your course guide says something different, the guide wins.
Nothing leaves your device
The tool runs entirely in your browser. The bibliography is saved in the local storage of your device, so you find it again when you come back, and it is never sent to a server. One warning though: if you clear the site data, switch browser or browse in private mode the list is gone, so copy it into your document once you are done.
