ACS Citation Generator
ACS references, built as you type. No sign-up, no paywall, and the format is applied exactly — not guessed by a model.
ACS reference
Paste a reference, or start typing. It builds as you go — there is nothing to submit.
About ACS style
ACS is the reference style of the American Chemical Society, used across chemistry.
How ACS references work
ACS is a numbered style: references are listed in the order they are first cited, and the in-text marker is that number — usually a superscript.
Applied, not generated
The format is applied by a fixed set of rules, so the same input always produces the same reference — no model decides where a comma goes.
If your department's brief differs from what you see, follow the brief. A style guide is whatever your marker says it is.
Frequently asked questions
- What is ACS citation style?
- The reference style of the American Chemical Society, used across chemistry journals and coursework. References are numbered in the order they are first cited, and the in-text marker is that number rather than an author and date.
- Does ACS use superscript numbers?
- In published ACS journals, yes. Manuscripts submitted to ACS journals use a number in parentheses instead, and some departments ask for author–date. Check your brief — this tool gives you the number in parentheses, which converts to either.
- Why is the year bold in ACS references?
- It is part of the style for journal articles: the journal abbreviation is italic, the year bold, and the volume italic. That combination is the quickest way to tell an ACS reference from any other numbered style.
- Should I abbreviate the journal name?
- ACS uses CASSI journal abbreviations — “J. Am. Chem. Soc.” rather than the full title. Type the abbreviation into the journal field if your brief asks for it; this tool reproduces exactly what you enter.
Citations are the easy part
Referencing is mechanical. The draft around it is not — ReverseGPT writes with cited sources, checks the claims and edits the prose, in one place.
