Generate references in AMA style — the format of the AMA Manual of Style used by JAMA and most US medical journals — from a DOI, PubMed ID, PMCID, ISBN, arXiv ID, ISSN, ADS bibcode, or paper URL. NLM journal abbreviations, the year;volume(issue):pages block, and the doi: suffix, resolved from the publisher’s own record.

One identifier per line. We’ll resolve it and return an AMA-style reference. Nothing is stored.
0 / 2,000 characters
Resolving an identifier confirms the paper exists - it does not confirm the citations in your bibliography point to the right papers. The dominant AI-fabrication pattern is a real, resolvable DOI paired with an invented title. Audit your whole reference list for fabricated citations before you submit.
Each resolved identifier produces one reference in AMA format. The journal name comes back as its NLM abbreviation (N Engl J Med, not New England Journal of Medicine), and the numeric block follows the AMA pattern: year, semicolon, volume, issue in parentheses, colon, page range.

Polack FP, Thomas SJ, Kitchin N, et al. Safety and Efficacy of the BNT162b2 mRNA Covid-19 Vaccine. N Engl J Med. 2020;383(27):2603-2615. doi:10.1056/NEJMoa2034577.
Note the AMA conventions: initials without periods, the first three authors followed by et al. (this paper has more than six), the abbreviated journal title, and the lowercase doi: prefix at the end.
AMA style is the citation format of the American Medical Association, defined in the AMA Manual of Style (11th edition, 2020) and maintained by the JAMA Network. It is the required style for the JAMA family of journals and the default at many other medical journals, medical schools, nursing programs, and residency programs across the US.
AMA is a numbered style: references appear in the reference list in the order they are first cited, and in-text citations are superscript numbers. Journal titles are abbreviated per the National Library of Medicine (the same abbreviations PubMed uses), and DOIs are appended with a lowercase doi: prefix. To see how AMA compares with Vancouver, APA, or IEEE for the same paper, use the Citation Style Comparator.
Reading the example above left to right, an AMA journal reference is built from these parts:
| Part | Example | Convention |
|---|---|---|
| Authors | Polack FP, Thomas SJ, Kitchin N, et al. | Surname + initials, no periods inside initials; all listed when six or fewer, first three then et al. when seven or more |
| Article title | Safety and Efficacy of the BNT162b2 mRNA Covid-19 Vaccine | As the publisher registered it, followed by a period |
| Journal | N Engl J Med | NLM abbreviation, italicised in print |
| Year;Volume(Issue) | 2020;383(27) | Semicolon after the year, issue in parentheses |
| Pages | :2603-2615 | Full page range after a colon |
| DOI | doi:10.1056/NEJMoa2034577 | Lowercase doi: prefix, closing period |
Books work too: enter an ISBN and the reference comes back as authors, italicised title, publisher, year, and the ISBN.
.bib file with our DOI to BibTeX converter and pair it with the bibliography style your journal’s template specifies.This page uses the public API’s builtin AMA formatter. Send POST /api/format with style: "ama" and one or more identifiers in text; batch input returns one reference per line. The builtins vancouver, apa, ieee, and cse work the same way, and 10,000+ further styles are available by CSL id. See the API documentation.
AMA style is the reference format of the American Medical Association, defined in the AMA Manual of Style (11th edition, 2020). It is the house style of the JAMA Network journals and is required by many medical journals, medical schools, and residency programs. References are numbered in the order they are first cited, and in-text citations appear as superscript numbers.
Authors come first as surname plus initials with no punctuation inside the initials, then the article title, the NLM journal abbreviation, then year;volume(issue):pages, and finally the DOI with a lowercase doi: prefix — for example N Engl J Med. 2020;383(27):2603-2615. doi:10.1056/NEJMoa2034577.
Yes. It uses the NLM (PubMed / Index Medicus) journal abbreviation carried on the registry record — New England Journal of Medicine becomes N Engl J Med. When a journal has no abbreviation on file, the full journal title is used instead.
The generator follows the AMA Manual of Style (11th edition) rule exactly: when a paper has six or fewer authors, every author is listed; when it has seven or more, the first three are listed followed by et al. This differs from Vancouver/ICMJE references, which list the first six before et al.
Yes. Paste a PMID or PMCID and the tool resolves it via PubMed, then formats the record in AMA style. DOIs, ISBNs, arXiv IDs, ISSNs, and ADS bibcodes work the same way — enter one identifier per line to build a whole reference list at once.
Compare AMA output against other styles side by side with the Citation Style Comparator, or export the same references to a reference manager format.
This page is a front end for the public Scholar Sidekick API — the same AMA formatting runs over plain HTTP, so you can call it from a script, an AI agent, or your reference manager. Light use needs no key at all. A free account issues an ssk_ key that raises your rate limit.
