Public metadata first
DOI lookups use CrossRef, ISBN lookups use Google Books when reachable, and websites are checked through public page metadata.
Built for citations you can check before copying
CitationGen is a free academic writing tool. Its main job is to turn real source metadata into formatted citations while making the source trail visible.
No invented fields
If a source does not expose an author, date, DOI, page range, publisher, or URL, the page shows a warning instead of silently filling it.
Editable before copying
The citation is generated from fields you can review and edit, which is safer than only editing the final formatted text.
Style-specific checks
Science and medical formats can use NLM journal abbreviations where a trusted match is available.
