One engine, every surface you write in. Everything below checks the same way and answers from the same public record — install what fits how you work, skip the rest.
Paste a bibliography, get verdicts. Free, unlimited, no account, and your draft never leaves the browser.
The full kit: the citation record on every major paper page, the free check panel in Overleaf, and — with Pro — continuous checking as you type and the @cite picker.
Search literature, check your bibliography, and (Pro) write citations at your cursor — inside Word. Sideloads in about a minute from the manifest; full instructions on the Word page.
Install instructions manifest: https://citestamp.com/word/manifest.xml
The same check plus literature search, in a Docs sidebar. Distribution lands through the Workspace Marketplace; this line gets an install button when it does.
The citation-health check in your item pane. Download the .xpi, then in Zotero: Tools → Plugins → gear menu → Install Plugin From File. Updates arrive automatically after that.
Download v1.0.3 (.xpi) sha256:50d5f1cb80928cb869527aef40e3d10b3f273d3a4611c60de52b8fe06d535616
Your agent asks the graph before it cites. Streamable HTTP, no SDK required, anonymous reads at 10/min — a free key raises that, a Pro token raises it further.

REST over the same graph: check reference lists at submission time, resolve identifiers, read typed claims. Anonymous 10/min; free keys by email; Pro raises the ceiling to 600/min.
