Describe your thesis, claim, or research question. Citation Kitchen queries five databases in parallel, scores each candidate, and streams the top matches as they arrive — with supporting quotes and pre-formatted citations.
Every candidate source gets a numerical match score against your question, ranked highest first.
Each source arrives with a quoted passage that shows exactly why it fits your claim.
CrossRef, Semantic Scholar, OpenAlex, PubMed, and arXiv searched simultaneously — the combined coverage your library subscribes to, but unified.
Every discovered source ships with a pre-built citation in the style you picked — drop it straight into your bibliography.

Type your thesis, claim, or research question — a sentence is enough. Pick a citation style and how many sources you want back.
Your query fans out across CrossRef, Semantic Scholar, OpenAlex, PubMed, and arXiv. Candidates are scored by topical relevance and quote fit.
Top-ranked sources stream back with supporting quotes and pre-formatted citations. Copy, paste, cite — bibliography done.
Discovery is the main thing: feed a question, leave with a bibliography. Verification is the sidekick — useful when you've already written something and want to audit the references.

Discover mode is unreal for lit reviews. I described my thesis topic and got fifteen relevance-ranked sources with supporting quotes and pre-formatted citations inside a minute. It would have taken me a full day in the library.
Amara T.
PhD Candidate, History
I was staring at a blank page with no idea where to start. Typed my research question, got back a ranked bibliography with quotes showing exactly why each source fit. Skipped the week of library crawling entirely.
Sarah L.
Psychology, 4th year
I use Discover to build the bibliography, then hand the paper back to Verify before submission. One tool covers the whole arc — from blank page to defensible reference list.
