Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.

Verify every reference against real academic databases — and find the sources you're missing
Paste a claim or paragraph and Citely returns matching academic papers with verified metadata, ready to cite in APA, MLA, or Chicago style.
Submit a reference list and Citely tests each entry against scholarly databases, marking entries that cannot be confirmed or that point to the wrong work.
Citely targets the specific errors AI models make when inventing references, including chimera citations, invented DOIs, and citations that drift across years.
Checks run against CrossRef, PubMed, arXiv, and OpenAlex, so verification reflects real indexed scholarship rather than a single narrow database.
