Citation tools that just work
A small collection of focused, no-signup tools for the tedious parts of citation work. No limits, no upsell modal, no login required. Powered by the same citation engine that runs DEEPNOTIS.
Citation Generator
Generate a formatted citation in APA, MLA, Chicago, Harvard, or any of 2,800+ styles. No signup.
DOI → Citation
Paste a DOI. We fetch the metadata from CrossRef and give you the citation in five styles plus BibTeX.
BibTeX Formatter
Clean up and validate a messy .bib file. Fixes common syntax errors, normalizes field order, preserves your keys.
Deduplicate References
Paste your BibTeX or RIS. We find duplicates using fuzzy matching on title, author, and year — and hand back a clean list.
LaTeX Bibliography Builder
Paste DOIs. Get a ready-to-drop-in .bib file plus the exact \bibliography{} snippet for your LaTeX document.
Need more than a single citation?
Upload a .docx and DEEPNOTIS reads every footnote or endnote, labels it, and enriches it — then exports the whole document in any citation style.
