Why Paper Digest?
Based in New York City and serving over 3 million users from thousands of universities, companies, and government agencies since 2018.
Some core services are free
Daily preprint digests, literature search, and all digest articles are free with no account. Most other services can be used without signing in under a daily quota, so patrons can evaluate everything before subscribing.
A citation for every sentence
The literature review generator backs every sentence it writes with a citation, and offers a mode that uses no large language model at all — useful for teaching information literacy and for patrons wary of AI-generated text.
Beyond papers
300 million records across papers, patents, grants, clinical trials, software, and venues, spanning all disciplines, from sources including arXiv, PubMed, bioRxiv, medRxiv, and thousands of journals and conferences.
One platform for the whole workflow
Discover, track, review, read, and write in one place — see all services arranged by research workflow for a one-page overview you can walk patrons through.
Daily digests keep patrons current
Free daily arXiv, bioRxiv, and medRxiv digests, plus the personalized Daily Paper Digest (subscription): daily alerts of papers, clinical trials, and industry news matched to a reader's areas, keywords, and authors — a current-awareness service few other platforms offer.
