Paper Digest
What Paper Digest is
Paper Digest is a web-based AI research platform for reading, writing, answering questions, and discovering literature. Its literature review service identifies influential papers, patents, grants, and clinical trials, then creates linked reviews from indexed sources. Free Literature Search covers 300 million records across papers, patents, grants, clinical trials, venues, and software. Users can receive customized daily updates from sources including arXiv, PubMed, bioRxiv, medRxiv, ClinicalTrials.gov, conferences, and journals. Paid services add an academic PDF reader for uploaded documents and sentence-level academic writing, editing, and citation support. Reviews and research reports can be exported as RIS or Markdown. A literature-review mode can avoid large language models and produce English-only output. Free daily quotas are five review jobs, ten rewriting jobs, and ten question-answering jobs; paid memberships have no daily limit for these services. Plans start at $6.66 a year (annual billing).
