PaperDigest

Paper Digest is an AI-powered research platform designed to help students, researchers, academics, professionals, and organizations discover, understand, track, and work with scientific and technical information. The platform was founded in 2018 by Dr. Chang Wang and is based in New York City. Paper Digest says its services are used by more than 3 million users from universities, companies, and government agencies.

The platform combines academic search, literature analysis, research assistance, document reading, academic writing, question answering, and research-tracking features in one environment. Its research database and knowledge graph cover scientific papers as well as related information such as patents, grants, clinical trials, software, research venues, experts, organizations, and other documents. Paper Digest states that its platform maintains a large, continuously updated corpus containing hundreds of millions of documents.

One of Paper Digest’s main functions is literature discovery. Its Literature Search allows users to search across hundreds of millions of records, while Search Console helps connect papers with related patents, grants, researchers, venues, and other research information. This makes the platform useful for finding relevant material beyond a conventional academic-paper search.

Paper Digest also provides a Literature Review tool for reviewing influential research around a topic. The platform emphasizes citation-supported results and states that its literature-review generator does not rely on large language models for generating the review. According to Paper Digest, citations are provided for the sentences generated by this system, which is intended to make research results easier to trace back to supporting literature.

For more extensive research, the Deep Research feature generates domain-specific reports using scientific literature and other credible sources. It supports areas including academic research, healthcare, technology, and business, while allowing users to specify time ranges and provide their own documents as inputs.

Paper Digest also includes an Academic Reader for working with PDFs and other documents. Users can upload academic papers, essays, patents, grant proposals, clinical trials, reports, and other materials, then ask questions and obtain answers based on the uploaded content. The reader also supports notes, saved documents, saved AI conversations, side-by-side viewing, and multiple languages.

Its Academic Writer extends the platform into academic writing. It provides text generation, citation generation, paraphrasing, rewriting, grammar correction, and sentence-level citation assistance. It can be used for research papers, essays, project reports, literature reviews, grant proposals, blog posts, letters, emails, and personal statements.

Another major part of the platform is its digest system. Users can receive customized research updates through Daily Paper Digest, while Conference Digest summarizes papers from major academic conferences. The Best Paper Digest highlights influential papers from conferences and journals, and Topic Tracking allows users to follow research developments in selected areas. Paper Digest also offers free daily digests for arXiv, bioRxiv, and medRxiv.

Paper Digest is therefore positioned more as a complete academic research environment than as a single-purpose summarization tool. Its combination of literature discovery, research tracking, document analysis, writing assistance, deep research, and citation-focused tools makes it suitable for users who need to move from finding research to understanding and producing research-related content in one platform.

Pricing

Paper Digest offers free services as well as paid subscription services. Free access includes daily digests such as arXiv Daily, bioRxiv Daily, and medRxiv Daily, Literature Search, access to Paper Digest articles and digests, and limited access to some paid features.

For new users, the current paid plans are:

• Annual: $79.90 USD billed every 12 months, equivalent to $6.66/month
• Half-yearly: $47.94 USD billed every 6 months, equivalent to $7.99/month
• Monthly: $10.99 USD billed monthly
• 6-month one-time: $47.94 USD, with no automatic renewal

Paper Digest states that the one-time six-month option is primarily intended for users whose cards do not support U.S. dollar payments or recurring billing.

Review

Paper Digest provides a broad collection of research-oriented features rather than focusing on only one academic workflow. Its strongest area is the connection between literature discovery and research analysis. Users can search academic material, track new papers, review research topics, read uploaded documents, ask questions, conduct deeper research, and receive daily research digests.

The platform is particularly useful for researchers who need to monitor rapidly changing fields. Its Daily Paper Digest and Topic Tracking features can reduce the need to manually check multiple journals, conferences, preprint repositories, and other research sources. Its Conference Digest is also designed to help users quickly scan large numbers of conference papers.

The Academic Reader and Academic Writer make Paper Digest useful beyond literature discovery. The reader can help users work through lengthy PDFs, while the writer combines rewriting, grammar correction, citation discovery, and academic writing support. The platform’s multilingual capabilities also make several of its research and writing functions accessible to users working in languages other than English.

A limitation is that Paper Digest covers a large number of functions, so users looking for a simple single-purpose academic tool may need some time to understand the different services and workflows. Some advanced services are also subject to the paid subscription, although the platform provides free services and limited daily quotas so users can test its capabilities before subscribing.

Paper Digest is best suited to academic research workflows that involve discovering literature, following new developments, reviewing existing work, reading papers, verifying claims, and preparing research-related writing. Its combination of a large research corpus, knowledge graph, digest services, and academic AI tools gives it a broad scope for research-intensive users.
