# Paper Digest review (2026): is it worth it? > Cited literature reviews, deep research and daily paper digests Checked Nov 12, 2026 ยท graded Nov 12, 2026 by ToolGPA. Paper Digest is a web research platform that writes literature reviews and research reports with numbered citations, answers questions about uploaded papers, and sends daily digests of new papers by topic. Its index covers papers, patents, grants, clinical trials and experts. The site says it also offers a literature review mode that does not use large language models. - **Category:** AI Research Tools - **Made by:** Paper Digest (since 2018) - **Website:** https://www.paperdigest.org - **Runs on:** Web - **Who should skip it:** Not for you if you want a price, since the pricing page showed placeholders only. - **Facts last checked:** Nov 12, 2026 ## Pricing Paper Digest's current pricing could not be confirmed from its own site. ## Key features - **Literature review:** Takes a topic and writes a review from the most influential papers, patents, grants and trials around it, with a citation for each sentence. An option avoids large language models. - **Deep research reports:** Gathers evidence from the index and other sources into a cited report, with a claim-verification mode that collects evidence for and against an argument. - **Academic reader:** Upload a PDF or text file, or paste a link, and ask for a summary, the method, the results or any free-form question, answered beside the document. - **Daily and conference digests:** Follows new papers by topic, venue or keyword, including arXiv, bioRxiv, PubMed and ClinicalTrials.gov feeds, and sends daily updates. - **Reference manager export:** Reviews and reports can be exported as RIS or Markdown for Zotero, Mendeley, EndNote and Obsidian. - **Research library:** Members can save documents with notes, tags and reading status, and publish a reading list or researcher profile. ## Good for - Researchers who want every sentence of a literature review traced to a source - People tracking new papers in a field through daily topic digests - Readers who want to question a single paper in plain language ## Worth knowing - No pricing page could be read: the site's pricing URL shows a template table with placeholder values, so no plans or prices are recorded. - The homepage says some features can be tried without signing in and labels several daily digests free, but the limits are not stated. - The default literature review uses large language models for the final prose; the no-LLM version is a separate option. - Only a web version is described; no desktop or mobile app is listed. ## ToolGPA grades **GPA: 2.2 out of 4**, graded Nov 12, 2026. Paper Digest writes cited literature reviews and deep research reports, and sends daily and conference digests. But its pricing page showed a placeholder table with no real plans, the free limits aren't stated, and the default review text is written by large language models. - **Value for money: C.** No price could be read: the pricing URL showed a template table with placeholder values. With nothing to compare against the category's $10 middle, it sits at C. - **Free plan and trial: C.** The homepage says some features can be tried without signing in and labels several digests free, but the limits aren't stated. - **Features: C.** Literature reviews, deep research, a reader, daily digests and reference manager export. The default review uses large language models for the final prose, with a no-LLM version as a separate option. - **Ease of use: C.** No store rating on record. Several separate tools sit on one site and you choose between them. - **Platforms and integrations: B.** Web only, with export to Zotero, Mendeley, EndNote and Obsidian.

That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 31 of the 49 other AI research tools grade higher. - You could make: Documents: an app builder makes this well. - You could not: A library of papers and sources to search. - You could not: An AI model, which you can rent by the request but not make. - You could not: Citation records for millions of papers.
