What our research says

Elicit

Elicit is the only one of these tools that treats a literature review as a structured extraction job rather than a chat, which is exactly right for the work. The price assumes you are billing someone else for the hours it saves.

Pros

  • Column-per-field extraction into a table is the correct shape for review work and rare elsewhere
  • Free tier is unusually generous: unlimited search, summaries and full-text chat
  • Every claim links back to the paper it came from
  • API access is included from the first paid tier rather than sold separately

Cons

  • The $49 to $169 jump is steep and Scale is priced for institutions, not labs
  • Free tier's limits on the Research Agent and Reports are not quantified anywhere on the pricing page
  • Extraction accuracy still needs spot-checking against the source PDF
  • Coverage is paper-centric, so grey literature and preprint-heavy fields are thinner

PDFdigest

PDFdigest's niche is specific: hand it a research paper and get a narrated video summary back instead of a text digest, aimed at faster comprehension than reading the paper directly. Because the vendor's own site could not be reached during this check - it returned server errors on repeated attempts - the details here rely on secondhand listings and should be confirmed on the live site before relying on them.

Pros

  • produces a narrated video summary, not just a text digest
  • credit packs rather than a locked-in subscription
  • a small number of free daily credits for logged-in users, per third-party listings

Cons

  • the vendor's own site returned server errors on repeated fetch attempts during this check
  • company name and country could not be confirmed
  • credit-pack quantities per tier aren't clearly documented in available sources
