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

R Discovery

R Discovery is built around the daily habit of keeping up with a field: it recommends papers based on what you've already read, then lets you interrogate a PDF instead of skimming it cold. The free tier is usable on its own, but the features researchers actually want, literature review drafts and unlimited PDF chat, sit behind the $12/month Prime plan.

Pros

  • Personalized paper feed based on reading history across a large index
  • Chat directly with a paper's PDF instead of just searching its abstract
  • Generates a first-draft literature review from selected papers
  • Audio playback for papers, useful for reading on the move

Cons

  • Heavier AI features (literature review, unlimited PDF chat) require the paid Prime tier
  • Recommendation quality depends on how much reading history the account has built up
  • No API for pulling data into other research tools

  • Pharma, policy and academic teams that need an auditable trail back to sources

Choose R Discovery if you need

  • Researchers who want a personalized feed of new papers in their field
  • Skimming a paper's findings via chat before deciding to read the full text
