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

Illuminate

A free way to turn a dense paper into a short listenable summary or an interactive study guide, backed by Google's own research and voice-synthesis work rather than a smaller vendor. Being a Labs experiment rather than a shipped product means feature scope and availability can shift, and a waitlist can still gate access in some regions.

Pros

  • Free to use rather than a paid research tool
  • Produced by Google's own Labs and research teams rather than a third party
  • Now covers both audio summaries and interactive study guides under one product

Cons

  • Being a Labs experiment, features and availability can change without the stability of a shipped product
  • Rolled out gradually with a waitlist in some regions rather than open to everyone
  • Requires a Google Account to use, no anonymous access

Which one fits

Choose Elicit if you need

  • Researchers screening hundreds of abstracts against defined inclusion criteria
  • Pharma, policy and academic teams that need an auditable trail back to sources

Choose Illuminate if you need

  • Researchers and students wanting an audio summary of a dense paper before reading it in full
  • Learners who prefer an interactive study guide over a static document
