Consensus vs R Discovery

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. R Discovery publishes a starting price ($12); Consensus does not. Both have a free tier.

What our research says

Consensus

Useful when you want to know what a body of literature actually concludes rather than reading one paper at a time, but it orients you, it does not replace reading them.

Pros

  • Every answer is tied to specific papers with study design and sample size
  • Free tier is a standing plan rather than a time-limited trial
  • The yes-or-no consensus meter is a fast orientation device
  • Covers a very large index of peer-reviewed literature

Cons

  • Summaries can flatten real disagreement between studies into false consensus
  • Coverage skews to indexed English-language biomedical work
  • Pricing cannot be verified from outside; the site blocks automated access
  • Free allowance of the deeper analyses runs out quickly in real use

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

Which one fits

Choose Consensus if you need

  • Clinicians and students orienting quickly in an unfamiliar literature
  • Anyone who wants citations attached to every summarised claim

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
  • Non-native English speakers who need abstracts translated
