Consensus vs Otio

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. Otio publishes a starting price ($7); 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

Otio

Otio's real differentiator is scale: chatting across hundreds of documents with real page-level citations instead of the handful of files most chat-with-PDF tools cap out at. Keeping every core feature, including all models, Deep Research, and citations, available on every paid tier and charging only for volume is a fair pricing structure. It's a research tool specifically, not a writing tool, so it pairs well with something else for the drafting stage.

Pros

  • Handles hundreds of sources in one persistent workspace, not per-session uploads
  • Citations link back to the specific page, not just the source document
  • All AI models and Deep Research are available on every paid tier
  • Supports many source types: PDFs, videos, articles, transcripts

Cons

  • Free plan is capped at 50MB total storage, which fills up fast with PDFs
  • Research only, with no built-in writing or drafting workspace
  • Higher tiers gate mainly on volume, so heavy users pay significantly more
