Elicit vs Otio

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

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
