Elicit vs Consensus vs a paper search API: which do you actually need?
Published September 26, 2026
Elicit and Consensus are finished products: you type a research question and an AI assistant reads papers and answers. A paper search API is a component you build products with. They are often compared because they touch the same literature, but they are not substitutes. Details are as of September 2026 from Elicit's public pricing page and third-party reviews of Consensus; verify current terms with each vendor.
The short version
- Use Elicit or Consensus if you want to ask research questions and get synthesised answers, extract data into tables, or run a literature review — no code needed.
- Use a search API like OpenAbstracts if you are building something: a chatbot that cites real papers, a writing tool that verifies references, a RAG pipeline, or an assistant integration.
What they publish
Elicit describes itself as an AI research assistant. Its pricing page lists a free Basic plan, Pro at $49 per month ($588 per year), Scale at $169 per month ($2,028 per year) and a custom Enterprise plan; it advertises unlimited search across more than 138 million papers, report and extraction limits that grow with the plan, and API access from the Pro tier upward.
Consensus is an AI-powered research search app. Third-party pricing reviews report that API access is an Enterprise-plan feature with custom pricing and no self-serve developer key; Consensus's own pricing page did not list API details when we checked, so confirm with them directly.
How they differ from a search API
| Elicit / Consensus | OpenAbstracts | |
|---|---|---|
| Who it's for | Researchers and students using an app | Developers building products |
| Output | Synthesised answers, reports, extraction tables | Raw, citable search results (metadata, abstracts, snippets, links) |
| Pricing | Monthly subscriptions per person | Pay per request; 100 free searches/month, then $1.50 per 1,000 |
| API | Higher tiers / sales-led | Every account, self-serve |
| Your own AI | You use their AI | You choose your model and prompts |
Why developers pick an API
- Control. You pick the model, the prompt and the UI, and keep the user relationship.
- Cost shape. A per-seat subscription doesn't fit a product with many end users; per-request pricing does.
- Grounding. You get the actual records, so you can enforce "cite only what was retrieved" — see adding real citations to a chatbot.
Why you might still want an app
If you are one person doing a literature review, an app is faster than writing code. Elicit's extraction workflows and Consensus's answer synthesis are products in their own right. A search API doesn't summarise or generate — it hands you sources.
Using both
Nothing stops you from using an app for exploration and a search API inside your product. If you run Claude, the MCP connector gives it the same kind of literature access directly.
