How we grade them
| 2.6GPAConsensusGood | 2.6GPARayyanGood | |
|---|---|---|
| Value for money | CNobody can put a number on this one. The pricing page didn't show its paid prices on two readings, and Consensus's own pricing summary leaves the dollar amounts out, so it lands where every unpriced tool lands. Pro has 15 Deep Searches a month, Deep has 200, and students get up to 40% off. | BEssential is $4.99 a seat a month billed yearly, and Advanced is $8.33. That's in the cheapest quarter, which starts at $7.50 for the category. Business is $41.67 per license, from 5 licenses. |
| Free plan and trial | CBasic paper search across 400M+ papers is free and the Citation Graph comes with every account, which is more than nothing. But the AI is rationed to 10 Pro messages and 3 Deep Searches a month, so the bit you came for runs out in an afternoon. | BFree forever with 3 active reviews, 2 free reviewers, a sample, duplicate detection and AI relevance predictions. One reviewer can live on that. |
| Features | BIt covers the whole job: plain-language questions answered from their source papers, filters for study type, journal rank and sample size, Deep Search across 1,000 papers, a citation graph, a Zotero library, an API and an MCP connector. Its rivals cover the same ground, mind, several of them screening more papers. | BScreening, duplicate detection, team samples, PRISMA diagrams, PICO extraction and risk-of-bias tools. Nothing in the listing shows a gap in screening itself, but PRISMA and PICO sit on paid plans. |
| Ease of use | BNo store rating on record either way, so this rests on the product: you type a question the way you'd ask a colleague, and the answer comes back with its papers attached. Nothing to connect or configure first. | CNo store rating on record. You set up a review, invite reviewers and run the samples. |
| Platforms and integrations | BWeb and an Android app, with an API and an MCP connector that puts Consensus search inside ChatGPT, Claude and Copilot. It imports from Zotero too. No iOS app was found on the US App Store when it was checked. | CWeb, with a mobile app mentioned but no platforms listed. SSO and API access are Enterprise only, and no integrations are listed. |
| Best for | asking what the studies actually say | screening papers for systematic reviews |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
