- Works for researchers who would use the journal finder and skill courses

How we grade them
| 2.6GPAPaperguideGood | 1.6GPAResearcher.LifeWeak | |
|---|---|---|
| Value for money | CPlus is $12 a seat a month billed annually, or $19 monthly, which is the middle of this category exactly. It does carry systematic reviews of up to 1,000 papers, unlimited AI searches and 12,500 credits a month, and a university email takes 30% off. Dual-reviewer screening is another matter: Evidence, at $89. | CPrime is $12 a month, between the category's $10 middle and $14 dearer quarter. The $144 shown beside it is not clear, and multi-year is $9 a month for 3 years. |
| Free plan and trial | CFree gives you 2,000 AI credits and 20 AI searches a month, 500 MB of reference storage and extraction tables of up to 10 papers and 5 columns. Enough to learn the tool, not to run a project on: there are no systematic reviews and no shared workspaces. | FNo free plan or trial is listed, only the Prime plan. |
| Features | ATwo parts rivals like Elicit and Consensus don't list: screening that ends in a PRISMA diagram with dual-reviewer checking, and a full reference manager with 1,000-plus citation styles. Then AI search across 200 million papers, extraction tables, an agent and a writer. | CLiterature recommender, writing assistant, illustration tool, journal finder and courses. A bundle of separate tools, so each does less than a product built for that one job. |
| Ease of use | CNo store rating on record, and the work is front-loaded: a protocol to define for screening, columns to set up for extraction, and one monthly credit pool that every AI feature draws on. It does import a Zotero or Mendeley library, so your references don't start from nothing. | CNo store rating on record, and several tools to learn behind one account. |
| Platforms and integrations | BA web app with a browser extension, plus a Search API at 10 requests a month on Free and 500 on Pro. It imports from Zotero and Mendeley and connects to Claude and ChatGPT. No phone or desktop app is listed, so that API is what earns the B. | CWeb only, with no API or integrations listed on the pricing page. |
| Best for | search, references and reviews in one workspace | one subscription for writing and finding papers |

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.
