How we grade them
| 2.8GPAR DiscoveryGood | 1.6GPAResearcher.LifeWeak | |
|---|---|---|
| Value for money | BPrime is $69 a year in the US, about $5.75 a month, which lands inside the cheapest quarter of a category that starts around $7.50 and sits nearer $10. An A here wants about $4.50, so it stops at B. It takes the caps off the AI Assistant, Chat PDF and Literature Review, and paying monthly is $12. | 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 for good, no card needed. The day's allowance is 3 AI Assistant uses and 3 Chat PDF uses, with 5 file uploads a month. Fine for a look around. A real reading week runs out by Tuesday, and literature maps and Zotero sync are Prime only. | FNo free plan or trial is listed, only the Prime plan. |
| Features | BA feed matched to your interests, an assistant answering with references from over 300 million papers, PDF chat, a literature review workflow, audio papers and translation into more than 30 languages. Finding and reading papers, covered end to end. Literature Review only runs on a desktop or laptop, though. | 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 | B4.8 on the App Store, but from about 920 ratings, and the top grade wants a thousand behind it. So B. You pick a few interests and the papers come to you. The catch is that Literature Review needs a desktop or laptop. | CNo store rating on record, and several tools to learn behind one account. |
| Platforms and integrations | BWeb, iPhone, Android and a Chrome extension, with Prime syncing your reading lists to Zotero or Mendeley and GetFTR, LibKey and Paperpal wired in as well. There's no desktop app, though, and our top mark wants one. | CWeb only, with no API or integrations listed on the pricing page. |
| Best for | keeping up with new papers on your phone | one subscription for writing and finding papers |

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.
