How we grade them

|---|---|---|
| Value for money | BPlus is $89.99 a year on the US App Store, about $7.50 a month, the low end of this category, and it lifts the caps on questions, documents and file size altogether. Pay monthly and it's $14.99. The wrinkle: the website sets Plus prices per visitor, so web checkout may not match. | CScholar is $12.99 a month or $99.99 a year (about $8.33), and Premium is $14.99 a month, all from the App Store listing. Mid-range for the category. |
| Free plan and trial | CYou can use it without making an account at all. The caps are the ordinary sort, though: 2 documents and 20 messages a day, files of 120 pages or 10 MB, folders of 5 files. One evening of reading and you're done. The better model is kept for Plus. | DA free trial is offered, but its length and whether it needs a card are not stated on the pages read. |
| Features | CChat beside the page with clickable citations, folders to ask across files, YouTube and website links, flashcards, slides, a writer. The gaps are the listing's own, and they sit in the research half: paper summaries are built from abstracts, and full-paper chat only works on open-access papers. | CNotes, summaries, flashcards, quizzes, tutor chat and live lecture recording. It is built for studying, not for scholarly search or citations, and the difference between Scholar and Premium is not stated. |
| Ease of use | BNo store rating on record, so the B rests on the listing: open the site, drop in a PDF, start asking, no account needed. Folders and saved history are the only parts that want you signed in. | CNo store rating on record, and you upload or record material before it gives you anything. |
| Platforms and integrations | AWeb, Mac, Windows, iPhone and Android, plus a developer API. Flashcards export to Anki, Quizlet and Brainscape, slides to PowerPoint, writing to Word or Markdown. | BWeb, an iOS app and a Chrome extension, connecting to YouTube and Vimeo. No Android or desktop app is listed. |
| Best for | quick answers from a PDF, no sign-up | turning lectures and files into study notes |

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.
