|---|---|---|
| Value for money | BPlus is $8 a seat a month billed yearly, or $10 monthly, a bit under the $12 or so these tools usually start at. But the listing can't say how big the weekly usage limit is. Choosing your model and OCR need Pro at $16, and Deep Search needs Max at $80. | APlus is $89.99 a year on the US App Store, about $7.50 a month, or $14.99 monthly. That's unlimited questions and documents, with files of up to 2,000 pages, when tools like this usually start around $12. One wrinkle: the website sets its own prices per visitor, so web checkout may differ. |
| Free plan and trial | BNo card needed, and Zotero and Mendeley connect on the free plan. AI usage refreshes every day, but nobody says how much you get. Each upload tops out at 20 MB or 120 pages, so a long book won't fit. | BYou can try it without even making an account, which we like. But it's 2 documents and 20 messages a day, with files capped at 120 pages or 10 MB. Enough for a paper or two. Not enough for a week of revision. |
| Features | AAsk one file, a folder or your whole library, and each answer opens the exact passage behind it. The agent searches PubMed, arXiv and JSTOR, the note editor suggests citations as you write, and it reads Word, PowerPoint, EPUB, audio and video as well as PDFs. | BChat beside the document with clickable citations, folders for asking across files, YouTube and website links, flashcards, slides and an AI writer. The gap is the paper search: its summaries are built from abstracts, and chatting with a full paper works only for open-access ones. |
| Ease of use | BNo App Store rating on record, so B is as high as we go. Upload your files and ask. The fiddly part is the plans: usage on each one is given as a multiple of another plan's, like 4x Plus or 5x Pro, never as a number. | BNo App Store rating on record, so B is as high as we go. It's hard to get simpler, mind: upload a file and start asking, with no account needed. Folders and saved history want a free account. |
| Platforms and integrations | BWeb, Mac, iPhone and iPad, plus a Chrome extension and an add-in for Microsoft Word. It connects to Zotero, Mendeley, Google Drive, Notion and Slack. But the desktop app is Mac only and there's no Android app. | AWeb, Mac, Windows, iPhone and Android, plus a developer API. Flashcards go out to Anki, Quizlet and Brainscape, slides to PowerPoint, and writing to Word or Markdown. |
| Best for | answers you can check against the page | quick answers from a PDF, no sign-up |
