Which one is for you

Pick Paperguide if

  • Fits if your team runs systematic reviews and needs every screening decision documented
  • Works for students and academics, who get 30% off with a university email

Look elsewhere if

  • Tight if you're staying free, with 20 AI searches and 2,000 credits a month, and no systematic reviews or shared workspaces
  • Pricey if you need dual-reviewer screening, which sits on Evidence at $89 a seat a month billed annually
  • Watch out: every AI feature draws on one monthly credit pool, 12,500 on Plus and 50,000 on Pro
  • Skip it if you were counting on image and table extraction, as that's still marked coming soon
  • Not for you if you want a phone or desktop app, as only a web app and browser extension are listed

Pick Sourcely if

  • Fits if you've drafted an essay and need papers to back it up
  • Works for someone who uses ChatGPT or Claude and wants source search there

Look elsewhere if

  • Tight if you do a lot of searching: 10 deep searches a month on Pro, 30 on Ultra
  • Not for you if you want to know the free limits first, as they aren't on the pricing page
  • Watch out: the free version is mostly English-language sources
  • Watch out: Ultra's monthly price isn't shown, and there's no app

How we grade them

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.
CPro is $9 a month billed yearly ($17 monthly), in the middle of the research range. Ultra is $19.
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.
CA free version exists, but its limits aren't on the pricing page beyond being mostly English-language sources.
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.
CSource finding from text, deep search, summaries, chat, citation export and filters. Deep searches are capped monthly on both paid plans: 10 on Pro, 30 on Ultra.
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.
BNo store rating on record. Paste your text and get sources back, with nothing to set up.
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.
BWeb only, with MCP support for ChatGPT and Claude.

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.
