Value for money
BPlus is $12 a seat a month billed annually, or $19 monthly, which is right at typical. It includes systematic reviews of up to 1,000 papers, unlimited AI searches and 12,500 AI credits a month. A university email takes 30% off, making it $8. Dual-reviewer screening is another matter: that's Evidence at $89.
BAt the academic rate, Pro is $16 a month billed annually or $20 monthly, a little over typical for the category. It adds full-text analysis, the newest AI models and 10x higher usage limits. The industry rate is another world: $60 a month billed annually for the same Pro.
Free plan and trial
BFree 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. There are no systematic reviews or shared workspaces on it, though.
BFree includes chat, deep searches, reports, shared workspaces and agent connections, which is a lot of the product. But its rate limits are only called standard, with no numbers given. And free searches cover abstracts and metadata, not full texts.
Features
ASearch that answers from more than 200 million papers with each claim linked to its source, a reference manager with more than 1,000 citation styles, tables that pull the same data points out of many papers, a research agent and a writer. The systematic review workflow ends in a PRISMA diagram.
AA deep search reads and evaluates hundreds of papers from a database of over 200 million, follows citation trails and comes back with a report whose statements carry in-line citations. Then you can chat with an assistant grounded in those papers, build custom tables and get alerts when new work is published.
Ease of use
BNo App Store rating on record, so B is as high as we go. You ask in plain language, and it imports a Zotero or Mendeley library, so starting is painless. Credits are the thing to learn, since the AI features all draw on one monthly pool.
BNo App Store rating on record, so B is as high as we go. You describe your research in plain language and answer a few follow-up questions. Then you wait: a typical deep search takes about 2 minutes, so it isn't instant.
Platforms and integrations
BA web app with a browser extension. It imports from Zotero and Mendeley, connects to Claude and ChatGPT, and has a Search API with 10 requests a month on Free and 500 on Pro. No phone or desktop app is listed.
BA web app, with an MCP server so Claude, ChatGPT, Cursor and VS Code can run Undermind searches for you. Connecting agents is included in the Free plan. No phone or desktop app is on the listing.

Who each one suits

Paperguide

  • Teams running systematic reviews that need documented screening decisions
  • Researchers who want search, references and writing in one workspace
  • Students and academics, who get 30% off with a university email
  • Pulling the same data points out of many papers into one table

Undermind

  • Complex research questions where keyword search misses relevant papers
  • Academics, who pay $16 a month on annual billing instead of the $60 industry rate
  • People who want literature search inside Claude, ChatGPT or a coding agent
  • R&D teams tracking new publications in specific technical areas

Worth knowing

Paperguide

  • The Free plan has no systematic reviews or shared workspaces and is limited to 20 AI searches and 2,000 AI credits a month.
  • AI features draw on a monthly credit pool: 12,500 on Plus, 50,000 on Pro and 150,000 on Evidence.
  • Dual-reviewer screening for systematic reviews needs the Evidence plan, at $89 per seat / month billed annually.
  • Image and table extraction is marked as coming soon on the pricing page.

Undermind

  • Free-tier searches read abstracts and metadata only; full-text search of open-access papers and preprints needs Pro.
  • Industry pricing is far higher than academic: Pro is $60 a month billed annually against $16.
  • A deep search typically takes about 2 minutes to finish, so results are not instant.
  • Charges are non-refundable once a billing period has begun, except where the law requires a refund.

Key features

Paperguide

AI Search
Ask a research question in plain language and get a synthesized answer drawn from more than 200 million papers, with each claim linked to its source.
Systematic reviews
Screens papers against a predefined protocol with cited evidence for each criterion, then produces verified extraction tables, a report and a PRISMA diagram. Dual-reviewer screening is on the Evidence plan.
Reference manager
Imports from Zotero or Mendeley, or by DOI, URL, PDF, BibTeX or RIS, fetches metadata and open-access PDFs, and formats citations in more than 1,000 styles.
Extract Data
You define the columns and the AI fills them across the selected papers, with every value linked to the statement it came from. Tables export to CSV or Excel.
Research Agent
Investigates a topic across the paper database and your library, answers questions about one or several PDFs, and can generate a literature review of up to 50 papers.
AI Writer
Drafts and edits documents with citations from your library and the paper database, and exports them as Word, PDF or LaTeX files.

Undermind

Deep literature search
You describe a research goal in plain language and answer follow-up questions. Undermind then reads and evaluates hundreds of papers and follows citation trails; a typical search takes about 2 minutes.
Reports with in-line citations
Findings come back as a report in which statements carry in-line citations that lead to the source paper, alongside a paper list you can sort and filter to judge relevance.
Chat and custom tables
After a search you can brainstorm with an assistant grounded in the papers it found, extract details from full texts and generate custom tables.
Alerts for new papers
Undermind keeps track of your areas of interest and notifies you when relevant papers are published.
Agent connections over MCP
An MCP server lets assistants and coding agents such as Claude, ChatGPT, Cursor and VS Code run Undermind searches. Connecting agents is included in the Free plan.
Full-text search on Pro
The Free tier searches abstracts and metadata. Pro adds compute to search the full texts of nearly all open-access and preprint articles.
