Which one is for you
Pick Silvi if
- Fits if you're running a literature review alone and want the basics free
- Works for a small team of up to 5 that wants AI screening and extraction
Look elsewhere if
- Pricey if you want AI screening or extraction, which need Plus at €19 a month
- Tight if you work with others, since multi-reviewer workflows are paid
- Watch out: prices are in euros, and monthly-billing prices didn't show on the page
- Watch out: a Rapid plan is in the table with no price, and there's no app
Pick Undermind if
- Fits if your question is too tangled for keyword search to find the right papers
- Works for academics, who pay $16 a month on annual billing against $60 for industry
Look elsewhere if
- Pricey if you work in industry: Pro is $60 a month billed annually ($75 monthly), and Team is $60 a seat from 3 seats
- Tight if you're staying free and need full texts read, since free searches cover abstracts and metadata only
- Not for you if you want an answer in seconds, as a deep search takes about 2 minutes
- Watch out: the free plan's rate limits have no published numbers, and charges aren't refunded once a billing period starts
- Skip it if you want a phone or desktop app, or writing tools, as it's a web app for searching
How we grade them
| 2.6GPASilviGood | 2.2GPAUndermindFair | |
|---|---|---|
| Value for money | CPlus Individual is €19 a month billed as €230 a year, near the top of the research category, whose dearest tenth starts at $20. A team of 5 is €55 a month. | DPro at the academic rate is $16 a month billed annually, or $20 monthly, which already puts it in the dearest tenth of a category whose middle is $10. Industry is another world: $60 a month billed annually for the same Pro, five times the dear end here. |
| Free plan and trial | BBasic is free with unlimited reviews and the core import, screening and extraction functions. One person can really live on that. | CFree covers chat, deep searches, reports, shared workspaces and agent connections. The rate limits are only described as standard, with no numbers given, and free searches read abstracts and metadata rather than full texts. |
| Features | BImport, screening, highlighted extraction, AI extraction, team workflows and tables. The AI parts and multi-reviewer workflows are paid, but the core review job is covered. | CA deep search reads and ranks hundreds of papers from a database of over 200 million, follows citation trails and comes back with a report carrying in-line citations, then chat, custom tables and alerts. Searching is all it does: no reading tools, no writing. |
| Ease of use | CNo store rating on record. You set up a review and import studies before it does anything. | BNo store rating on record, so B is the ceiling. There's nothing to configure, though: describe what you're working on in plain language, answer a few follow-up questions, and it goes off to read. Then you wait, because a deep search takes about 2 minutes. |
| Platforms and integrations | BWeb, with PubMed, OpenAlex, ERIC, Zotero, Mendeley, EndNote and Web of Science. | BA web app, with an MCP server so Claude, ChatGPT, Cursor, VS Code and Copilot can run Undermind searches for you, and that's included on the Free plan. No phone or desktop app is on the listing. |
| Best for | screening and extracting data for literature reviews | hard questions keyword search can't crack |

Worth knowing
Silvi
- Prices are in euros, and the monthly figures shown are the yearly-billed rate; monthly and quarterly billing exist but their prices did not show on the page.
- The pricing table also lists a Rapid plan with no price displayed.
- AI screening, AI data extraction, multi-reviewer workflows and in-app chat support are not on the free Basic plan.
- The Plus Team plan covers 5 seats.
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
Silvi
- Study import

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.

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.
