Which one is for you
Pick Brave Search if
- Fits if you want web search that does not profile you
- Works for developers who want a search API with their own web index
Look elsewhere if
- Skip it if you need peer-reviewed papers, because it searches the open web
- Not for you if you hate ads, as free results carry them and removal costs $3 a month
- Watch out: the Search API is separate, at $5 per 1,000 requests, and asks for a credit card even for the free credits
- Too light for managing sources or citations, since it has neither
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

Worth knowing
Brave Search
- It searches the open web, not scholarly databases, so it does not filter to peer-reviewed papers or manage citations.
- Free results include ads; removing them needs Search premium at $3 a month or $29.99 a year.
- The Search API is a separate product: $5 per 1,000 requests, or $4 per 1,000 plus $5 per million tokens for Answers, with up to $20 of free credits monthly.
- The API requires a credit card even for the free credits, which the vendor says is an anti-fraud check.
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
Brave Search
- Independent index
- Results come from an index Brave built itself, not from a pass-through to Google or Bing, according to the vendor.
- Ask Brave
- Combines an AI chat answer with a results page, so you get a summary plus sources and can ask follow-up questions.
- No profiling
- The vendor says it does not collect personal data to profile searchers, and its search ads are anonymous and marked.
- Ad-free option
- A paid Search premium subscription removes ads from the results pages.

- Search API
- A separate developer API returns web, news, image and video results and LLM-ready page context, billed from prepaid credits.
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.
