Before you start

Research,
answered.

Where does the research data come from?

Reddit threads with every comment, Trustpilot reviews, YouTube comments, Hacker News, Quora, and Amazon, App Store and Google Play reviews. One key and one format for all of them.

Who counts the topics?

You do, or your agent does. Monocrawl returns every post, comment and review as data. Count them with a few keyword rules like the ones on this page, or connect Claude or ChatGPT over MCP and ask for the top themes with quotes.

How is this different from a survey?

Nobody is prompted. You read what buyers already wrote when they were deciding, complaining or switching, so the reasons are in their words and the volume is as big as the market.

Can I research any product or category?

Yes. Search any brand, product or problem on Reddit, then add reviews from Trustpilot, Amazon, the App Store or Google Play for the companies involved.

How many comments can I read?

As many as the threads have. Comments come a page at a time, so read the top of a thread or keep paging until it ends.

Can my AI agent do the research?

Yes. Connect it over MCP and ask your question in plain English. It searches, reads the threads and reviews, and answers with quotes.
