What You Can Ask

Find what's already worked on a page like yours

“What are the biggest significant wins on checkout pages for sales, from tests with at least 10,000 visitors?”
  • A ranked list of tests with effects, p-values and sample sizes
  • Links to each test and its pattern on goodui.org

Check the evidence before you build a test

“We want to add testimonials to our pricing page. What does the GoodUI evidence say?”
  • The matching patterns, with their verdict, median effects per metric and repeatability
  • The combined effect across all their tests, so one lucky result doesn't mislead you

Run your own meta-analysis in one question

“Combine tests 421, 314 and 590 on sales. What's the pooled effect and how confident can we be?”
  • One weighted effect and p-value across the tests you chose
  • Each test's effect and weight, so you can see what drives the result

How It Works

Get your key

Team and Company members request a personal key. We send it to you, usually within a business day.

Add GoodUI as a connector in Claude, or in any AI tool that supports remote MCP servers. It takes about two minutes.

Ask in plain language

Your assistant searches patterns and tests, ranks results and runs meta-analyses for you.

Common Questions

  • What is MCP?

    MCP (Model Context Protocol) is an open standard that lets AI assistants use outside tools and data. With GoodUI's MCP server connected, your assistant can look up GoodUI patterns and A/B tests directly instead of guessing from what it learned in training.

  • Which AI tools does it work with?

    Claude (desktop and web) via a custom connector, and other AI tools that support remote MCP servers with an API key in a request header. We'll send setup steps with your key.

  • Does GoodUI see my conversations?

    No. We only receive the requests your assistant sends to GoodUI, such as a search term or a test number, never your prompts or the rest of the conversation. We log those requests to run the service and keep usage fair; see our Terms of Service.

  • Are there usage limits?

    MCP access is for your team's own research and experiment planning, under fair use. Normal use, even heavy use, is fine. Bulk downloading or copying the dataset isn't. Details are in our Terms of Service.

  • Can we build GoodUI data into our own product or AI model?

    Not with a membership. That needs a data license, which is available: talk to Jakub.
