Frequently asked questions
We've compiled the most important information to help you get the most out of your experience. Can't find what you're looking for? Contact us.
Who is this for?
Product designers working on enterprise software, design system teams, and agencies building B2B products. If you make decisions about UX patterns and want data to back them up, this is for you.
How is this different from Mobbin or Refero?
Mobbin and Refero are screenshot libraries — you browse examples and figure out patterns yourself. Northbase does the analysis for you. We quantify what's common, document microcopy patterns, and provide decision frameworks. We give away screenshots for free; our value is the analysis.
How many patterns are included?
Currently 5 patterns (Empty States, Error States, AI Input, AI Output, Permissions) with new patterns added regularly.
Can I browse before subscribing?
Yes. Individual screen pages are completely free—see exactly how Notion handles empty states, or how Slack designs error messages. Pattern previews show a portion of the analysis free. Subscribe to unlock full analysis.
How do I know the research is legit?
Every statistic is verifiable. All examples are organized and available by system on our platform. You can check our work.
