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?
Designers and product managers who need confidence in their UX decisions. If you've ever spent 30 minutes explaining a pattern choice without data to back it up, Northbase gives you the reference in seconds. Design system teams and agencies building B2B products use it to make decisions faster.
How is this different from Mobbin or Refero?
Mobbin and Refero are screenshot libraries — you browse examples and identify patterns yourself. Northbase does the analysis for you. We quantify what's common ('9 of 10 systems use X'), document microcopy patterns, and provide decision frameworks. You get data you can reference in a meeting, not just inspiration. Screenshots are free; the analysis is the value.
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. We show our work — all examples are organized by system on our platform. When we say '8 of 10 systems do this,' you can see which eight. That's the kind of claim you can confidently cite in a design review.
