Frequently asked questions
- Who is this for?
- Product designers, product managers, and the engineers who end up making the interface call. Ask it what you would ask a senior designer for clarity: where table filters belong, whether validation fires on blur or on submit, how to run a critique that does not turn into an approval meeting.
- Where does the evidence come from?
- 2,149 cards drawn from 54 published sources: the documentation of design systems like GOV.UK, Carbon, Polaris, Material and Primer, plus research from Nielsen Norman Group and Baymard Institute. Every quote is checked verbatim against the live page it came from, and every answer links back to it.
- How is this different from ChatGPT or Claude?
- A general model like ChatGPT or Claude answers from memory, and sounds equally sure whether or not it has a source. This one answers only from the cards retrieved for your question, cites each by name, and tells you the corpus has nothing on the subject instead of inventing a take. Where sources disagree it gives you the split and the count rather than a manufactured consensus.
