A UX Field Guide entry with its concept illustration and explanation
What's inside

A whole craft, organised and on hand.

Reference you can actually feel, not just read. Built to be quiet, legible, and quick to scan.

Four pillars, 127 entries

Patterns, Best Practices, UX Laws, and Psychology, including the Gestalt principles. Each entry has a tldr, the why, how to apply it, and a good-versus-bad example.

Interactive demos

Most entries include a small demo you operate yourself. Shrink a tap target, add menu options, anchor a guess, and feel the principle rather than just read it.

Concept illustrations

Every entry carries a monoline diagram that states its idea at a glance, so the library scans by shape, not just text.

Search by meaning

Type what you mean, not the exact words. On-device embeddings rank the most relevant entries, blended with keywords so titles still land first.

Ask, answered on device

Pose a question in plain language and get a short, grounded answer drawn from the guide, with the most relevant entries linked beneath it.

Private and offline

No accounts, no ads, no tracking. The whole guide ships in the app and works with no connection. Search and the assistant run entirely on your device.
