why this exists

And a new set of patterns arrived with AI that nobody had written down at all. This library tries to keep both in 1 place, free.

part 1 - the old patterns

They are going missing

I first learnt interaction patterns in Prof. Anirudha Joshi’s lectures at IDC, IIT Bombay - from Martijn van Welie’s pattern collection and Jenifer Tidwell’s Designing Interfaces. They explained not just what a pattern looked like, but the problem it solved and the forces it had to balance.

Much of that is now hard to reach. Sites go offline, links rot, books go out of print. A designer starting today mostly learns patterns by copying a popular app, which teaches the shape of a solution without the reasoning underneath.

part 2 - the new patterns

They were never written down

Streaming answers, citations, approval before an agent acts, a visible plan, a way to stop and take over. These are real interaction patterns with real forces, and teams are inventing them again in every product.

Google’s People + AI Guidebook and Microsoft’s HAX Toolkit are the best public work on this - written as guidelines for teams, not as a library a student can browse. Here both halves sit in the same format, so you can see that Breadcrumbs and Visible plan answer the same question.

part 3 - what is actually here

The library, counted live

Not a promise - the real numbers today. They change every time a pattern is written.

  • patterns named
  • written in full
  • classic
  • from AI products
2 of about 125 planned patterns written in full (2%). Early, and honest about it.
how it stays honest

4 rules this library keeps

  1. 1
    Every number is counted, not typedEach count on this site is calculated from the patterns themselves, so it cannot drift from the truth.
  2. 2
    Unfinished pages say soA pattern that is named but not written shows an honest placeholder - never another pattern's text.
  3. 3
    Examples are dated and creditedEvery example names the product, the company and the month it was checked. Owners can ask for removal.
  4. 4
    No button pretendsIf a feature is not built yet, its button is not there. Every button on this site does what it says.
part 4 - who is writing it
