Hey again 👋

Some things get set and never revisited. Site search, checkout currency defaults, whether the AI is the designer or just the builder.

Here are my three picks this week: the search paradox sending users to Google, what actually separates genUI from vibe coding, and what Stripe found across 1.5M subscription checkouts.

Enjoy 🦄 - Adam at Unicorn Club.

The three picks I'd send to a teammate:

Build: Check your site search against words users actually use, not your own vocabulary

Shape: Ask whether the AI decided what to build or you did before evaluating the output

Ship: See what Stripe found when they tested local currency across 1.5M subscription checkouts

Top 3 this week 👇

Favicon

Build: The Site-Search Paradox: Why The Big Box Always Wins  ↗

Users search with their words. Your site only knows yours.

Why: 50% of users hit search immediately, then leave when it returns nothing for their vocabulary rather than yours.

Adopt: Search your site for a synonym of your top product category and count how many results come back empty.

Favicon

Shape: GenUI vs. Vibe Coding: Who's Designing?  ↗

GenUI is the AI's design call. Vibe coding executes yours.

Why: Who initiated the design determines what quality means: the AI's judgment call, or how well it executed yours.

Adopt: Ask whether the AI decided what to build or you did. The failure modes are completely different.

Favicon

Ship: Testing the Impact of Adaptive Pricing Across 1.5M Subscription Checkout Sessions  ↗

Stripe tested local currency on 1.5M checkouts. Conversion up 4.7%.

Why: In 2025, 80% of subscriptions still charged in the seller's currency. Local pricing lifted LTV per session by 5.4%.

Adopt: Check whether your checkout defaults to your base currency for international visitors.

Dive into more

Build: Applying accessibility fixes with stealth for the greater good  ↗  How to get keyboard focus, ARIA fixes, and accessibility improvements shipped when nobody's asked for them.

Build: When All You Can Do Is All or Nothing, Do Nothing  ↗  Harry Roberts argues that applying loading=lazy or fetchpriority=high to everything in a design system is worse than applying neither.

Build: New to the web platform in March  ↗  Chrome 146 adds scroll-triggered animations, Safari 26.4 lands masonry display, and Chrome 147 beta brings contrast-color() and border-shape.

Shape: Design debt is now as dangerous as technical debt  ↗  Design debt reframed as an AI adoption risk, with a specific audit trigger worth noting before any system review.

Shape: Grammarly shows how prototyping turned into an excuse for not thinking  ↗  Grammarly's AI writer-impersonation feature launched and died in a week. Post diagnoses the pattern: directionless urgency.

Useful Extras

Build: An in-depth guide to customising lists with CSS  ↗  Comprehensive guide to CSS list styling: marker positioning, custom counters, spacing that doesn't break accessibility.

Build: Sprites on the Web  ↗  Josh Comeau on CSS sprite animation for micro-interactions, using Twitter's heart-like animation as a worked example.
