Hey again šŸ‘‹

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 šŸ¦„ - 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 šŸ‘‡

Favicon

Build: The Site-Search Paradox: Why The Big Box Always Wins  ā†—

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?  ā†—

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  ā†—

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  ā†—  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  ā†—  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  ā†—  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  ā†—  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  ā†—  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  ā†—  Comprehensive guide to CSS list styling: marker positioning, custom counters, spacing that doesn't break accessibility.

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