Ask for: a variable font explorer

October 4, 2026

Today’s “ask for what you want”: a simple one-page web app to explore all the para­me­ters of a super­cool vari­able font. (Font not linked because I might use it for some­thing and I don’t want to give it away yet.) Vari­able fonts offer tons of expres­sive potential, but, in my usual design setups — Photoshop and/or a block of CSS — I find it dif­fi­cult to explore the “possibility space”. In fact, I barely use vari­able fonts at all, mainly for this reason!

But I found this par­tic­ular font super compelling, if a bit confusing … so, I asked an AI agent to make me a little one-page app, not for exploring any/all vari­able fonts, but for this one in par­tic­ular.

The process was fast, simple, and revelatory: tin­kering with the para­me­ters, even ani­mating them, I was able to find my way to the look I wanted. Pretty cool.
