Fontjoy

Fontjoy does one narrow thing and does it quickly. The core loop is three controls: Generate produces a fresh heading-and-body pairing, Lock pins the font you like so it survives subsequent generations, and Edit opens a manual selector when you already have half the pair in mind. Editable sample text matters more than it sounds — type your actual headline in and you immediately see whether a display face holds up at real word lengths, which is where most pairing tools fall down because they only ever show pangrams. The stated goal is sound typography reasoning: fonts that share an overarching theme but carry a pleasing contrast. Approaching that with a neural net rather than a curated list means you get combinations outside the handful of pairings that circulate on every design blog. The honest constraints are about scope. Everything comes from the Google Fonts library, so if your brand uses a licensed or custom typeface, Fontjoy cannot help you place it. There is no CSS or design-tool export, no account, and no saved projects — close the tab and the pairing is gone unless you wrote it down. The interface is deliberately bare, with no search or filter across the font library, which means manual Edit selection is browse-and-hope rather than query. It is also not built for print, where exact font metrics and licensing detail matter. Where it fits: the first thirty minutes of a web project, a landing page you are prototyping, or a founder who needs a credible heading/body pairing without hiring a typographer. Where it does not: teams who need a shared, versioned type system, anyone working outside Google Fonts, and anyone who needs the pairing to travel into code automatically. The font visualizer and logo maker are useful side doors if you want to see a face in isolation or take the pairing into a quick mark. Pair Fontjoy with Typewolf for real-world examples and with Google Fonts itself for weights and subsets, and the workflow covers the gap it leaves.
