Suggests heading and body font pairings, and locks the one you like.
Generates heading, subheading and body combinations from the Google Fonts library using a similarity model, with a slider from 'very similar' to 'very different' and a lock on any font you have already chosen. It is a starting point rather than an authority — you still have to look at the result at real sizes with real words. Everything runs in the page.
Questions
Works the moment the page loads. No account, no email, no trial. It only pairs Google Fonts, and it judges letterform similarity rather than whether the pairing suits your subject.
No. Fontjoy does the work inside your browser, so the file never leaves your device — you can load the page, disconnect from the network, and it still works. That makes it a reasonable choice for material containing personal data.
