Inter is a free, open-source typeface designed by Rasmus Andersson and purpose-built for screen reading. It's optimized for legibility at small sizes and ships with a generous set of OpenType features — tabular numbers, contextual alternates, a slashed zero, and stylistic sets — that components can opt into when the design calls for it.

Inter covers more than 100 languages with full Latin, Cyrillic, and Greek glyph sets, so Claudio reads natively across every region Flywire serves. Distributed under the SIL Open Font License — no licensing fees, no attribution requirements, no surprises.
