Gio

The travel decoder for Italy.

House rules

A studio is a set of standards, held in public.

We're small on purpose. It's the only way to keep the taste tight and the quality bar where it belongs.

  1. A point of view, not a feature list

    Every app takes a side. Gio isn't a translator — it's a local who has your back. The opinion is the product.

  2. Correct beats clever

    In an anti-scam app, a confident wrong answer is a catastrophe. We'd rather say “retake that” than invent. Honesty is a feature.

  3. Character you can feel

    Voice, texture, restraint. No streaks, no confetti, no app-speak. Made by someone who actually cares how it reads.
