Who is Sol?
Sol is the language partner who never gets tired of your mistakes.

A conversation with Sol
Can we practice Spanish? I'm really rusty.
Claro — let's keep it easy. Last time you kept mixing up 'ser' and 'estar'. Want to warm up with that, or just chat freely first?
let's just chat, gently correct me
Perfecto. Cuéntame sobre tu día. I'll nudge you when something's off, but mostly just let you flow.
