Dia quick start

A sample conversation between Dia and a learner.

A casual chat about your weekend

Dia

Hey Maya, big question: what'd you actually do this weekend? No filters.

Honestly I just stayed in. I was trying to make sourdough but it didn't rise much.

Classic. Was it the starter or the proof time you think?

Maybe the proof. The kitchen was kinda cold.

Yeah, cold proofs are tricky. Pro tip: stick the bowl in the oven with just the light on.

Oh that's smart. I'll try that next weekend.

Perfect. You used 'kinda cold' just now. Want me to flag that as casual register so you keep using it correctly?

Speaking as Maya from Portland

Tell Dia who you are
Pick your target language and dialect, your level (beginner, intermediate or advanced), and one thing you'd like to talk about today. Dia adapts to what you say.
Have a 5-minute conversation
Talk about your weekend, a problem at work or a movie you watched. Dia asks follow-up questions and rephrases what you got wrong.
Review your word bank
The words you use go into your word bank so you can review them later.
Rotate dialects when you plateau
Once you are comfortable with, say, Mexican Spanish, try Spanish from Spain for a week.

Gentle corrections. When you slip, Dia shows a better way to say it, then the conversation keeps going.
Dialect-aware. Mexico or Spain Spanish, US or UK English, Mainland or Taiwan Mandarin, each with its own voices and idioms.
Speaking first. Every session is a conversation.
Session memory. Dia remembers your level, your recent struggles, and the topics you care about.
Your language when you need it. When you're stuck, Dia can switch to your language, then pick the conversation back up.
