Import what you watch, read, and care about. Constia extracts the phrases that matter to your world and builds your daily practice around them — your topics, your pace, your vocabulary. Not someone else's curriculum.
Why each step works
Review
Spaced repetition moves phrases into automatic memory — not just short-term recall.
Construct
Building sentences from patterns trains production, not recognition.
Input
Real content with scaffolding trains your ear before your mouth.
Shadow
Mimicking native rhythm trains your mouth as a muscle — not just your vocabulary.
Speak
Fluency is procedural. You cannot automate what you never practice under pressure.
