Stop Studying.
Start Speaking.
Most people spend months in class and still freeze the moment a native speaker responds. That's because no tool has ever shown you what you personally say wrong. Charla does.

Sound familiar?
“I finished 600 Duolingo lessons and still couldn't order coffee in Spanish.”
The false progress trap
“No app has ever told me what I actually said wrong.”
The feedback gap
“My mistakes became habits before anyone corrected them.”
Intermediate plateau
How it works
Three steps. No studying required.
Record any conversation
Hit record before chatting with a native speaker, tutor, or language partner. Charla listens in the background.
See exactly what you said wrong
Every grammar slip and word you reached for but didn't have — highlighted in your own words.
Practice only what you got wrong
Drills built from your real mistakes — not generic textbook exercises that don't match how you actually speak.
What you get
Real feedback. Not a score.
Grammar analysis
Every mistake categorised — ser vs estar, por vs para, gender agreement — with corrections and explanations.
Vocabulary tracking
New words extracted from every conversation with English translations. Mark words as learned.
Mistake patterns
See which grammar categories you struggle with most. Track your top errors across all conversations.
