Why Charla
The questions you're thinking. Our answers.
Not a chatbot
Your students talk to real people — friends, baristas, colleagues. Charla records and analyzes those real conversations. No AI partner. No scripted dialogues. Real speech, real mistakes, real progress.
Not just ChatGPT
Any student can paste a transcript into ChatGPT. Charla captures audio natively, transcribes verbatim (preserving every mistake instead of auto-correcting), scores pronunciation, and tracks patterns across weeks — not a one-off chat.
You stay in the loop
You assign the missions. You see the results. You decide what to focus on next session. Charla doesn't replace you — it gives you data you never had before.
On consent and privacy
Charla requires both speakers to consent before every recording. Audio is processed and deleted — only the transcript and analysis are stored. GDPR-compliant. EU-hosted (Paris).
