Frequently asked questions
What's the difference between Free and Premium?
Free scores you locally — pitch and word accuracy run in your browser. Premium adds phoneme-level scoring (which exact sound in which word slipped) and detailed pronunciation tips, so you know what to fix next.
Does my audio leave the browser?
On the Free plan, no — pitch detection and transcription run locally with Whisper. Premium phoneme scoring sends short audio clips to our server for analysis and discards them after.
Which YouTube videos work?
Any video with English subtitles (manual or auto-generated). Manually-captioned videos give the cleanest phrase splits and the best pronunciation feedback.
Can I cancel anytime?
Yes. Cancel from Manage subscription in the extension. You keep premium access through the end of the paid period.
Will more languages come later?
Pro users get early access when we add languages. We're starting with English so we can ship phoneme scoring well before broadening.
