A SMALL, SPONSORED TRIAL
Space to try it.
No payment setup.
Each invitation includes 30 AI requests and up to 10 minutes of connected Voice Coach time. The extension shows what’s left. Recording feedback can use more than one request.
Voice access is also limited to 20 connections and 60 coach replies. Closing the Coach ends the session; muting keeps it connected. If a connection fails unexpectedly, reserved time may need to be restored by your host.
What is sent when I use AI?
The selected captions, your question, and recordings you choose to submit are sent through the trial server to OpenAI. Voice Coach streams microphone audio during the conversation. The trial server stores allowance records, not recordings or conversations. Saved words and notes stay in your browser.
Can I use this on my phone?
This trial is for desktop Chrome. The download page works on a phone, but the extension needs a computer.
Something didn’t work. What should I send back?
Tell your host which feature you tried, what you expected, and what happened. A screenshot and the video link are helpful. Don’t share a private recording or your trial code publicly.
