Is Phantom: Lofi Tutor safe?
Phantom: Lofi Tutor sends selected saved chat text to an AWS Polly demo page for voice playback.
When you use voice playback, the extension takes the selected saved chat message and opens a hidden ai-service-demos.go-aws.com Polly page. Its content script writes up to 3,000 characters of that message into the page's form and triggers audio generation, then returns the resulting audio URL to the extension.
