Model availability can change as providers update or retire services. The conversion screen shows the models currently selectable for your account and language.
Can I stay on the free tier forever?
Yes. Standard voices are free to use, with no fixed document-length limit and no hidden fees.
When do I need credits?
Only when you choose a Premium voice (ElevenLabs, Gemini, etc.). Standard voices are always free. You can switch tiers on any conversion.
Will conversion stop if I close the browser?
When your account has any credit balance (above 0), you can submit a background job and close the browser — conversion continues on our servers. We'll email you when it's done, and the audio is available to download from My Jobs or your inbox for 7 days. Background conversion itself doesn't use extra credits.
