User Roles & Thread Limits

On our Free AI Text-to-Speech platform, each user role comes with a different limit on how many threads can run simultaneously. Threads help process your text requests in parallel, resulting in faster conversions.

  • Un-signed-in User: Maximum of 5 threads.
  • Signed-in User: Maximum of 10 threads.
  • Donor: Maximum of 20 threads.

The more threads you can run, the quicker (and smoother) your text-to-speech requests will complete—especially if you regularly handle multiple conversions at the same time. If you’re looking for the fastest experience, becoming a donor unlocks the highest thread limit.
