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.
