Since 2021, I have used Play ht to help me with my novel writing. Hearing the words spoken helps to identify minor niggles I can address. The quality of ultra-realistic voices are excellent. I had an upgrade to 16000 words per month as I helped provide feedback to various upgrades and reported bugs. I was due for my monthly renewal on the 29th May, but nothing has been credited. It just states Free plan and the message for me to upgrade. I've sent messages to Support and have heard nothing back. This is poor service. A lifetime deal, but not any more. I'm now looking at other options.
