This text to Speech tool is a BEAST.
Can generate 200,000 characters into AI MP3 in few minutes without any issue. I have not seen such a generous limit in one go!
AI dubbing and Transcription can do 4+ hours of video transcription in a few minutes. Their server seems to be massive.
Text editor can handle very large text to summarize, generate key points or generate blogger outline / press conference.

Glad to have found this gem in appsummo. Nothing can beat them, as far I know.
