Both of those prices strike me as quite high, given that Whisper can be run relatively quickly on commodity hardware. It's not like the bandwidth is significant either, it's just audio.
It’s based on a finetuned Whisper and you’d get unlimited transcriptions for $4.99/month
It has great quality transcription from video and audio (in English only sorry if that's not you!). Uses Whisper.cpp plus VAD to skip silent / non-speech sections which introduce errors normally. Give a try let me know what you think! :)
