What they are

Cleanvoice

Cleanvoice is an AI audio editor that detects and removes filler words, mouth sounds, stutters, and dead silence from podcast and voice recordings. Podcasters, solo creators, and interview hosts upload audio files and get a cleaned version back without manual editing. Processing is asynchronous, so you submit a file and return when it is done. The per-minute pricing model means light users pay less, but heavy producers can hit costs quickly.

Sonix

Sonix is an automated transcription service that converts audio and video files into text using AI, then lets you search, edit, and export transcripts in multiple formats. Journalists, podcasters, researchers, and video producers use it to speed up post-production workflows. Transcription accuracy is solid for clear audio but drops noticeably with heavy accents or poor recording conditions. There is no free tier, so you pay from the first minute.
