What they are
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.
Podcastle
Podcastle, recently rebranded as Async, is a browser-based audio and video production platform aimed at podcasters and solo creators. It handles remote recording, AI-powered noise removal, transcription-based editing, and voice cloning in one workspace. The free tier covers basic recording but caps exports and AI features. Paid plans start around $11.99 per month, making it competitive with dedicated tools like Descript for audio-first workflows.
