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.
Udio
Udio is an AI music generation tool that produces complete songs, including vocals and instrumentation, from a text description. It is used by content creators, podcasters, indie game developers, and musicians looking for quick backing tracks or original compositions. The output quality is impressive for AI-generated audio, though the tool gives you limited fine-grained control over individual stems or arrangement details.
