What is Sonix AI?

Sonix AI converts audio and video files into text transcripts automatically, supporting over 49 languages. The tool uses machine learning to transcribe speech, then lets you edit transcripts, generate subtitles, and search within your content. It's designed for journalists, podcasters, researchers, content creators, and businesses who need accurate transcriptions without manual typing. The freemium model means you can test it with a small amount of free processing before deciding whether to upgrade.
