Audio Converter AI
Audio Converter AI is a browser-based audio studio that turns recordings, videos, and social links into editable transcripts, then layers text-to-speech, YouTube tools, and format conversion in the same workspace. Upload MP3, WAV, M4A, MP4, and other common formats, paste a YouTube or TikTok URL, or record in the browser. Transcripts ship with speaker labels, timestamps, and AI summaries you can search or export.
Most transcription apps stop at speech-to-text. Audio Converter AI stretches one credit balance across transcription minutes, AI summary chat, premium voice characters, and file conversion, so you are not juggling separate subscriptions for captions, narration, and MP3 exports. The Growth and Professional tiers even lift minute caps on transcription while keeping upload limits up to 5 GB per file.
Students use it to turn lectures into study notes, creators repurpose podcasts and webinars into posts, and teams convert meetings into labeled transcripts they can share. The site runs in any modern browser on desktop or mobile with no desktop install.
