What is Audo?
Audo is a web-based toolkit for working on audio and video recordings with AI. The tools fall into five groups: clean-up (an audio enhancer plus noise and echo removal), text (transcription with speaker labels, syncing a script to audio as subtitles, and filler-word removal), editing (cutting, merging, mixing and removing silences), volume (boosting and balancing) and files (format conversion, extracting sound from video and reading file details). Everything runs in the browser, and the site says the tools work with speech in any language. The same functions can be called from AI assistants including ChatGPT, Claude, Codex and Cursor, or from your own application through an API. Use is free for the first part of a file a few times a day, and longer jobs are paid with credits charged per minute. The audo.ai site notes that the earlier Audo Studio product now lives at a separate address.
