What is WhisperUI?
WhisperUI is a speech-to-text and text-to-speech product built around OpenAI models. Its core transcription flow lets you upload audio files in the browser, send them to OpenAI Whisper, and review the resulting text or subtitle output for download.
The product also includes a desktop app for local transcription on Windows and macOS, plus a set of free browser tools for converting transcript and subtitle formats, cleaning rough exports, and estimating transcript length. Pricing pages show both cloud and local workflows, with a paid subscription available for desktop access and cloud usage.
