What is WhisperUI?

WhisperUI is a web-based speech-to-text tool that leverages OpenAI's Whisper model to transcribe audio files into text and SRT subtitle files. Built by an independent developer, it solves the problem of affordable and accessible transcription by allowing users to bring their own OpenAI API key, paying only for the usage they incur. The core capabilities include drag-and-drop file upload, support for multiple audio formats (MP3, MP4, WAV, OGG, and more), and a clean interface for reviewing and downloading transcriptions. Premium features enable batch uploads, unlimited daily file processing, and SRT generation. The tool is ideal for content creators, journalists, students, and professionals who need quick, accurate transcriptions without a subscription fee. It fits workflows where users already have an OpenAI account and want a lightweight frontend for Whisper. WhisperUI is trusted by members of leading organizations and universities, highlighting its reliability for academic and professional use.
