WhisperUI

WhisperUI is a web-based and desktop application that converts spoken language into written text using OpenAI’s Whisper automatic speech recognition model. Users can upload audio recordings in common formats such as mp3, mp4, mpeg, mpga, m4a, wav, ogg, and webm, with a file size limit of 25 MB per upload. The interface allows drag-and-drop or browse file selection, and after processing, the service returns a transcript of the audio content. WhisperUI is designed for individuals who need quick, accurate transcription without requiring technical expertise in machine learning or API integration. It can be used for transcribing meeting notes, lecture recordings, podcast episodes, voice memos, interviews, dictations, and any other spoken content that needs to be turned into searchable, editable text. The platform supports English and multiple other languages that OpenAI Whisper handles, though the exact language detection and output depend on the underlying model. Users have the option to work with their own OpenAI API key, which means they pay directly to OpenAI for the computation cost, while WhisperUI provides the interface and convenience. For those who prefer a simpler experience, the service also offers premium plans that include built-in API usage, allowing transcription without managing an external key. The FAQ section addresses common questions about free usage limitations, premium features, API key security, and file compatibility. WhisperUI is particularly suitable for freelancers, students, researchers, journalists, and small business owners who need to process occasional audio files but do not want to commit to expensive enterprise transcription services. The desktop version provides offline or local processing capabilities, though details on offline functionali
