Whisper Web
Whisper Web is a browser-based speech recognition platform that leverages OpenAI's Whisper AI model to deliver fast, accurate transcription directly in the user's web browser. It utilizes WebGPU and WebAssembly to process audio locally on the device, ensuring that no data ever leaves the user's machine. The platform supports over 100 languages with automatic language detection and offers three audio input methods: microphone streaming, file upload, and URL/audio capture. Transcriptions can be exported in multiple formats including TXT, SRT, VTT, and JSON. The free tier allows on-device transcription of files up to 200 MB or 20 minutes in length, with no account required and full offline functionality once the model is downloaded. For users needing to transcribe longer or larger files, Whisper Web Unlimited provides cloud-powered transcription for files up to 10 hours or 5 GB, with batch uploads of up to 50 files, priority processing, and cross-device transcript syncing. The Unlimited plan is priced at $10 per month when billed annually. Privacy is a core feature; in the free plan, all processing stays local, and in the paid plan, uploaded audio is deleted after transcription. The platform is built to be accessible across desktop and mobile browsers that support WebGPU, with no software installation or API keys required. Its use of state-of-the-art AI combined with local processing makes it suitable for users who prioritize both performance and confidentiality.
