AI Whisper (OpenAI Whisper) — Browser-Based Speech-to-Text, Free, Local & Unlimited

Experience AI Whisper — an advanced OpenAI Whisper model running entirely in your browser. Convert speech to text quickly and securely with no installation, no registration, and no time limits.

Everything happens locally on your device — audio is never uploaded to a server, keeping your data fully private. Whisper uses powerful AI speech recognition to transcribe MP3, WAV, M4A and other formats with exceptional accuracy.

Choose your preferred language and Whisper model (tiny, base, small, medium, or large), and get your transcript instantly. The tool is completely free and continues to work offline after the model has been downloaded once.

Use AI Whisper online for podcasts, interviews, meetings, voice notes, or research — all locally, privately, and without limits.

⚙️ All computation happens right in your browser — files are not uploaded to a server. The model and required assets are cached locally, so subsequent runs are faster. The more powerful your computer (especially the GPU), the faster the transcription.
💡 Model — the “brain” that recognizes speech. Bigger models are more accurate but take longer. For quick results, use tiny or base.
🎧 Chunk length — the duration of an audio piece processed at once. Shorter chunks show progress more often; longer chunks can be slightly faster and more accurate on long recordings.
💻 Backend — how computations are executed. WebGPU uses your graphics card (faster), WASM uses only the CPU. Auto picks the optimal option for you.
