Interviews & journalism
Turn recorded interviews into searchable text without sending sensitive audio to a cloud API or waiting in a queue.
ブラウザで無料かつプライベートに音声をテキスト化。ファイルをアップロードし、Whisper でローカル文字起こし。サーバーへのアップロードは不要です。
No subscription for this tool. Transcribe audio, voice, or URLs with OpenAI Whisper models running client-side.
Your audio is not uploaded to our servers for transcription. Processing stays on your device in a Web Worker.
Start immediately — no account, no API key. Ideal for one-off files, quick memos, or trying speech-to-text privately.
Three steps from audio to text — all local after the model loads.
Upload a file, record with your mic, or paste an audio URL — depending on which free tool you use.
Pick source language and a Whisper model size. Quantized models load faster on most devices.
Read the transcript on the page, copy to clipboard, or export TXT / JSON — your text, your workflow.

Turn recorded interviews into searchable text without sending sensitive audio to a cloud API or waiting in a queue.

Convert class recordings and study MP3s into notes you can skim, quote, and archive — free and on your device.

Draft show notes or meeting minutes from audio files. Export TXT or JSON when the transcript is ready.
Built for people who cannot send sensitive audio to the cloud.

Common formats such as MP3, WAV, WebM, M4A, and more work in modern browsers. Drop a file or browse to upload — transcription runs locally with Whisper.
Very long files depend on your device memory and CPU. For best results, split extremely long recordings or use a smaller Whisper model with the quantized option enabled.
No sign-up is required for this free browser tool. Open the page, add audio, and transcribe — no login for local transcription.
Cloud tools usually upload your audio to their servers. Whisper AI’s free tool runs the model in a Web Worker in your browser, so your file is not sent to us for transcription.
Yes. These pages are free to use with no paywall for local browser transcription. Optional paid plans apply to the Chrome extension and cloud features, not this on-page Whisper tool.
For these free tools, speech-to-text runs locally in your browser. We do not upload your audio to our servers for transcription. URL mode fetches the file from the link you paste; that request goes from your browser to the host.
