Audio to Text — Transcribe Voice Locally with Whisper

Private speech-to-text: Whisper in your browser

Why transcription is a privacy problem

Audio is uniquely sensitive: it carries not just words but voices, emotions, and background sounds that reveal where you are and who is with you. Most transcription services ask you to upload the recording to their cloud — meetings, medical notes, interviews, and voicemails all passing through someone else's servers.

This tool takes the opposite route. Whisper — the same model family behind many commercial transcription APIs — runs inside your browser tab as WebAssembly. The audio stays on your device from first byte to final text.

What you can use it for

• Meeting and lecture notes — turn a recording into searchable text.
• Interviews and podcasts — draft show notes or quotes without a typing service.
• Voicemails and voice memos — archive them as text.
• Subtitles — export SRT with timestamps for your own videos.

Accuracy tips

The tiny model favors speed; speak clearly and minimize background noise for best results. If a clip is in a specific language, selecting it explicitly (instead of auto-detect) reduces errors on short recordings. For very long recordings, splitting them first keeps each run manageable — our Audio Cutter tool can do that locally.
