What is Speech to Text?
Speech to Text is a free, private and offline audio-to-text transcriber that turns audio recordings into written text using OpenAI Whisper — running entirely on your device via WebGPU/WASM, with no upload. No audio ever leaves your computer; the model is downloaded once and cached. Supports many languages, outputs SRT subtitles, and works offline once loaded — ideal for confidential interviews and meetings.

Frequently asked questions
Does my audio get uploaded to a server?
No. Transcription uses OpenAI Whisper running in your browser via WebGPU and WebAssembly. Your audio never leaves your device.
What audio formats are supported?
MP3, WAV, M4A, OGG, FLAC, and most other formats the browser Audio API can decode.
Does it work offline?
Yes — after the Whisper model downloads on first use (around 150 MB), transcription works without an internet connection.
How accurate is the transcription?
Whisper is among the most accurate open-source transcription models. Accuracy depends on audio quality and language; clear speech in English achieves near-human accuracy.
Is Speech to Text free?
Yes — Speech to Text is completely free with no paywall, trials or usage caps. Every TabTasker tool is free forever.
Does Speech to Text work offline and keep my files private?
Yes. Speech to Text runs 100% client-side in your browser using Web Workers and modern browser APIs. Your files are never uploaded and it keeps working offline once the page has loaded.
Is this speech to text tool better than online tools that upload my files?
For privacy, yes. Most online speech to text services upload your files to a server. TabTasker does everything locally, so nothing leaves your device — ideal for sensitive or confidential documents.
Do I need to create an account or install anything?
No. No account, no extension and no install — just open the page and start. It works on any modern browser, desktop or mobile.
