Frequently Asked Questions

Is Whisper Web really free? Do I need an account?
In free local mode, audio is processed in your browser and is not uploaded. No account is required. Each file can be up to 20 minutes and 200 MB. There is no daily file-count limit. For longer files, Whisper Web Unlimited offers optional cloud processing with a per-file limit of 10 hours and 5 GB.
What is the official Whisper Web site?
The official Whisper Web site is https://whisperweb.dev. Other domains may use a similar name. Free local mode on whisperweb.dev runs in your browser without an account; each file is limited to 20 minutes and 200 MB.
Does my audio leave my device?
In free local mode, audio is processed in your browser and is not uploaded. Model files still download over the network the first time you use a model. Whisper Web Unlimited is an optional cloud workflow for larger files (up to 10 hours and 5 GB per file).
What if a result says Whisper Web but the address is different?
If a result says “Whisper Web” but the address is not whisperweb.dev, it is not the official Whisper Web site. Open https://whisperweb.dev to use free local transcription in your browser (20 minutes / 200 MB per file, no account).
How accurate is free speech to text conversion?
Accuracy depends on the spoken language, selected model and recording quality. Noise, overlapping speech and specialist terms can cause errors. Review important names, numbers and quotes against the original audio.
Is this speech to text tool really free?
Yes — local mode is completely free with no account required. Unlike TurboScribe (free: 3 files/day, up to 30 min each, upload required — turboscribe.ai/pricing, checked 2026-10-28) or Otter.ai (Basic: 300 min/month, 30 min per conversation, 3 file imports total; Pro: $16.99/user/month billed monthly — otter.ai/pricing, checked 2026-10-28), Whisper Web runs the AI entirely on your device with no daily cap on files.
Can I use my microphone for speech to text online?
Yes. Click the microphone button to record directly in your browser. Your browser will request microphone permission once. Recording supports clips up to 60 seconds, with transcription starting automatically when you stop. Ideal for dictation, note-taking, and quick voice memos.
Does speech to text work offline without internet?
Yes. After the initial Whisper model download (~40 MB for Base, ~150 MB for Small), speech to text runs fully offline. The model is cached in your browser, so subsequent visits work without any internet connection — unlike cloud services that require constant connectivity.
Is my speech data private and secure?
All processing happens locally in your browser via WebGPU or WebAssembly. Free files are processed locally and are not uploaded. Unlimited adds optional cloud upload. This makes Whisper Web suitable for confidential content: medical dictation, legal recordings, private meetings, and HIPAA-sensitive workflows.
What languages does the free speech recognition support?
Whisper supports 100+ languages, including English, Spanish, Mandarin, French, German, Japanese, Korean, Arabic, Hindi, and Portuguese. Automatic language detection identifies the spoken language, or you can manually select it for optimal accuracy.
