■ Common Questions

Does it work completely offline?
Yes. Your audio never leaves your device. Works on flights, in remote areas, anywhere.

Can I transcribe WhatsApp voice messages or videos?
Yes. Share or save audio/video from WhatsApp to Whisper Notes and transcribe offline. Perfect for extracting subtitles without uploading to cloud services.

Is there a recording time limit?
No limit. Record for hours if you want. Longer recordings just take more time to transcribe on your device.

Does it support real-time transcription while recording?
Not during recording, but yes during transcription—after you finish recording, you'll see the transcript appear in real-time as it's being generated.

Where is my data stored?
Only on your device. We have zero access. Note: If you delete the app, your recordings are deleted too (because we don't keep secret backups). Please export important files regularly.

Why no AI summaries?
Privacy. We never upload your recordings to any AI service. Want summaries? Copy the transcript and use your preferred AI tool. We don't lock your data into a proprietary system.

Why does transcription stop when I switch apps?
iOS limits background GPU usage for third-party apps. Just return to the app and tap "Re-transcribe"—it will restart.

What languages are supported?
100+ languages including: English, Deutsch, Español, Русский, 한국어, Français, 日本語, Português, Türkçe, Polski, Català, Nederlands, Arabic, Svenska, Italiano, Bahasa Indonesia, Hindi, Suomi, Tiếng Việt, Hebrew, Українська, Greek, Bahasa Melayu, Čeština, Română, Dansk, Magyar, Tamil, Norsk, Thai, Urdu, Hrvatski, Bulgarian, Lietuvių, Latina, Māori, Malayalam, Cymraeg, Slovenčina, Telugu, Persian, Latviešu, Bengali, Српски, Azərbaycan, Slovenščina, Kannada, Eesti, Macedonian, Brezhoneg, Euskara, Íslenska, Armenian, Nepali, Mongolian, Bosanski, Kazakh, Shqip, Kiswahili, Galego, Marathi, Punjabi, Sinhala, Khmer, chiShona, Yorùbá, Soomaali, Afrikaans, Occitan, Georgian, Belarusian, Tajik, Sindhi, Gujarati, Amharic, Yiddish, Lao, Uzbek, Føroyskt, Kreyòl Ayisyen, Pashto, Turkmen, Nynorsk, Malti, Sanskrit, Luxembourgish, Myanmar, Tibetan, Tagalog, Malagasy, Assamese, Tatar, Hawaiian, Lingala, Hausa, Bashkir, Javanese, Sundanese, 简体中文, 繁體中文
