Frequently asked questions
Is Mictoo really free?
Yes. Mictoo is completely free for files up to 25 MB. No account, no credit card, no hidden fees. Signed-in users get a higher 60 MB per-file limit and 7 free transcriptions per day, still with no payment required.
How accurate is the transcription?
Mictoo uses OpenAI's Whisper large-v3, one of the most accurate open speech recognition models available. Accuracy depends on audio quality and accent, but typically exceeds 95% for clear recordings.
What languages are supported?
Whisper supports over 50 languages including English, Spanish, French, German, Portuguese, Russian, Ukrainian, Japanese, Chinese, Arabic, and more. Language is detected automatically, or you can pick one manually in the upload form.
Is my file stored on your servers?
No. Files are streamed directly to Groq's Whisper API (US-hosted) for transcription, with OpenAI's Whisper API kept as an automatic fallback, and are not stored on Mictoo's servers. Neither provider uses API audio for model training; OpenAI retains data for at most 30 days of abuse monitoring before deletion.
What is the maximum file size?
Up to 25 MB anonymously, 60 MB after a free sign-in. Larger files up to 180 MB are auto-split into chunks and merged into a single transcript for registered users.
What file formats does Mictoo support?
Mictoo supports MP3, MP4, WAV, M4A, OGG, WEBM, FLAC, AAC, MOV, and MPEG. Both audio and video files are accepted; for video we extract the audio track server-side.
How long does transcription take?
Most files finish in seconds. A 10-minute audio file typically takes 15 to 30 seconds; a 60-minute podcast is done in about a minute.
Can I edit the transcript after it is generated?
Yes. The transcript is fully editable in your browser before you copy or download it. No account is needed to save changes to your local session.
Do I need to create an account?
No. For files up to 25 MB, you can transcribe without an account. A free account unlocks larger files (up to 60 MB per file, 180 MB via auto-split), history, AI summary, translation to 28 languages, and chat with your transcript.
What technology powers Mictoo?
Mictoo is built on OpenAI's Whisper large-v3 model, served by Groq for speed with OpenAI as fallback. It is the same speech recognition model that powers ChatGPT's voice features and many professional caption services.
