Why use Mictoo?
The fastest way to convert audio and video to text — without paying, signing up, or installing anything.
100% free
No subscription, no trial. Mictoo is free to use with no monthly cap and no minute counting.
Private by design
Files are streamed directly to the Whisper API (Groq primary, OpenAI fallback), processed, and discarded in seconds. We never log, retain, or train on your audio or transcripts.
50+ languages
Automatic language detection. Works for English, Spanish, French, German, Russian, Japanese, and many more.
High accuracy
Powered by OpenAI's Whisper — the same speech recognition model used in ChatGPT and the leading transcription services.
Fast results
A 10-minute audio file is typically transcribed in under 30 seconds. No waiting in queues.
Editable output
Review and edit your transcript right in the browser, then copy to clipboard or download as a .txt file.
AI summary included
After every transcript we generate a free GPT-powered summary with the key points and action items — competitors typically charge $15–20/month for this. No extra click, no upgrade prompt.
Translate to 28 languages
One click translates the full transcript into Spanish, French, German, Japanese, and 24 others. Original timestamps preserved so the translated SRT still matches the audio.

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.
How accurate is the transcription?
Mictoo uses OpenAI's Whisper, 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 — no need to select it.
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 — the limit set by the AI API. For longer files, consider compressing your audio first or splitting it into shorter segments.
What file formats does Mictoo support?
Mictoo supports MP3, MP4, WAV, M4A, OGG, WEBM, FLAC, and MPEG. Both audio and video files are accepted.
How long does transcription take?
Most files are transcribed in seconds. A 10-minute audio file typically takes 15–30 seconds depending on server load.
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.
Do I need to create an account?
No account or signup required. Just upload your file and get your transcript immediately.
What technology powers Mictoo?
Mictoo is built on OpenAI's Whisper API — the same speech recognition model that powers ChatGPT's voice features. Whisper was trained on 680,000 hours of multilingual audio and is widely considered one of the most accurate speech recognition models available.
