Frequently asked questions

How do I send my iPhone Voice Memo to a computer?

Open the Voice Memos app, tap the memo, tap "…", then "Share" → "Save to Files" or AirDrop to your Mac. Then drop the .m4a file into Mictoo on your computer.

Can I transcribe directly on iPhone?

Yes. Open mictoo.com in Safari on your iPhone, tap the upload area, and pick a Voice Memo from the Files app. The transcript appears in seconds and you can copy or download .txt.

What format are Android voice recordings?

Most Android phones save voice recordings as .m4a or .mp3, depending on the recorder app. Both are supported. Some apps use .amr — convert to .m4a first using any free converter.

Is my voice recording private?

Yes. Files are sent to the AI engine for transcription only and never stored on our servers. The transcript stays in your browser and is yours alone.

What if my voice memo is longer than 25 MB?

iPhone Voice Memos use about 1 MB per minute at default quality — so 25 minutes fit in 25 MB. For longer memos, change Voice Memos quality to "Compressed" in Settings → Voice Memos, or split the recording.
