Why text-form voicemails are objectively better
Speed: reading a 200-word voicemail takes ~30 seconds; listening to it takes ~90 seconds. Across 5 voicemails per day, that's 5 minutes saved daily, ~30 hours per year. Context-shifting: reading doesn't require headphones, doesn't bother people around you, doesn't fail in noisy environments. Searchable archive: the converted Markdown lives in your notes vault, grep-able for "what did the lawyer say about the deadline last month". Forwardable: a text voicemail is paste-able into Slack, email, or a task manager. An audio voicemail isn't.
Where the audio comes from
iPhone Visual Voicemail saves audio files locally that can be exported via Files → save to Files → upload. Most carrier voicemail systems can email voicemail audio as an attachment (M4A or MP3) when configured to. Google Voice exports voicemail as MP3 directly from its web interface. Skype, RingCentral, Vonage, and most VoIP services have one-click "download voicemail" options. Whatever the source, the result is a short audio file; MDisBetter takes any of them.
Honest scope
This is a one-off conversion tool — drop a voicemail file, get the text. If you want automatic voicemail-to-text on every incoming voicemail, that's a feature your carrier or VoIP provider offers (most do, often called "Visual Voicemail Plus" or "Voicemail Transcription"). MDisBetter fills the gap for voicemails that arrived without auto-transcription, voicemails saved from years ago, or voicemails where the carrier's transcription was wrong and you want a higher-quality re-transcription with structured output.
