Superwhisper is the power-user's transcriber that grew into an iOS keyboard. mmumble is iPhone-first and casual by default

Where Superwhisper is genuinely good

• Local-first transcription on Mac for users with strong privacy preferences
• BYOK and custom prompt modes for users who want to tune the output themselves
• Long-form transcription where you want maximum control over the result
• Power users who like configuring tools

Where mmumble is a better fit

• Less configuration pressure. Install mmumble and rely on one keyboard behavior, instead of learning a mode system to land the writing style you want.
• Casual register as the default, not a setting. mmumble is tuned around messaging and social writing first, professional output second.
• iPhone-first from day one. Superwhisper added an iOS keyboard on top of a Mac-first product. mmumble was designed around the iOS keyboard surface from the start.
• Built around how non-developers actually talk. Half-sentences, slang, music names, film names, without configuring a custom mode.

The test

Same phrase, said to each one. Proper nouns are where most dictation falls apart, and this line is proper nouns all the way down.

"I went to Oneohtrix Point Never at the Barbican Centre last night and it was unreal"
