Superwhisper is a dictation tool. You press a shortcut, speak, and the text appears wherever your cursor is, in an email, a document, or a code editor. Because it can run speech recognition models on your own machine, nothing has to be sent to the cloud, which matters for privacy and works without an internet connection.
Modes make it more than plain transcription. A mode can clean up filler words, format the text as an email or meeting notes, translate it, or follow a custom prompt that uses a language model to rewrite what you said. It also understands context from the app you are in, and supports many languages and voice models, including cloud options for higher accuracy.
Superwhisper has a free tier with limits and paid plans, including a one-time purchase option. It is mainly a Mac and iPhone tool, and accuracy depends on the model and microphone. Alternatives include Wispr Flow, MacWhisper, Apple dictation, Talon, and Dragon. Superwhisper suits people who write a lot and prefer speaking.
