Humm is a desktop AI speech-to-text application that converts spoken words into text directly on a user's computer. It is designed for people who want to dictate messages, documents, notes, and other content without relying on cloud-based transcription services. Its main differentiator is local-first processing: recordings are transcribed on the device, and the application can work offline. Users can activate dictation using a keyboard shortcut and have the resulting text inserted into the active application. Optional cloud transcription models can be connected using the user's own API key
