Dictro is a native dictation application for macOS designed exclusively for Apple Silicon Macs. It enables users to speak naturally in any Mac application, with the app processing speech entirely on the device by default. Dictro records audio while the user holds the Right Option key, transcribes the speech, and then automatically cleans the raw transcription into polished prose before pasting it directly at the cursor position. This workflow eliminates the need for a separate recording dashboard, transcript inbox, or copy-and-paste rituals. The app runs locally unless the user explicitly enables an optional Fast Mode that uses cloud processing. The application includes several features that enhance its utility. Users can add custom words for names and jargon, set app-aware writing preferences, view a visible private usage count, and opt into local transcript history and notes. Dictro offers a full on-device pipeline with unlimited words for local processing, while a premium tier provides fast formatting and priority support. The default weekly word limit is 10,000 words, with unlimited local words available. The app operates in every Mac application and maintains privacy by never sending voice data off the device when using the default on-device mode. Common use cases include composing emails, drafting documents, taking notes, or writing in any text field where typing is slower than speaking. The workflow is simple: hold the Right Option key in any text input area, speak naturally (including filler words and incomplete thoughts), release the key, and the app transcribes and cleans the recording into a ready-to-send or ready-to-edit piece of text. Because all speech recognition and language modeling runs locally, Dictro continues to function without an internet connection, making it suitable for use on airplanes, behind locked-down networks, or in any situation where privacy is a priority. The app requires a Mac with Apple Silicon (M1 or later) and is available through its official website.
