About Aiko
Aiko is an AI-powered audio transcription application designed specifically for Apple devices, including macOS, iOS, and visionOS. Developed by Sindre Sorhus, Aiko leverages OpenAI's Whisper model running locally on the device to convert speech into text efficiently. The app supports audio in over 100 languages, making it a versatile tool for users from diverse linguistic backgrounds. Aiko emphasizes privacy by performing all transcription on-device, ensuring that sensitive recordings never leave the user's device.
The app offers high-quality, on-device transcription suitable for meetings, lectures, interviews, and more. It integrates with Apple's Shortcuts app, allowing users to automate transcription workflows. Aiko is a Universal Purchase, meaning a single purchase grants access across all supported Apple platforms. The free trial via TestFlight provides full access for 14 days without limitations, after which users can purchase the app from the App Store to continue using it.
Technical details: Aiko utilizes the Whisper large v2 model on macOS and the medium or small model on iOS, depending on available memory. While the app does not include built-in batch transcription, users can achieve this functionality through custom Shortcuts shared by the developer. The transcription output may occasionally lack punctuation; the developer provides tips for fixing this via external tools like ChatGPT.
Aiko is ideal for anyone needing accurate, private, and on-device transcription on Apple devices, from students and professionals to journalists and researchers. Its support for a wide range of languages and integration with system shortcuts enhances its utility in various scenarios.
