What is Aiko?
On-device speech-to-text in 100 languages.
Who is Aiko best for?
Aiko is best for Mac and iPhone users who want private transcription of meetings and voice notes on their own device.
Sensitive recordings
It runs OpenAI's Whisper model on the device itself, so interviews, calls and other private audio never leave your Mac or iPhone.
Students and note-takers
It turns lectures, meetings and voice memos into text you can copy out, and can translate the speech into English.
Multilingual audio
It handles audio in about 100 languages, though the maker notes that quality varies from language to language.
Shortcuts users
The maker publishes shortcuts for batch transcription, a Finder quick action on the Mac and one-press recording from the iPhone Action button.
How much does Aiko cost?
Aiko's price is shown only on the App Store, where one Universal Purchase covers the macOS, iOS and visionOS apps, and the maker offers a 14-day free trial of the full app through TestFlight.
The maker's page lists no price and links to the App Store to buy. The TestFlight trial is the full app with no limits and no automatic charge; schools buying 20 or more copies through Apple School Manager get 50% off, and older versions for macOS 13, 14 and 15 are free to download. Plans and current prices are on sindresorhus.com.
