Aiko

Acerca de esta app

Aiko is a transcription application developed by Sindre Sorhus that operates entirely on the user’s device. By leveraging OpenAI’s Whisper model via whisper.cpp, it converts audio from meetings, lectures, and other sources into text without sending data to external servers. The app supports audio in 100 different languages and allows users to export transcriptions as subtitles. A distinctive feature is its word-replacement tool, which automatically corrects common mistakes in the generated text. The developer explicitly states that Aiko favors accuracy over processing speed, resulting in longer conversion times but higher quality output. Unlike many competitors, Aiko does not offer live transcription during recording, nor does it include speaker detection. Users cannot edit text within the app; instead, they are encouraged to export the file and use a dedicated text editor. On iOS, the app uses medium or small Whisper models depending on available memory, while macOS utilizes the large v3 model. Due to iOS restrictions, the app must remain open during transcription. The app requires iOS 26 and is priced at $24.00.
