What is Aiko AI?

Aiko is a high-quality AI-powered speech-to-text transcription app developed by Sindre Sorhus, designed to run locally on Apple devices including iPhone, iPad, and Mac. It leverages OpenAI's Whisper technology to transcribe audio from meetings, lectures, and other recordings into text with a strong emphasis on accuracy over speed. The app supports transcription in 100 different languages and ensures user privacy by processing all data on-device without sending anything to the cloud. Aiko is ideal for users who need reliable, offline transcription without sacrificing confidentiality. It includes features like word replacement to automatically fix common transcription errors and allows exporting transcriptions as subtitles. While it does not support live transcription or speaker detection, it fits workflows that prioritize precise, secure transcription for professionals, students, and anyone working with audio content.
