Aiko is an AI-powered audio transcription tool that enables users to convert audio to text easily. The app ensures complete privacy by performing transcription directly on the user's device. Powered by OpenAI's Whisper model, Aiko supports transcribing audio in 100 languages. It allows users to work with audio and video files, offering export options to various formats like JSON, CSV, and subtitles. Aiko is designed for simplicity in audio transcription, with additional support for Shortcuts. For advanced users, MacWhisper is an alternative tool by the same developer, providing enhanced iOS performance through CoreML and batch conversion capabilities.

Aiko focuses on privacy and encourages users to edit transcriptions in external text editors due to the app's privacy-focused design. Despite dividing transcriptions by sentences, users can use ChatGPT for prompt-based punctuation adjustments or paragraph division. While lacking live transcription and diarization features currently, the developer plans to address popular user requests. Compatible with macOS and iOS, Aiko allows easy transcription through drag-and-drop functionality or sharing from apps like Voice Memos and Telegram.
