Aiko

Aiko turns recorded meetings, lectures and voice memos into text for people who want to keep their audio on their own device. It processes completed recordings rather than live speech and doesn't identify individual speakers.

• Audio and video transcription: Transcribe imported files or recordings made in the app, including MP3, M4A, WAV, MP4 and MOV.
• Multilingual text: Transcribe languages including Chinese, Ukrainian, Arabic and Spanish, or translate speech into English; getting both outputs requires separate passes.
• Transcript exports: Save results as SRT subtitles, JSON or CSV for editing or use in other applications.
• Apple Shortcuts: Connect transcription to recording workflows, Notes and Finder Quick Actions, with batch processing available through Shortcuts rather than built into the app.

Aiko is a paid app for macOS, iOS and visionOS. Whisper runs on the device, and the app doesn't upload audio for transcription. The Mac app uses Whisper's large model; iOS uses the medium or small model according to available memory. Processing speed depends on device performance and available resources.

Accuracy varies by language, and recordings that mix languages aren't reliably supported. You need another app to edit transcripts. Aiko doesn't accept Ogg files, and the iOS app must stay open during transcription.
