■ FAQ
‣ Can I edit the text in the app?
I don't plan to support any editing. Export the transcription and edit it in a proper text editor.
‣ Why is the app so large?
The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small.
‣ Why is the transcription so slow?
The app favors accuracy over speed. However, performance is expected to improve in the coming months.
‣ Why must I keep the iOS app open while it transcribes?
iOS apps are fundamentally restricted from operating in the background for extended periods.
‣ Can I delete some of the languages to save space?
This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages.

This is an incredible, yet simple app built around OpenAI’s Whisper model. As expected from Whisper-Large, the transcription is incredibly accurate, even in challenging conditions where I myself can’t pick up what someone is saying from across the room. I use the app to voice record lectures, before summarizing them either myself or with ChatGPT or Apple Intelligence’s Writing Tools. It has already proven invaluable and way more reliable than manually writing notes, and I capture every detail required
Perfect!

Near flawless in a 3-party talk with one person on the phone, in 2 different languages. And all that safe and sound locally on devive. Hats off! Maybe one nice extra feature would be a marker for who is speaking, like <person 1> etc.
Simple and functional

Very happy with the app, the simplicity got me into voice notes in the first place. I use it for drafting notes and prose. Note to dev: let us connect OpenAI to summarize/refine our finished notes with prompts!
Aiko is top notch!

Great functionality and as far as I can tell in a ‘privacy friendly’ way. Another nice thing: there is a MacOS version as well. Still can’t believe that this was a free app when it first came out. Kudos!
- The app now requires iOS 26.
- Improved performance.
