A few questions
before you start.

More help
What can I use Aiotto for?

When you listen to recordings or podcasts or read foreign-language material, use it to transcribe (telling speakers apart in conversations), read bilingually, look up words and listen to read-aloud, then take notes with AI summaries and mind maps. Start with one recording or one article.

Do I need to sign in or go online?

Offline transcription needs no account, and local content can be viewed on your device. Podcast catalogs, cloud transcription, online word lookup and AI features need an internet connection. See the app for account and quota requirements.

Can I use it for free?

You can download and try Aiotto for free. Optional monthly and annual Pro subscriptions are available. See the app and App Store for prices, quotas, automatic renewal and cancellation details.

Can I import Bilibili videos?

Yes. Paste a link to a public Bilibili video to import it and follow the transcript as you listen. Whether a video can be imported depends on whether it is public and on the platform’s restrictions. Aiotto doesn’t need, and doesn’t support, signing in to your Bilibili account.

What should I know before importing content?

Only import content you own, have permission to use or may lawfully use. Remote links depend on the source platform, network and access permissions. Aiotto does not support bypassing paywalls, copyright protections or access restrictions.

Free for iPhone, with offline transcription.
