Recordings / Podcasts / Files / Photos
2

Listen again, use read-aloud, look up words, and switch to bilingual display when you need it.
Listen and read without rushing past
3
Organize and keep
Turn key points into summaries and mind maps, then review, revise or export to share.
Make the content your own notes
Your content, your choice
Local first. Cloud by choice.
Recordings and imported files are saved on your device by default. When you use cloud transcription, translation, AI organization or cloud read-aloud, the necessary content is sent to the respective service providers.
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.
Use cases
Start from one concrete need.
Each page walks through one scenario in full: how to do it, what to watch for, and where Aiotto helps.
