If what you want to study is not on YouTube, Bilibili, or a podcast platform — a movie, documentary, audiobook, course recording, or foreign-language radio recording you already downloaded, for example — you can upload the file directly to Aelano. Aelano transcribes it, adds subtitles, and you study it the same way you study online content.
Situations where this helps:
Open the Aelano Home page and go to the upload panel, where you will find the "Upload Audio or Video" entry. Tapping it opens your system file picker so you can choose the file to upload.
Aelano supports the vast majority of common audio and video formats.
Video formats
mp4, m4v, mov, avi, wmv, flv, webm, mkv, mpeg, mpg, 3gp, 3g2, ts, mxf
Audio formats
mp3, wav, aac, flac, ogg, m4a, wma, aiff, alac, opus
Ebook formats
epub
If you pick a file that is not on the list above, Aelano tells you the file format is not supported.
EPUB books open in the dedicated book reader rather than using the audio/video transcription flow below. For the table of contents, page modes, translation, and reading styles, see Import an EPUB Book.
Put the file somewhere your system supports — your computer, your phone, or iCloud / Google Drive. Aelano reads it through the system file picker.
Go to the Aelano Home page and tap "Upload Audio or Video" in the upload panel. Your system file picker opens.
Short files take anywhere from under a minute to a couple of minutes. Longer content (a one- or two-hour movie, a lecture of several dozen minutes) takes longer. When transcription finishes, the file appears in your library and you can open it and continue studying any time.
A single audio or video file can be at most 12 hours long. Content longer than that cannot be transcribed as one piece — you need to split it into parts with an external tool first and upload them separately.
Why does my file fail to upload with "file format not supported"?
Your file's extension is probably not on the supported list. Convert it to MP4 or MP3 first with a transcoding tool (HandBrake, FFmpeg, CapCut, and similar), and then upload it.
Why does selecting several files tell me I need a membership?
Single-file upload is available to every user. Batch transcription — submitting several files at once — is a membership feature. If you only upload a file now and then, single-file upload is enough.
What do I do with content longer than 12 hours?
You need to split it into parts with an external tool first — by chapter or by episode, for example — and upload them separately. Each part is transcribed and studied on its own.
Where are uploaded files stored? Will I still see them after switching devices?
Once uploaded, a file goes into your own library, and other users cannot see it.
I cannot find iCloud or My Files in the file picker on iOS / Android.
In the file picker you usually need to tap "Browse" or the menu icon in the top-left corner to switch to iCloud Drive, Google Drive, Files, and so on. This is system behavior, and it can look slightly different on each device.
