How can we help?

Start with a public YouTube lesson; PDF, Word, PowerPoint, images or text files; pasted text; or a live recording. In Files, choose Audio file to import one MP3, WAV, M4A, OGG, WebM or FLAC of up to 50 MB and three hours. Documents and audio use separate imports. Files also supports RTF, ODT, ODP and readable UTF-8 text with an unfamiliar extension. Each Study Set keeps its source available for reference.

No. You choose only the methods you want: notes, flashcards, multiple choice, fill in the blanks, a written test, a Tutor Lesson, or a Podcast. You can customize supported methods before generation.

Yes. Acedra builds each method from the source attached to that Study Set. The source and transcript remain available alongside your learning material for reference.

Once your upload finishes, preparation continues in the background and you can return through your library. Finish and save a recording before leaving: active microphone capture cannot survive closing or reloading the page. Progress percentages describe preparation stages, not remaining time. A connection message appears if live updates are interrupted.

Explore is a public catalog of ready-to-study, source-grounded guides. It is useful when you want to start learning immediately without uploading your own source.

Your personal sources and Study Sets are private to your signed-in workspace. Public Explore guides are separate from material you add yourself.

Acedra adapts to the amount of distinct material. Brief or repeated passages do not need a long episode or several lessons. Tutor prepares later lessons as you progress, and its course map shows which are ready. You can request preparation of the remaining course when available.

Use the plus button to attach up to four private files, 10 MB and 20 pages each; attached audio can be up to ten minutes. The microphone records up to two minutes. Finish recording to transcribe automatically, then edit the text before sending. Chat attachments help answer your message without changing your study methods.

Acedra prepares long sources in resumable sections and keeps progress visible in your library. You can choose a focused PDF page range when the full document is not relevant to your goal.

Open the Study Set from your library. Acedra preserves the source and any completed methods, explains which stage failed, and shows a retry action only when that action is safe.

The Podcast player becomes available only after its audio is ready. Raise Hand is then enabled from the player so you can pause the episode and ask a source-grounded follow-up without losing your place.

Yes. After you add the video, Acedra opens method selection while transcript preparation continues in the background. Your choices start automatically when the source is ready.
