Reads your actual course material
Turn what you were given into something you understand
Upload the chapter, the slide deck or the lecture recording. Eluna reads it and explains it back step by step, then turns it into notes, a mind map or a practice test you can sit.
No card. Free every day, not just for a week.

What it does with it
One upload, eight ways to work with it
Every tool reads the same file, so you are never re-explaining your own course to a chat box.
Explains it step by step
Ask about any line in the file and get the reasoning, not just the answer. Formulas are typeset properly.
Writes the notes you would have
Structured headings, the key terms in bold, and three questions to check yourself at the end.
Maps how it connects
A mind map built from the material, so you can see which ideas hang off which.
Sets you a real test
Multiple choice, short answer and long answer, marked, with the reasoning shown afterwards.
Transcribes the lecture
A recording becomes a clean transcript plus revision notes, in one go.
Builds the deck
A full slide deck from the material, editable, and it downloads as PowerPoint.
Moves it between languages
Twenty-one languages, keeping the formulas, code and structure intact.
Plans the week before the exam
A day-by-day plan built around your exam date and the hours you actually have.
Three steps
From a file on your phone to something you can revise from
- 1
Bring the material
Drag in the PDF, photograph the page, or drop the recording. Nothing to install.
- 2
Ask it anything about that file
It answers from your material. When something is not in there, it says so instead of inventing it.
- 3
Keep what you made
Notes, maps, decks and transcripts stay in your account, and export as Word, PDF or PowerPoint.

Before you sign up
The things people actually ask
Yes, and it refills every day rather than running out after a week. You get the tutor, notes, practice questions, the planner and the career guide without a card. Every tool shows what you have left before you use it.
PDFs, Word files, PowerPoint, plain text, photos of handwritten pages, and audio recordings up to about fifteen minutes. A scanned PDF has no text in it, so upload those pages as images instead and it reads them with vision.
Used to understand, revise and check your own work, it is no different from a tutor. Submitting its writing as your own breaks almost every academic integrity policy, and we do not help anyone hide that AI was used.
Sometimes, like every AI. It is built to work from your file rather than from memory, and to say when something is not in there — but check anything that matters, especially numbers, dates and citations.
They are stored privately against your account and read only to answer your questions. Delete a file and both the file and the text taken from it go. Nothing is shared with other users.
One click from your account page, which opens the billing page where you cancel yourself. You keep Premium until the end of the period you already paid for, and nothing is charged after that.
Open the file you have been avoiding
It takes a minute to find out whether this helps. No card, and the free plan does not expire.
