Smart note-taking for your lectures

DAFi is an AI note-taking app built for university lectures. You record the class (or import what you already have), and DAFi generates a structured note: a course plan, a summary, the key takeaways and the full course written out. You stay focused on understanding the professor instead of racing to copy the slides.

How it works

1. Pick a source. Start a recording, attach files, add photos or paste a YouTube link. On a computer, use the web app; on the go, use the app on iPhone or iPad.
2. Record the lecture. You can pause and resume. On iPhone, recording keeps going in the background, even with the screen locked, and the audio is uploaded in small chunks as you go. If a call interrupts the mic or the app closes unexpectedly, DAFi offers to resume the recording or to generate the note from what was saved.
3. Add your own thoughts. While recording, open the "Take notes" panel and type what matters to you: a question, an example the professor insisted on, a "this will be on the exam". Your notes are added to the lecture transcript and used when the note is generated.
4. Get your note. DAFi reads everything, extracts the key concepts and structures the note into four parts: Course plan, Summary, Key takeaways and Full course.

What you can turn into notes

• Live lectures, recorded on your phone, tablet or computer.
• Files: PDF, Word, PowerPoint, images, audio and video. On the web you can drop up to 20 files at once.
• Photos of slides or whiteboards, taken with the in-app camera or picked from your library on iPhone and iPad.
• YouTube videos, from a link (see video to notes).

Notes are generated in French or English, depending on the language set in your profile.

Who it's for

Take Léa, a law student with three-hour lectures twice a week. She used to leave class with half-finished sentences and a sore wrist. Now she records, types two or three lines when the professor mentions a key ruling, and gets a full note she can review the same evening.

Or Karim, in first-year biology, who receives an 80-slide deck before every class. He imports the PDF, records the lecture, then adds the recording to the same note. The slides and what the professor actually said end up in one place.

Build on a note over time

A note isn't frozen once it's generated. With Sources, you can add documents, photos, audio or another recording to an existing note, and DAFi regenerates it with the new material. If you took several notes on the same chapter, Merge notes combines them into one; the originals go to the trash and stay recoverable for 7 days.

When you're ready to share, export the note as a PDF or send a share link to your study group.

Tips for better notes

• Place your phone close to the professor, or at least away from the chatty row.
• Import the slides before or after class: the note is richer when it combines what was shown and what was said.
• Use the "Take notes" panel for context only you have ("the prof said to skip section 4").
• Assign each note to a subject so you can organize your courses and track progress later.

Frequently asked questions

Can I use DAFi on my phone, tablet and computer?

Yes. The app runs on iPhone and iPad, and the web app works on a computer. Your notes are the same everywhere.

What happens if my recording gets interrupted?

The audio is saved in chunks during the recording. After an interruption, DAFi offers to resume; after an unexpected close, it offers to keep recording or to generate the note from what was captured.

Is there a transcript view?

DAFi focuses on the structured note rather than a raw transcript: the plan, summary, key takeaways and full course are what you study from.

What comes after the note?

From a note you can launch a quiz, get flashcards for the concepts you miss and follow a revision plan tailored to you.

Record your next lecture with DAFi, and spend the evening understanding it instead of rewriting it.
