Make everything you learn finally click.
obbler turns the videos, PDFs, photos and links you study from into notes, flashcards and quizzes, then shows how much you really understand.
START WITH ANYTHING
Add a PDF, photos, a video or article link, or write your own notes. obbler makes a clear note from it in about a minute.
ASK, AND IT MAKES THINGS
Chat with your material. Answers come from what you added, with the passage they are based on. Ask in plain words to add to a note, make flashcards from it or quiz you on the weak ideas.
PRACTICE THE WAY IT STICKS
- Flashcards you answer from memory: Knew it or Didn't know. Cards come back just before you would forget them.
- Quizzes made from your own material.
- Highlights for the passages you want to keep.
PROGRESS YOU CAN TRUST
Progress counts only what your quiz and flashcard answers prove, not what you say you know. See it per subject on Home, and idea by idea inside each material.
obbler Pro is a monthly or yearly auto-renewing subscription with a 7-day free trial. Payment is charged to your Apple ID account at confirmation of purchase and renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID settings.
