Let your AI agent make your flashcards

Connect Claude to OxyLesson and ask it in plain words to search, add, edit or delete your cards, cloze cards included.

Start free

OxyLesson runs an MCP server, the standard way AI agents such as Claude reach other apps. Once you connect one, it works with your cards the way you would: it looks up what you already have, adds new cards, fixes a typo and removes a card you no longer need. It reaches only your cards, and only until you disconnect it.

  1. 01

    Search your cards

    Find cards by words in the front, back or notes, or by tags, newest first.

  2. 02

    Add cards in bulk

    Add up to 200 cards or cloze sentences in one go, with tags. Cards you already have are skipped.

  3. 03

    Edit and delete

    Fix a card or a whole cloze sentence, change its tags, or delete cards. A deleted card cannot be brought back.

Make flashcards from chapter 3 of a book

  1. 01

    Ask in plain words

    Give Claude the chapter and ask: “Make flashcards from chapter 3 and tag them chapter-3.”

  2. 02

    It checks what you have

    OxyLesson asks the agent to search your cards and list your tags first, so it reuses your tag names.

  3. 03

    The cards land in your library

    A card you already have is skipped. If one card is refused, none is added, so a retry never leaves half a chapter.

Create exam-ready flashcards from your notes in minutes Paste material from notes, PDF excerpts, docs, or course outlines and turn it into a strong first draft you can refine fast.

Keep reviews sustainable, even when your schedule is not OxyLesson helps you keep a manageable daily review rhythm instead of letting missed days explode into an impossible queue. Study diagrams and labeled visuals without rebuilding them by hand Upload visual material, hide the labels you want to test, and turn diagrams into reusable recall practice much faster than manual recreation. Know whether your study system is actually moving you forward Progress feels easier to sustain when you can see review consistency, streaks, and weak spots instead of guessing whether your routine is working.
