How it works

From the professor’s material to the student’s exam.

One upload carries the whole loop — the lecture, the live class, tonight’s revision, and the gaps you need to reteach.

01

Upload material

Your PDF or PPTX, kept exactly as you wrote it. We add quizzes and flashcards on top — no rebuild.

02

Teach live

Present from your deck. Launch a check-in question at the right slide and watch answers land in real time.

03

Students study

After class each student gets their weak concepts, spaced-repetition cards, and a tutor grounded in your material.

04

Inspect the gaps

Class mastery shows which concepts landed and who needs another pass — before the exam, not after.

The after-class tutor

Answers that sound like the professor, not a generic search engine.

Every answer is retrieved from the material you uploaded and cited back to the slide it came from. Ask something you never covered and it says so, instead of inventing an answer.

  • Grounded in your closed corpus — nothing else
  • Cites the slide behind every claim
  • Refuses politely when it isn’t in your material
  • You can read every transcript, and switch it off

Why does the electron transport chain need oxygen?
Oxygen is the final electron acceptor — without it the chain backs up and ATP synthesis stops.Source: your slide 24 — “Stage 3: Electron Transport Chain”
What’s on the midterm?
I don’t see that in your professor’s materials, so I won’t guess.

Designed for the professor. Loved by the student.

For professors

Teach the same class. Support every learner differently.

  • Keep your deck — we add, never rebuild
  • One click to launch a question mid-slide
  • See which concepts landed, per student
  • No new prep the night before
For students

Keep learning after the room empties.

  • Your weak concepts, queued for tonight
  • Spaced-repetition cards from the real lecture
  • A tutor that only uses your professor’s material
  • Practice that actually predicts the exam
For universities
