You upload
A PDF, some slides, the recording of a lecture, or a transcript. Repeater pulls out the text, the audio, and the structure.
A tutor that starts from your material and comes back to your mistakes.
Repeater reads what you have to study, builds a plan, asks you questions, and explains again the point you missed. The next session starts there.

Four agents, one job each.
Each one hands the work to the next. The plan stays yours — you look it over before you start — and if a module breaks, it picks up from there.
01
The plan
It reads the document or the transcript, finds the topics, and puts them in order. The plan that comes out is yours to review and rewrite before you start.
02
The teaching
For each point it picks the form that carries it best: a short video, a map, flashcards, two cards side by side.
03
The check
It asks multiple-choice and open questions on the point you have just seen, compares your answers with the material, and explains again what went wrong.
04
The next session
It looks at the wrong answers, the steps you skipped, and the time each one took, and builds the next session from that.
From the file to the session.
Five steps. You do the first one, by handing over the material; the other four run on their own and stop wherever your answer is needed.
02
The plan
Out comes a plan of modules and steps, each with its own kind: explanation, quiz, summary. You can confirm it, change the modules, or have it done again before you start.
03
The teaching
For each step it picks a form: video with a voice, a map, flashcards, an animation, two cards side by side. The material opens right there.
04
The test
Quizzes and open questions. Answers go against the source material, and whatever went wrong is explained again. Then you choose: dig in, or move on.
05
The adjustment
Once the session ends, the system looks at where you struggled and prepares the next one around those points.
Every idea has its own form.
The system picks the form idea by idea, and looks at how the earlier times went.
Video with a voice
Short clips, voice and pictures together, built from the material and from the step at hand.
Maps
The shape of a whole topic, before you go into the detail.
Flashcards
A question and an answer, one at a time, when it helps to see what stuck.
Animations
Diagrams that move, for the processes and cycles where the movement is part of the meaning.
The next session comes out of this one.
At the end the system reads the trace back — answers, time on each step, repeats — and writes the following plan around whatever cost you the most. The more you use it, the closer it gets.
It remembers where you struggled
What you got wrong comes back, and every session starts from the one before.
It explains from another side
The topics that went badly come back first, in a different form and from a different angle.
You see the plan first
Every module says what it covers before the session starts. Rename it, move it, drop it, or have it done again: the loop runs on your version.
Where you need a path, rather than an answer.
When the material is long, the checking matters, and you have to be able to go back.
University study
A sixty-page chapter becomes one evening's plan, with the questions that measure what stuck.
Certifications
Long syllabuses split into modules you can test. The time goes where you get things wrong.
Internal training
Onboarding documents become guided sessions, with the checking already inside.
Studying on your own
You hand over a paper or a video, and the plan lays out its structure.
Questions
Why four agents rather than one big prompt?+
Each one has a narrow job: one returns the plan, another the teaching, another the verdict on your answer. So when something goes wrong, you can see where. A single prompt mixes the three, and on a long document it gets worse.
Can I change the plan before I start?+
Yes. The plan comes out in modules and steps, and every module can be renamed, moved, dropped, or done again before the session begins.
What happens if I get an answer wrong?+
You get a comment, and the part you missed is explained again. There is no grade and the session stays open: from there you choose to go back over it or move on.
How does it build the next session?+
It reads the trace of the earlier sessions back — wrong answers, repeats, time on each step, steps you skipped — and writes a new plan around the weak points, in forms other than the ones you have already seen.
What can I hand over?+
PDFs, slide decks, lecture videos, audio recordings, transcripts, and a written request on its own. Audio and video are transcribed and aligned before the plan starts.
Try Repeater on your next document.
You hand over the material, watch the plan take shape, and go through teaching and testing until the system has enough signal to aim the next session.
