Your course, set as a book worth studying.
Chameleon reads your PDFs, slides and notes, takes on the discipline they belong to, and sets them into one cited book. You get a tutorial written to be read, flashcards that name their source pages, quizzes marked like an exam, and figures the server computes from the real mathematics of the subject. A spaced-repetition schedule then shows you what to review each day.
New study planMost tools hand back a summary and leave the studying to you. Chameleon reads your material closely, the way a careful tutor would, then rebuilds it into something you can study from. It stays grounded in your own sources, draws the subject correctly, and schedules your review so the material holds through to the exam.
From files to a finished book
Bring the whole module
Add your PDFs, slide decks and notes together, up to a scanned book of several hundred pages. Chameleon reads every chapter, figure and citation, then merges them into one clean structure.
It takes on your subject
It identifies the discipline and works in the persona of a specialist in it, applying the grading standards and the specific misconceptions examiners in your field look for.
Study the book it sets
Read the cited tutorial, drill flashcards on a spaced-repetition schedule, and sit an exam-grade quiz that marks your written answers in the standards of your subject.
Everything a subject needs
A specialist in your field
Chameleon identifies the discipline and adopts the persona of a specialist in it, applying the standards and evaluation criteria that field uses, whether law, finance or chemistry.
Set like a book
Concepts, the connections between them, the misconceptions worth naming, and a closing synthesis. A tutorial meant to be read from start to finish.
Every claim cites its page
The material is built only from your files. Each card and quiz question points to the source page it came from, and anything the model cannot ground in your sources is dropped before you see it.
The subject, drawn correctly
Forty-seven figure types whose result the server computes rather than sketches: a Riemann sum that sums, a titration at the true pKa, a circuit solved by Ohm's law.
What is due today
An FSRS schedule models the memory of every card and estimates the day you will forget it, so each morning shows the smallest set that keeps the syllabus fresh.
Exam-grade, and graded
Multiple-choice and written questions, marked to the standards of your subject, with a score and specific feedback on what to correct.
Readiness, stated honestly
Mastery, a forgetting forecast, and a calibration panel that measures how far the model's predictions run from your actual recall, week by week. Every number is computed, never generated.
A short daily set
Mixed questions drawn across your plans, with progress, levels and a record of everything you have reviewed.
Every claim traces to your page.
No floating facts, no confident guesses. Every flashcard, tutorial claim and quiz question points to the exact page in your sources, and anything the model cannot ground gets dropped before you ever see it. When something surprises you, the original is one click away.
One idea, elasticity, connects the whole week: who really pays a tax, why a price cap leads to shortages, and how a good harvest can still leave farmers worse off.
It shows you what is due today.
A modern spaced-repetition engine, FSRS-5, models the memory of every card you have seen and estimates the day you are likely to forget it. Each morning Chameleon shows the smallest set of cards that keeps the whole syllabus fresh, and counts down to your exam date.
Comfortable to read, by default.
A full reading-accessibility suite is built in. Set it once, and it follows you through every tutorial, card and quiz.
What it draws, what it measures
Chameleon draws the subject, and every figure is computed on the server to be correct rather than sketched to look right. Here is a sample of what a chapter can hold, alongside the analytics built from your own study record.
Supply & demand
The equilibrium is solved from the curve equations, with surpluses and price controls shaded from the same figures.
Read how it actually works
The claims on this page each have a longer story behind them. Three short reads, written the way the product is built: specifically, and without exaggeration.
How Chameleon teaches
From atomised source pages to concept cards, connection cards, and a reader that adapts to your review record.
Computed, not sketched
Why every diagram is calculated on the server from the subject's real mathematics, and what the 47 figure types cover.
Numbers you can check
The memory model, the forgetting forecast, calibration, and what the readiness figure is honestly made of.
Before you upload
PDFs, Word documents and PowerPoint slides. A textbook, the lecture deck and your own notes can all live in one study plan, and Chameleon combines them into a single chapter structure.

Upload a course, and your first chapter comes back ready to read: a cited tutorial, a deck of flashcards and an exam-grade quiz. Free to start, and your files stay yours.
