Built on the Ultralearning method

Start from the goal. Work back to what it needs.

Tell the coach what you want to be able to do. It maps the topics that goal depends on into a tree you can grow as deep as you need, with a note for every topic: what to memorise, what to understand, what to practise, and how to prove you know it.

How it works

Map it, then learn it, one topic at a time.

Most courses start from chapter one. You start from the thing you actually want, and only go as deep as that goal needs.

  1. 1

    Name a goal

    "Pass the AWS exam", "Speak conversational Spanish", "Build a neural net". The goal becomes the top of its own tree.

  2. 2

    Map what it needs

    The Mapper breaks it into only what's mandatory: branches, topics, and sub-topics under those. Expand just in time, where you're stuck or about to study.

  3. 3

    Learn and prove it

    The Professor teaches each topic's facts, concepts and procedures; the Examiner quizzes you and finds weak spots. Mark it learned and watch the branch fill up.

Already built

Everything you need to learn on purpose.

A note for every topic, split the way you learn.

Each topic separates what to memorise from what to understand and what to practise, so you always know what kind of work it needs.

  • Facts: atomic things to remember, one per card.
  • Concepts: ideas explained simply, as if you were teaching them.
  • Procedures: ordered steps to drill until they're automatic.
  • Self-test: one question that proves you know it.
  • Real math in LaTeX, drag to reorder, edit in place.

A team of AI coaches, each with one job.

They read your tree and edit it with you, and hand you to each other when your question belongs to someone else. Every change shows up as a link you can jump to.

  • Goal turns "I want to learn X" into a clear goal with a real test of done.
  • Mapper maps only what's mandatory, benchmarked against how the skill is normally learned.
  • Professor teaches with the techniques that fit the topic and you, and fills in notes.
  • Examiner writes exam questions, grades your answers and points out weak spots.
  • Librarian finds books, courses, videos and exercises, and checks every link before saving it.

Each goal keeps its own conversation and memory: your level, deadline, what confuses you. They draw when a picture helps (diagrams, charts, math graphs) and run code to check the math.

And the rest of what's in the box

Small things that make it stick.

A tree that never runs out of depth

Any topic can grow its own sub-topics, and those theirs. Collapse branches, pan and zoom, and jump around the board.

Mastery you can see

Mark topics not started, learning or learned. Branches and goals show progress over their whole subtree.

Exam mode

Answer the Examiner's questions on a topic and everything under it: recall, explain, apply. Answers are graded on understanding, not wording, with feedback on what was missing.

30 learning techniques

Retrieval practice, worked examples, Feynman, interleaving, shadowing and more, each with its evidence. Mark favourites and ones to avoid; the Professor picks from those.

Resources on every topic

The Librarian searches for the best material at your level, opens each page to check it's real and current, then saves it on the topic.

Math that looks like math

Write LaTeX inline or as display lines in any card, with a palette of symbols when you don't remember the syntax.

Pictures in your notes

Flowcharts, mind maps, timelines, data charts, function plots and simple sketches, drawn from text right inside a card.

Goals, grouped

Keep many goals at once and gather them into groups, like "Work", "Languages" or "Exam season". Each goal keeps its own coach conversation.

Feels like an app on your phone

Pinch the board, swipe the note sheet, study on the bus. No zooming, no fiddly layout.

On the roadmap

What's growing next.

Dashed cards on the board are topics that don't have a note yet. These don't have code yet. Waitlist members hear about them first.

Soon

Spaced-repetition review

Exam questions and facts come back on a schedule, right before you'd forget them, so learned stays learned.

Soon

Accounts and sync

Sign in and keep every tree, note and conversation with you across your laptop and phone.

Soon

Share and fork trees

Publish a goal's tree. Others copy it, make it theirs and grow it in their own direction.

Soon

Import your sources

Drop in a PDF, an article or a video and get a starter tree, with notes drawn from the material itself.

Waitlist

Join the waitlist.

We're still building it. Leave your email and we'll write to you when it's ready. Tell us what you want to learn: it helps us decide what to build first.

We'll only use it to tell you when it's ready. No spam.

You're on the list.

We'll email you when it's ready. Until then: think about the one thing you'd most like to be able to do in three months. That's your first goal.
