One messy source in.
One structured roadmap out.
A textbook chapter, a lecture, a deck, an article — Ritsu reads it all and builds your roadmap: bite-size Points of Knowledge you can conquer one by one, each small win setting up the next — until the whole subject is yours.
The core move
Drop it in. Watch it become a path.
One continuous flow — a wall of pages in, a walkable path out.
- Step 1
Drop in anything — a PDF, a lecture, an article.
- Step 2
Ritsu reads every page and finds the ideas that matter.
- Step 3
Then builds your roadmap — units of atomic points, each small enough to win.
- Step 4
Every point carries its own check — so you never move on blind.
One wall of pages. One path you can actually walk.
The gap
A source is written to be read, not to be learned.
A textbook chapter, a lecture, a paper — they're built to be presented, in the author's order, at the author's pace. Open one and you hit the same three problems every time:
A source is a wall. You need a path.
One point of knowledge
Small enough to conquer. Complete enough to build on.
Every Point of Knowledge is one building block of the subject: a single idea explained simply, the usual trip-up named before you fall for it, the “aha” that makes it click — and a quick check to lock it in. Win this point, and the next one stands on it. That's how a whole subject gets built: one small victory at a time.
- factJuly 14, 1789 — a Paris crowd stormed the Bastille fortress.
- factIt held just seven prisoners — the crowd came for the gunpowder.
- contextParis was already primed: bread prices, troops massing, a sacked minister.
“It was about freeing prisoners.” It wasn't — the fortress was nearly empty. Its fall mattered as a symbol: royal power could break.
The Bastille mattered for what it meant, not what it held — symbols can topple states.
Why did storming a nearly-empty fortress shake the monarchy?
Open the point and Ritsu writes the lecture on the spot, from your source — built around your material, not a generic summary.
Finish it
A chapter stops being a blur. It becomes something you can finish.
No more wondering how much is left. Each point you finish lights up on the path; you always know exactly where you are and what's next — so a 40-page source turns from an intimidating wall into a short list you can actually get to the end of.
Point × commands
Stand on any point, and the whole command box is live.
A point isn't just something to read. The points are the map. The commands are how you move across it. See all the learning commands
Questions
What people ask before their first path.
A PDF, slides, a YouTube lecture, a web article, or your own notes — Ritsu extracts a path from any of them.
