Turn the articles you forget into knowledge you keep

Paste any article. Ritsu pulls out what it actually claimed, quizzes you on it while you still remember reading it, and brings it back days later — right before it would have evaporated.

A 20-second product loop: a document becomes a step-by-step learning path in Ritsu.

The illusion nothing corrects

You read thirty articles a week. You remember one.

Read-it-later is where articles go to die, and a tab you never close is not a plan.

You have forty tabs open. You have a read-it-later app with three hundred articles in it. Last month you read something genuinely good, and today you could not reconstruct a single specific claim from it.

This isn't a memory problem. It's a method problem. You consumed it once, passively, and were never once made to produce it back. Nothing that goes in that way stays. And here is the part that makes an article worse than a chapter: a chapter has an exam waiting for it. An article has nothing. Nobody will ever ask you about that blog post — so you are never told you lost it. You just quietly go on believing you know it.

There's only one way out: stop collecting. Start being asked.

The workflow

From a tab you'd have closed to a thing you actually know.

01

Paste the URL

No file. No download. No copy-pasting into a chat box. Blog, docs, news, a Substack post — if it's public, paste it.

02

What it actually claimed

/concepts pulls out the ideas the piece was really making — curated, ordered foundational to advanced. Not a summary you'd skim. The list you'd be quizzed on.

03

Get asked, right now

/quiz while you still remember reading it. This is the thirty seconds that changes everything — and the reason nobody has ever done this before: building a card for a blog post takes longer than reading it. Not any more.

04

Say it back

/askme — explain it in your own words. That's where “I read that” turns out to mean “I recognised the words.”

05

One click puts it on the curve

Add it to review and Ritsu brings it back on Thursday — right before Tuesday's article would have evaporated. Pocket stores it. A highlighter marks it. Neither knows when you'll forget.

06

A week of reading, with a shape

Concepts scored, dim ones named. A reading habit turns into something with a shape.

Pedagogy, packaged

Every command packs a proven learning method.

Pick any concept the article made. Six commands take it from “I read that somewhere” to “I can write it from memory” — each one asking more of you than the last.

The habit loop
/explain01

Understand

The core idea first, then the layers — built from the piece you just read.

/quiz02

Recall

Retrieval practice: the most proven way to make it stick. Pull it back out, cold.

/flashcard03

Drill

The parts that have to be automatic, turned into cards you'll actually run.

/askme04

Explain back

The Feynman test. Say it in your own words — that's where the gaps show.

/exercise05

Apply

A real problem on the real concept. Knowing it and using it aren't the same.

/write06

Create

Write it out in full. The highest bar there is: if you can write it, it's yours.

That's Bloom's taxonomy, climbed one command at a time. And the science isn't a slogan — it's a flag on the command:

/quiz --bloom="auto"

40+ commands, all built like this.

Knowledge Map

You always know exactly where you stand.

A bookmark folder is a list of things you meant to know. Ritsu scores every concept as you work — the dim ones are exactly what you haven't got yet.

01

Every concept, scored.

Not one vague % for the article — a mastery score per concept.

02

Dim = what will bite you.

The concepts you haven't got yet, named. That's the list nobody else gives you.

03

The whole piece, one screen.

Not a highlight reel — a map of what the article actually claimed.

The forgetting curve

Everything else stores the article. Nothing else knows when you'll forget it.

You forget most of what you read within days — Ebbinghaus measured it in 1885. A read-it-later app stores the article. A highlighter marks it. Neither has any theory of when it fades. Ritsu brings the concept back right before it does.

One click puts it on the curve. Ritsu brings it back right before you'd forget.

When you're stuck

The moments you actually get stuck — and what to type.

That's recognition, not knowledge — and reading is where the two look most alike. /askme: explain it back in your own words and Ritsu names exactly where it broke.
