Explainers
The idea, in plain prose you can read.
Features
A course is a place, not a document.
Everything here exists because a plan you can't change, can't feed, and can't fall behind on is a plan you abandon in week two. This is what a course becomes once it exists.
27 ways to teach.
Count them.Every other tool teaches every topic the same way. BiliMind composes each lesson from all of this — and if a lesson comes back missing what its kind of knowledge needs, it's rejected and rebuilt.

What extraction actually means
Extraction is how much of the ground coffee the water dissolves on its way through. Too little and the shot is sharp and thin; too much and it turns ashy and dry.
Everything on the machine — grind, dose, time, temperature — is a lever on that one number.
Grounded in 1 of your materials
Cycling through all 27 — hover any pill to stop.
And it picks by what kind of thing you're learning.
Eleven kinds of knowledge, each demanding a different lesson. Tap around:
Walkthrough
Numbered steps you actually follow, one at a time.
Checklist
Keep it open while your hands are busy doing the thing.
Project + rubric
Do it for real, get graded against a clear bar.
Exam
For the stuff where getting it wrong isn’t an option.
A procedure gets steps and a checklist — never a wall of prose. If a lesson comes back missing what its kind needs, it’s rejected and rebuilt.
This is what a generated lesson actually looks like.
Not prose. A comparison built on the axes that separate the confusable things, key points, a drill — and a tutor docked beside the page that knows exactly which paragraph you're on.

Recognising sour, sweet, and bitter in a shot
1/6 · ComparisonEditMark complete
A shot can be harsh in two opposite ways. Sour and bitter both taste “off”, but they sit on opposite sides of the sweet window — and the fix for one is the opposite of the fix for the other.

- Sour (under-extracted) — a sharp, thin shot with no sweetness — you need more extraction.
- Balanced (sweet centre) — a shot you would happily drink twice — change nothing.
- Bitter (over-extracted) — an ashy, lingering finish — you need less extraction.
- Astringent — dry and rough alongside bitter — same fix as bitter.

Inside a lesson
Not a wall of text.
A lesson is assembled from the parts that suit what it is teaching — a proof gets a worked example, a fact gets flashcards, a skill gets a small project. You never get six of the same block in a row.
Worked examples
The idea, done once, step by step.
Questions
Ten kinds, picked to fit the lesson.
Flashcards
The facts worth carrying forward.
Diagrams
Drawn where a picture says it faster.
Small projects
Somewhere to actually use it.
It doesn't just show you.
It checks.
“Correct!” without checking anything is entertainment. Nine question types, each graded the way it deserves — here are three of them, exactly as they look in a lesson.

Woven into Lesson 2 and Lesson 5
Built for the four months after the excitement wears off.
Anyone can start a course. This is the machinery that gets you to the end of one.
Miss three days? The plan just… slides.
No red badges, no pile of guilt. Mark a day done or skipped and everything after it re-flows to fit the hours you actually have.
Re-flowed. Nothing lost.
Review lands right before you'd forget.
Finish a lesson and it quietly queues for review. Recall it easily, the gap widens. Fumble, it comes back sooner. Free forever, on every plan.
