NipsoleBeta

Anything explained, drawn by hand.

Name a topic and have it mapped, taught at a whiteboard, or worked through a step at a time. Everything is drawn as it is explained, and nothing stops at the label: click any edge of a map and that part opens up too. There is no bottom — it keeps going as long as you keep asking.

How a cache stays fast

Three ways to be shown.

Same box, same board, same hand. Which one you want depends on whether you are getting your bearings, being taught, or stuck on a particular problem.

Mindmap

The shape of a subject: the central idea, what it really divides into, and the specifics under each. Click any end and it grows there.

Lesson

A whiteboard that talks. It draws while it explains, each thing landing on the word that introduces it, and you can interrupt to ask.

Math tutor

A problem worked through a step at a time, with the reasoning written out beside the working rather than an answer handed over.

Or have it taught to you.

The whiteboard draws while it explains, each thing appearing on the word that introduces it. Here it is drawing, with the narration written underneath.

Why your CPU has a cache
PROCESSOR 0.3 ns per step

Your processor does something every third of a nanosecond.

It goes down, not wide
A leaf is not the end of the map — it is the part nobody has asked about yet. Click it and its own branches get written, where it stands.
It explains at the edges
Four levels down you have stopped scanning a structure and started reading about one thing. So that is where the sentences are, not on the labels near the middle.
It waits for you
A lesson holds on a full board long enough to read it, and stops when you type a question — answered on its own board, then back to where you were.
It looks drawn
Hand-drawn boards, one colour per limb, with a symbol sketched to order for each branch. A whiteboard someone worked at, not a chart.

One plan. All of it.

There is one product here and everybody gets the whole thing. The only decision is how long you are committing for.

Beta

Early, and honest about it.

nipsol works — the maps, the lessons and the tutor are all real and all yours to keep. It is also new: boards change as we improve them, and the prices are not carved anywhere yet. Nothing you make is thrown away when something changes.

If something breaks, or draws the wrong thing, or explains it badly — tell us. At this size a message actually changes the product.

Raising

We are raising, and talking to people.

We are raising a round to keep building this — a teacher that draws, explains and keeps going as far down as you want to follow it. If you invest in things at this stage, we would rather talk early than pitch late.

The fastest way to understand it is to use it: make a map, open a branch, and see how far it goes.
