The tutor that asks

How much of what you know is solid ground?

Socrat finds what's hollow, then helps you build it, by thinking it through yourself.

Scroll, and the clouds part

Most of what we know is cloud.

Only a few things rise all the way through.

Truly understood
Known by name

How understanding works

Understanding is built in layers.

Every idea rests on the ones beneath it.

Socrat looks underneath.

Tests check the surface. Socrat checks every layer below it.

A missing layer is a jump.

It looks solid from above. Socrat finds what's missing and builds it, bottom up.

Other AI gives you the answer. Socrat gives you the understanding.

A typical AI

The slope is 3. Here's the formula.

Fast. Correct. Forgotten.

Socrat

The plant was 4 cm, then 10 cm two weeks later. What happened each week?

You work it out. It stays.

Stuck? Each step gets smaller.

None of them is the answer. You reach that yourself.

It speaks the language of what you love.

If you play tennis, slope might start like this:

“You're up 5–2, but she's won the last four points. Who's really winning?”
Ahead = heightScoring faster = slope
You: aheadHer: scoring fasterPoints played
Then you say it in plain math, no tennis words.

It remembers how you think.

  • What you love
