We build edtech around what
you know.

Simulations, lessons
and expert-led tools.

Education is our home ground. We also take on other small AI builds, with clear checks and a person in charge.

What we do

Three things in everything we build.

SampleA student’s answer

A ball is dropped from 20 m. How fast is it going at the ground?

  1. v² = 2gh
  2. v² = 2 × 9.8 × 20
  3. v = 19.8 m/s

The teacher’s rules

  • Uses v² = 2ghline 1
  • Gives a unitline 3

Calculated

√(2 × 9.8 × 20)
= 19.80

1 + 1 + 1 = 3

Fastest way to orbit near the ground?

Physics notes Orbits Sample

  1. Newton imagined a cannon on a very high mountain.
  2. A slow cannonball falls to the ground near the mountain.
  3. A faster cannonball lands further away.
  4. At about 7.9 km/s, the Earth curves away as fast as the ball falls.
  5. The ball keeps falling but never lands. This is an orbit.
  6. Gravity provides the centripetal force, so v = √(GM/r).
  7. Ignore air resistance throughout.

Your rules set the mark.

SampleA ball is dropped from rest from 20 m. Find its speed at the ground. Take g = 9.8 m/s².

  1. v² = 2gh+1
  2. v² = 2 × 9.8 × 20 = 392+1
  3. v = 19.8+1−1 no unit
