How · Vibe coding + block coding
  • AI skills + coding, taught together
  • Understand the logic and structure
  • Blocks, flowcharts & code connected
  • Safe, education-focused AI

From AI-made results to real understanding

STEP 1

Ask in words

Describe what you want to make, and AI builds a block program.

STEP 2

Check the result

Look at the blocks and the running result together to see how it works.

STEP 3

Improve

Find what to fix, edit the blocks, and finish your piece.

Two AI tutors by your side

Whether building or learning, Keo is with you.

Builder AI

Say what you want and Keo builds and edits the blocks — confirming your intent first, then explaining how it was assembled.

Let me move with the arrow keys, and say 'Ouch!' when I hit a wall
Here's what I understood! The arrow keys move Keo in that direction, and when it hits a wall it says 'Ouch!'

Keo the Teacher character

Keo the Teacher

Tutor AI

Ask anything and Keo explains, brainstorming new ideas with you. Level-matched hints build the skill of thinking for yourself.

What is a loop block?
It runs the same action over and over. Can you find the part of your code that keeps repeating?
Ask me anything!

  • How do I get started?

    Submit an adoption inquiry and we'll proceed with a contract. Vibe Block is available as a subscription.

  • If AI builds everything, do students still learn?

    Vibe Block is designed around a three-step structure: ask in words, check the result, improve. Opening, reading, and editing the AI-built blocks is the core of the learning — and Keo the Teacher only gives hints and ideas, never finished answers.

  • What can students make?

    Anything from simple motions to games. On top of the built-in assets, students can generate their own objects for richer creative work.
