a little program learning to read

Watch it learn its letters — then teach it yourself.

It learns the way a curious child might: by seeing a shape, hearing a sound, and noticing they belong together.

what is this, really?

A gentle, honest little machine

This is a tiny computer program — not a person, not magic — that is learning the alphabet one letter at a time. You can watch it learn, and you can teach it.

Show it the letter A and it will say the sound and draw the shape back to you. Play it a sound and it will draw the letter it heard. Draw your own letter with your finger or mouse and watch it try to guess — and sometimes get it wrong, which is a completely normal part of learning.

It runs entirely in your web browser. There is nothing to install, no account to make, and nothing about you is collected. It is free and it is yours to explore.

try it in three steps

Three little things to try

STEP 1
👀

Show it a letter

Press A. The program looks at the shape, then says the sound and draws the letter it recognises.

STEP 2
👂

Play it a sound

Press a sound button. It listens, then makes a picture of the letter it heard — from memory.

STEP 3
✏️

Draw your own

Draw a letter yourself and press Test it. Watch it guess. When it misses, ask your child why — that is the fun part.

three alphabets, together

It learns English and Hindi at the same time

Every letter is taught in three ways at once — the Latin shape A, its English sound, and the Hindi (Devanagari) shape .

It doesn't keep them in separate boxes. It notices that a shape and a sound keep appearing together, and links them — the same simple idea a child uses when they learn that the squiggle “A” and the sound “ah” go hand in hand. Because it learns them side by side, if you play it a sound it might draw you the English letter or the Hindi one — it knows both.

PLAYGROUND
🎈

The simplest one to try first

Press a letter, hear its sound, watch it draw. Or draw your own letter and see if the program can guess it. Best for kids and first-time visitors.

BEING
🌱

Watch a little "being" teach itself

A small program with its own eyes, ears, hand, and voice. It teaches itself the alphabet in a few seconds, then you can show it letters, teach it your own voice, and even give it a bigger eye to see with. Nothing about you is uploaded.

EYE LAB
🔬

Draw a letter — three eyes learn it

Draw any letter and three eyes (tiny, medium, big) each look at it, remember it, and draw back what they remember. A hands-on way to see why eye size matters for how well you can see.

OBSERVATORY
📖

Look under the hood

For the curious: a plain-English tour of how a shape and a sound become the same kind of "signal" inside the program, and exactly what it can and cannot do.

for parents & teachers

A calm, screen-time-that-teaches kind of thing

No rush, no scores, no “levels”. Just a quiet little machine you and a child can poke at together and talk about.

Questions to ask a child

“What sound does A make? Can you draw it?”
“The computer drew that — does it look right to you?”
“Why do you think it got confused by your letter?”

Getting it wrong is a doorway, not a dead end. Every miss is a chance to notice how careful reading really is.

A lovely honesty lesson

The program does not understand letters the way we do. It notices patterns — which shapes and sounds appear together — and counts them. That's it.

This makes a wonderful, true conversation: computers are very good at spotting patterns, and they don't “know” things the way you do. A gentle, age-appropriate first look at what today's “AI” actually is — and isn't.

A note on honesty

We try to be careful, not clever. This is a learning demonstration, made with a simple, old-fashioned kind of maths (counting, not the giant “neural networks” behind most chatbots). We tell you plainly what it can and cannot do.

It is not a real child, it does not see or hear or understand, and it is not “artificial intelligence” in the movie sense. What it is: a small, transparent program that learns letters by noticing patterns — and every claim we make about it is something you can check yourself.

for the curious

Want to look under the hood?

If you're the technical sort, there's more to see. The Observatory shows how a shape and a sound become the same kind of "signal" inside the program. The Being page shows the same little program doing much more (teaching itself, hearing your voice, drawing with different-sized eyes). The Eye Lab lets you compare a tiny eye and a big eye side by side. And the whole thing is built to be pressure-tested — you can try to break it and see where its honest limits are.
