About this app

YDABlocks is not an assistant you ask things. It is four blocks you assemble into a small language model — and then watch reason, one step at a time.

Write a sentence with a blank in it. Run it, and see the machine work: one block reads the sentence and maps every word, one decides which word matters most, one works out the relationship, and one scores the
candidates and picks an answer. Nothing is hidden. Every answer traces back to the step that produced it.

Then you teach it.

WHAT YOU DO

Builder — Tap words from a bank of 6,000+ across dozens of categories, or type your own, and leave a blank where the answer goes. Run it and watch all four blocks work.

Training Pairs — When the answer isn't what you wanted, correct it. That correction is saved, and from then on your build uses it. This is the real lesson: a model is only as good as what it was shown.

Fine-Tune — Decide how much your build leans on what you taught it versus what it works out on its own. Pick a grade band so the vocabulary fits your reader.

Product — Turn all of it into a chat you can talk to and share.

Chat — Talk to the thing you built. It answers from your training pairs and the relationships it can work out. Ask it the same question twice and you get the same answer, because it is deterministic — which
is the whole point. You can always trace why it said what it said.

Richard — Your YDABlocks partner. Ask him about a result you didn't expect, a block you're not sure about, or what to try next.

WHO IT IS FOR

Anyone who wants to understand how AI actually works instead of being told to trust it. Learners, teachers, parents, and curious people who would rather see the machinery than the magic.

Free to use, with a word bank of thousands of words and no upgrade needed to build. Optional subscriptions unlock more.

What’s new

Try the full Builder without an account.

New launch screen that loads your accessibility settings before the first frame.

Fixes: saving a Build no longer reports success when it failed, the keyboard no longer covers what you type, and slow connections time out instead of hanging.
