No coding needed — just your ideas and the right words. Poke at every animation below, and you'll walk into AI Builders Day already knowing the ropes.
“LLM” stands for Large Language Model — the “AI” you'll build with. Here's the whole idea in one picture.
An LLM is a super-smart autocomplete. Nobody typed in the answers — it learned patterns by reading a giant library of writing. It studied millions of sentences like:
…so now it's great at guessing what comes next:
It leans toward its best guess, but it could pick another — that's why it can be creative. Chain thousands of these guesses and it writes stories, answers questions, and builds apps.
An LLM answers by predicting the next word again and again. Watch it build a sentence from a prompt.
First the AI reads your whole prompt — every word gives it clues. Then it writes the answer one predicted word at a time.
Every new word is a fresh guess based on everything so far — like stacking LEGO bricks into a wall, one at a time.
Before the AI can read your words, it breaks them into little pieces called tokens. Try splitting some yourself.
Computers don't read whole words — they chop text into little pieces called tokens. On average a token is about 4 letters. Tap a phrase, or type your own:
Under the hood every token is really a number — tap “Show token IDs” to peek. The AI does all its thinking with those numbers, then turns them back into words for you.
Building costs credits — a bit of “fuel” for each request. See how clear prompts stretch them further.
Credits are like arcade tokens. Every time the AI builds or fixes something, it uses a few. You get a bucket for the day — spend them wisely and they go further.
Tip: clear, one-thing-at-a-time prompts cost fewer credits and work better.
A prompt is how you talk to the AI. Compare a vague prompt with a clear one, then try your own follow-ups.
A prompt is you telling the AI what you want. The best ones have three ingredients:
make a game where a cat catches falling pizza on a sunny park background and shows the score at the top

Made something awesome? Publishing puts it online so anyone can visit. Give it a try.
When your app works, you publish it. Lovable puts it on the internet and gives you a link (a URL) — send it to anyone and it opens on their phone. Try it:
Nothing is shared until you send the link. You decide who gets it.
Keep building and press Publish again — the same link shows your newest version.
