How it works
-
Describe it
Name the topic, the age or level, and the activity if you have one in mind: “a quiz about volcanoes for 11-year-olds”. Name no activity and PuzzleGPT suggests three that fit, then makes the one you pick.
-
It makes the activity
PuzzleGPT picks the activity type, writes the content and saves it in your account. You get a link to play it and a link to open it in the builder.
-
Ask for changes
Reply with what to change: “harder”, “more questions”, “call it Planets”, “add a 5-minute timer”. PuzzleGPT changes the activity it made, and “Restore the version before this change” brings the old one back. Ask for another kind, like “as a crossword”, and it makes a new one.
-
Bring your own picture or worksheet
With a free account, attach or drop in a photo to turn it into a jigsaw or sliding puzzle, or a worksheet (a PDF, a photo of the page or a Word file) to turn it into a quiz or another activity. No picture at hand? PuzzleGPT draws one for your jigsaw.
Inside the builder
Already building? The AI assistant fills one part at a time.
Once you are signed in, the builders also have an AI assistant next to their content fields. Give it a theme, two languages, a worksheet or a picture description, and it fills the fields you would have typed, on the same credits as PuzzleGPT.
Worked examples, one per mode: the brief that was given and what came back.
Builder AI
Language pairs, no typing
Pick a theme and two languages. The AI assistant writes matching answer pairs and feeds them into a language puzzle.

- The weather

Answers AI
General-knowledge sets from one line of brief
Name the theme and pick a difficulty level; get answers with clues written at a readable level, not an encyclopedia dump.
“Rivers of Europe, primary school level”
Quiz AI
Multiple choice, wrong answers and all
Distractors that are plausible rather than silly — the slow part of writing a quiz, drafted for you to prune.
“Ten questions on the Roman Republic”
Image AI
Artwork for any image field
Describe what you need and drop it into memory cards, jigsaws, sliding puzzles or hidden-object scenes.
“Flat-colour cartoon rain cloud, no text”
Credits
Try it without an account, then use AI credits.
The models run on outside providers, so making activities isn't unlimited. Each activity PuzzleGPT makes uses a credit, and so does each change to its content. Changing only its settings or its name is free, and so is anything that doesn't end in an activity: its suggestions, a help answer or an attempt that fails. Each generation in the builder modes on this page is a credit too.
Without an account 3 tries
A new free account 3 credits, once
Every plan, each month 5–30 credits
One activity from PuzzleGPT 1 credit
Editing and reusing what it made free

Where it shows up
Here, on your dashboard and in the builders
The box at the top of this page, on the homepage and on your dashboard starts a chat with PuzzleGPT, and on a larger screen the PuzzleGPT button in the corner opens your earlier chats. In the builder, the AI assistant writes answers, clues and quiz questions for these activities:

Already chatting with Claude or ChatGPT? Ask there.
PuzzleGPT works here on Puzzel.org. The Puzzel.org connector works from your own assistant: ask it for a crossword or a quiz in the chat, and it lands in your account with a link your class can open. It uses no credits and needs no paid plan.
What teachers ask about the AI
Who owns what the AI writes?
You do. The content is generated for your activity, and you can edit or delete any part of it before sharing.
Is it ever wrong?
Occasionally, like any language model. What it makes is saved in your account and reaches your class only when you share its link, so open it in the builder and check it first.
Does it work in my language?
Yes. PuzzleGPT writes in the language of your request, or in another one when you ask for it (“in Spanish”) or when the activity practises a language. Puzzel.org itself speaks 23 languages, and in the builder the assistant translates between language pairs, right-to-left scripts included.
What happens to a worksheet I attach?
It is used only to write your activity, never to train models or to show to other accounts. In PuzzleGPT the worksheet itself is not kept: it reads the text, is asked to leave pupils' names out, and saves only the file's name and type with your chat.
Do I need an account?
Not to try it: you get 3 tries without one. A free account adds 3 AI credits, once, and keeps the activities you made. More credits come with a plan.
What won't it do?
PuzzleGPT only makes activities: it won't chat, answer questions or write essays. A few settings, such as links and the buttons that reveal answers, stay in the builder; it tells you when it can't do something. Without an account it still draws the picture for a jigsaw or sliding puzzle; pictures on the cards and attached files need a free account.
Can it change the settings too?
Yes. Ask for more puzzle pieces, shuffled questions, stricter answer checking or a timer and it changes them, and changing settings costs no credit. A few, like the timer, need a paid plan, and it tells you so. Settings that decide who can open the activity or what is kept about players, such as making it public or asking players for their name, wait until you press Confirm.

Tell PuzzleGPT what your class should practise and get an activity to play and edit. Your first 3 tries need no account.
