A little about this place
Curiosity is enough.
You owe nothing.
Thought Gardens begins with a simple invitation: learn freely, and leave more able to explore. No account, payment, or return favor is needed.
These gardens carry the spirit of Education Engine and the dignity, choice, and transparency principles of IBOR v1.5.
What does “no telemetry in our code” mean?
The homepage and gardens contain no analytics, tracking pixels, advertising, external fonts, or profiling. They make no automatic requests to third-party services. The gardens keep only the current activity in memory and write no answers or progress to browser storage.
The games’ “Stop & clear” button clears their current activity. Your browser, extensions, and a website’s hosting provider operate separately; this code cannot promise to remove their history or prevent hosting access logs. Downloaded gardens can be used entirely offline.
For families, educators, and fellow makers
Questions keep generating within the chosen number range. Learners may select or type answers, explore a hint, reveal a worked example, and change level at any time. There is no learner profile or live AI service. AI assistance was used in making these pages.
Each original garden includes its MIT license in the source. Freely use, copy, adapt, and share under those terms. The review packages include Markdown guides, test results, and integrity manifests.
On a phone or tablet, a file previewer may not run the activity. Open the saved HTML in a browser that supports local files, or use the garden here on the site.
