About Clever Quest Lab

Clever Quest Lab is a free educational website with two parts: study materials in Slovak for school students in Slovakia, and free online tools, games, simulations and slides in English for everyone.

The website is run by Simpli, a private individual based in Slovakia.

What you will find here

School (Škola) — study materials in Slovak for students at primary and secondary schools in Slovakia: study texts, short summaries, interactive tests and visual materials such as infographics, diagrams and mind maps, organised by subject, grade and topic.
Tools — free online tools that work in your browser, for example a unit converter, a word counter and a voice dictation tool.
Games — simple games you can play in your browser, such as a memory game.
Labs — interactive simulations and visual explainers: play with physics, algorithms and AI in your browser.
Slides — short presentations you can view in your browser.

Who it is for

The school section is written for students at Slovak primary and secondary schools (základná a stredná škola), and teachers and parents can use it too. The tools, games, simulations and slides are in English and are meant for anyone, anywhere in the world.

How the materials are made

The materials are prepared by the operator of the website, some of them with the help of artificial intelligence tools. They are meant as a study aid: they do not replace your textbook, your lessons or your teacher's instructions, and they may contain mistakes. If you notice one, please let us know so it can be corrected.

Everything on Clever Quest Lab is free. There is no registration, there are no user accounts and there are no forms to fill in. Most tools work entirely in your browser, so what you type into them stays on your device (the voice dictation tool is an exception, explained in the Privacy Policy).

How the website is funded

The website is funded by advertising: it uses or may use ads from Google AdSense. How advertising, cookies and your consent work is explained in the Privacy Policy.
