IsThatStillTrue.com is a live educational website that helps people check whether facts they learned at school are now outdated, changed, or simply wrong.

What does IsThatStillTrue.com actually do?

The main idea behind IsThatStillTrue.com is simple: knowledge changes, but the facts stored in our heads often do not.

The site asks users to choose a country and a graduation year, then it tries to show school facts that may no longer match current knowledge.

This approach makes the site different from a normal fact-checking page because it starts with what a person may remember from school instead of starting with a news claim.

It also offers a “School Mode,” which appears designed around curriculum-specific memories rather than random facts.

That is a smart concept because a person who finished school in 1985 may have learned a very different version of science, geography, or history from someone who graduated in 2020.

What can you do on the website?

The main homepage includes several ways to explore changing knowledge.

Users can select a country and school year, ask an AI fact-checking bot a question, take a ten-question quiz, or use a random “Surprise me” option.

The site also has a “Sounds Fake, But It’s True” section that presents surprising statements before revealing whether they are real.

Examples shown on the site include claims about sharks being older than trees, Venus having a day longer than its year, octopuses having three hearts, and bananas being berries.

This makes the experience feel more like a learning game than a reference encyclopedia.

That choice is useful because most people will not visit a website just to read corrections to old textbooks, but they may stay to test what they think they know.

Is IsThatStillTrue.com a real and active website?

Yes, the site is currently reachable and its main content was accessible when checked in August 2026.

The homepage includes working sections for country-based exploration, quizzes, an AI fact checker, educational resources, privacy information, terms, an imprint, and donations.

The footer credits “Klexgetier - Maximilian Leistner” and displays a 2024 copyright notice.

A copyright date alone does not tell us when the site's information was last revised, so it should not be treated as proof that the database stopped changing in 2024.

I also found very little independent discussion of the domain in normal web search results.

That means the site has a much smaller public footprint than large fact-checking organizations or major educational platforms.

Can you trust the facts on IsThatStillTrue.com?

The site says its purpose is to help people understand how facts evolve and includes an FAQ specifically addressing whether its information is accurate and verified.

It also links users toward well-known academic and educational organizations such as MIT OpenCourseWare, NASA, the National Science Foundation, the Library of Congress, Yale, Harvard, Khan Academy, Oxford Academic, Cambridge University Press, and the Smithsonian Learning Lab.

Those links are a positive sign because they encourage users to go beyond the site's own explanations.

However, linking to trusted institutions does not automatically mean every individual claim on IsThatStillTrue.com has been checked by those institutions.

For important questions, the best use of the site is as a starting point rather than the final source.

If a result affects school work, medical choices, legal decisions, money, or another serious issue, users should open the original scientific paper, government source, university publication, or other primary evidence.

What is the strongest idea behind the site?

The strongest idea is not fact checking itself.

It is the idea that a fact can feel completely certain simply because we learned it when we were young.

School knowledge often stays in memory for decades, while science, maps, classifications, historical interpretations, and measurements keep changing.

IsThatStillTrue.com turns that gap into the main product.

That creates an interesting search experience because the user is not asking only, “Is this false?”

The deeper question is, “Was this once considered correct, and what changed?”

That distinction can make the site especially interesting for adults returning to science or history after many years.

Who is IsThatStillTrue.com best for?

The site is best suited to curious adults, students, teachers, trivia fans, and people who enjoy learning why accepted knowledge changes.

Teachers could also use individual examples as discussion starters, although claims should be verified against primary or authoritative sources before being used in formal lessons.

Its quizzes make it easy to explore casually, while its country and graduation-year idea gives the service a personal angle that most fact-checking sites do not have.

The concept also has room to become much more useful if the site clearly shows a source, publication date, previous belief, current consensus, and last verification date beside every result.

That would turn a fun educational tool into something closer to a transparent historical record of changing knowledge.

Is IsThatStillTrue.com worth using?

Yes, IsThatStillTrue.com is worth exploring as a discovery and learning tool, especially if you like finding out which “facts” from school no longer hold up.

Its biggest strength is the simple question behind the whole site: not merely whether something is true, but whether something you once learned is still true.

Its biggest limitation is the small independent web footprint, so users should keep checking important claims against the primary sources the site points toward rather than treating the site itself as the final authority.
