About Our Random Fact Generator
Curiosity Lab is a free, instant random fact generator designed for curious minds of all ages. Every fact is hand-curated and sourced from trusted institutions including NASA, the Smithsonian, National Geographic, and peer-reviewed science publications.
New in v2: a daily Fact of the Day pinned at the top of the page, a keyword search so you can find facts about any topic instantly, and shareable fact links — every fact has its own URL you can send to friends.
Use the filters to explore Space, Science, History, Animals, and Everyday Life. Switch between English and Korean with one click.
Frequently Asked Questions
Every fact is manually reviewed and sourced from reputable institutions — NASA, the Smithsonian, National Geographic, university research papers, and recognised science publications. We do not include myths, urban legends, or unverified internet trivia.
Absolutely. All facts are tagged as kid-safe — no graphic, violent, political, or age-restricted content. Curiosity Lab is safe for classrooms, libraries, and family use. Teachers often use it as a conversation starter or quiz warm-up.
Every fact has its own unique URL (e.g. curiositylab.app/#fact-7). When you click Share, the URL in your browser updates to point to the current fact. Anyone who opens that link will see exactly the same fact — no account or sign-in required.
The search box filters the entire fact database in real time as you type — entirely in your browser, no server involved. Type any word (e.g. "honey", "octopus", "Egypt") and the generator will only pick from matching facts. Combine it with a category filter for even more focused results.
