Wikipedia
The free encyclopedia — we link the specific pages worth a detour, not the whole site.
Wikipedia doesn't need an introduction, so this page isn't a review of it. What we feature are individual pages that double as genuinely interesting rabbit holes on their own — the Spinning Dancer illusion, the 2015 dress that broke the internet, the checker-shadow trick your brain refuses to believe even with a ruler in hand. Free, ad-free, and edited by volunteers since 2001.
