About SanityCheck

We're your personal logic checker. Whenever you're reading any news article, science article, or finance blog, there are probably some logical fallacies that might skip your notice.

It's easy to use: just install the extension, and give it a click whenever you're reading something. It'll highlight the main issues, saving you from misinformation.
