It’s easy to forget that we have access to a virtually limitless resource of information, i.e. the Internet. For a lot of us, this is even true at our fingertips, thanks to the ubiquity of smartphones and an ever-increasing push for online greatness by tech engineers all over the world.

As a result, there are countless websites out there that are geared to make you smarter and more brilliant for either a low or no cost. Here are just 25 killer websites that may just make you more clever than ever before.

1. Duolingo

This isn’t the first time I’ve recommended this language-teaching website (and app), and it certainly won’t be the last. Duolingo is a free version of Rosetta-Stone that delivers the same results: teaching you another language. Regular use of the site can have you speaking and writing Spanish, English, German, French, Portuguese and Italian in a matter of months depending on the diligence you put into it. Hopefully, even more languages will become available soon.

They provide resources for learning pretty much every subject out there, including math, science, history and more. As you learn, the platform will even assess your progress and help you gauge what you’ve learned.

3. Justin Guitar

Guitar is one of the few instruments out there that’s actually pretty easy to learn if you’re a little older, making it one of the most accessible instruments. Still, learning how to play still takes some direction, at least for most people, so a guy named Justin decided he was going to help out. His website provides hundreds of free guitar lessons that range in different styles, depending on how you want to play. His schedule for learning is pretty easy to follow, and the site is a great stepping stone for people wanting to pick the instrument up.
