Beaker Browser lets you make sites and have people connect to it via P2P https://beakerbrowser.com/ ; it uses the Hypercore protocol - In a way, it’s an “easier to get into” attempt, since the browser doubles as a “server”

There’s also I2P that works in a similar manner to Freenet and has much greater focus on privacy

Depends on the language? I mean, Portuguese and English are wildly different, so it’s very easy to tell them apart. Now, if it was Portuguese and Spanish, I think telling the two apart could be harder more often
