Oii is more than just a hello (in Portuguese, Oii means ‘hi’). It’s our way of introducing you to the Information Integrity Observatory – Climate, Environment, and Democracy.

Our international subscribers call us 'O+double I', and we loved it.


Oii
is restlessness.
After five years of observing and decoding one of the most profitable industries in the world, the lie industry, through our project Mentira Tem Preço (or Lies have a Price, in English), it’s time to reveal what few know, so you can uncover what many want to hide.

Oii is connection.
We’ve mapped out the pieces of this machine built around a single strategy: protecting the interests of a few. Here, you’ll see how it all works.

Oii is community.
There are people using computers and data science to track lies. And others uncovering hidden disinformation in the most unlikely places, like a highway billboard or a t-shirt design. And you’ll be the first to know.

Oii is an invitation.
You’re part of this community now.

P.S.: If you got here through another path, make sure you don’t miss a single Oii.
