This is the Guardian.

Hey, it's Mike.

Today in focus is off this week, so instead we're bringing you Black Box, a series we made earlier this year,

about the way AI is reshaping our world.

This is episode 2, our investigation into Cl off, a deep fake porn app that's been used to

humiliate and bully young women.

We find out how lawmakers are struggling to control these kinds of apps and try ourselves to track down the shady figures who created it.

Today in focus we'll be back on September 2nd and over the next few days you'll be able to listen to every episode of Black Box on this feed.

Hope you enjoy it. Before we begin just a heads up today's episode contains a little bit of swearing.

Straight up here and right.

Okay.

For the last few months, I feel like I've been wandering through a hall of mirrors.

Especially on this one day a few weeks ago

when I was walking around London with producers Josh Kelly and Alex Aetac, Looking for an AI business who by this point we've been trying to track down for months.

Should we push the button?

Let's do it, yeah.

Finding ourselves in dark basements of Victorian buildings.

My name is Michael. I'm a journalist. I'm looking for a business.

In winding corridors of faceless office blocks.

Unfortunately, I won't be able to give you any details,

but they're not located in here.

Knocking on doors with handwritten labels and nobody behind them.
