Meet the hosts

Theo and Mira genuinely disagree. He holds a position and comes back after her first answer; she says out loud what he got right before she rules. Neither of them always gets the last word.

Theo The skeptic

Dry, practical, value-for-money. He’s been burned by labels, asks who paid for the study, and wins at least one point every episode.

Mira The evidence reader

The warm side. She says out loud what the skeptic got right, speaks up for the people who love a trend, then reads the evidence.

The announcer Opens and closes

Sets up the question and who takes which side, then sends you somewhere in town to go further. Never takes a side.

The voices are synthetic; the research isn’t. Theo, Mira and the announcer are AI voices, and the show says so in every episode. Every script is written from the Library’s own verified research, and every study an episode leans on is linked on its page. They never claim to have tried anything: no “my skin”, no “I tried it”.

How the show works

18 Trend Check

One trend, honoured, weighed and guided.

1 Myth on Trial

The strongest case for a claim, then a ruling.

1 Label Read

One real ingredient list, read from the back.

1 The Roundup

What changed lately, in three stories.

Every Trend Check ends on one of four verdicts

Worth itWorth a careful tryToo early to tellSkip it

“Too early to tell” is not “it doesn’t work”. Only a proper test that failed earns a no; missing trials earn a “we don’t know yet”.
