Our patented system reveals what children learn from every programme — words read, tricky spellings, and new vocabulary.
It turns entertainment into education and makes the learning visible to parents.
In a world where children’s content is everywhere and often free, Caterpillar Captions creates real differentiation.
Platforms can show parents exactly what their child is learning - words read and vocabulary gained, making the value of their service clear.
We see children’s watch-time increase by up to 3%. Parents actively choose great content that helps their children learn too.
Children’s content becomes a retention engine. It’s not just entertainment, it’s a visible investment in children’s future.
Akili TV’s children’s audience grew 14.9% in a single month - and parent viewership by a staggering 39%, reaching 2.8 million viewers.
Adopting Caterpillar Captions is a clear differentiator - proven to be trusted by parents, schools, and governments.
+14.9% Viewership for the segment grew from 1.3m to 1.5m
+39% Parent audience grew from 0.92m to 1.3m
“Parents are clearly engaging with the content and discussing it with their children. That’s powerful educationally, but it’s also commercially significant. Co-viewing is critical for advertisers, and this is the strongest performance we’ve ever seen in this market.”
Jesse Soleil, President of Akili TV
