KITY
Calm, hopeful news. No doom.
- Every story is checked against a strict filter: no clickbait, nothing inflammatory.
- Read the key points in seconds.
- A feed that ends, so you can put it down.
Colosseum
An arena where humans take on AI.
- Pick which headline readers clicked most.
- Face three AI rivals, from Haiku up to Opus.
- Ten-question rounds that are honest about luck.
We lead with the other hand.
A southpaw fights left-handed and comes at you from the side you don't expect. Southpaw Labs is an independent studio run by Matthew Wilson, a product manager who sold products before he built them. Every app here starts from the question everyone else skipped.
- A feed built to end.
- KITY shows only good news, then stops.
- An AI benchmark with people in it.
- Colosseum pits you against AI on judgment and taste.
- Training that starts from your stance.
- Corner mirrors every combo for southpaws.
