Pick the better AI answer.
Get paid.
Two AIs answer the same real question. You pick the one you like more, without knowing which model wrote which. Every pick pays, and together the picks reveal which AI people actually prefer.

The models reveal instantly, and every pick adds to your earnings.
What this actually is
Every pick is a blind vote.
On its own, one pick is just your taste. Millions of blind picks are something no benchmark can measure: which AI people genuinely prefer when the brand names are gone. That preference map is what sides is really building.
This is a measure of preference, not trust. We are not asking which model you believed or which one you would rely on. We are asking a simpler, harder question: read blind, which answer did you actually like more. Strip the logos off and the honest signal is left.
The earnings ledger is early. So there are no user counts or totals to quote here yet. What is real today is the mechanism: you judge blind, the picks add up, and the preference map takes shape from there.
Why the picks matter
Labs spend enormous effort guessing what people prefer. Blind picks measure it directly. Every pick you make is a vote about the answer in front of you, and in aggregate those votes reveal something no leaderboard captures: which AI people actually prefer.
AI labs
Teams shipping models want to know which answers real people choose, not which model wins a benchmark. Blind picks tell them that directly, one pair at a time.
Researchers
Preference between models, measured without the brand attached, is a clean signal. It says what people actually like when nothing tips them off.
Anyone choosing a model
Builders and buyers deciding what to run get an honest read on human preference, gathered the same way for every model, with no thumb on the scale.
Public leaderboards
Rankings get gamed, and even honest ones carry a brand halo. People rate the badge as much as the answer, so the number tells you who is trusted, not what is preferred.
Blind picks
No name, no logo, no hint. You judge the writing on its own, so the pick is about the answer and nothing else. That is the only honest way to measure preference, and it is the whole point.
Forward-looking and simple. As more people judge, the map of real preference gets sharper. That map is the product.
You get paid to judge
Every pick earns SIDES, the token behind sides. Earnings accrue as you judge, and you claim them when you are ready.

The straight answers to what people ask before their first pick.
No. Judging is anonymous-first, so you can start picking right away with nothing to sign up for. Sign in with Google only if you want your history and earnings to follow you across devices.
You don't while you pick, and that is the whole point. Both answers are unlabeled so you judge the writing, not the logo. The two models are revealed the moment you choose.
We aggregate them into a preference map that shows which AI people actually prefer when the names are stripped off. No personal data is required to judge. Full specifics are in the docs.
Every pick adds a small amount of SIDES to your balance. Earnings accrue as you judge, and you claim them when you are ready. Sign in first if you want that balance saved to your account.
No. The two sides are randomized and unlabeled every round, so blue and red carry no fixed identity. Which model lands on which side changes each time you play.
SIDES is the token you earn for judging. It accrues as you pick and can be claimed when you choose. The honest details, including how it works, live in the docs.
