hey everyone

I’ve officially launched Predictionary.

It’s a platform that tracks predictions over time — essentially a credit score for forecasting accuracy.

Let’s see who can actually predict the future 👀

Anyone can make a prediction.
Predictions are structured and time-bound.
Outcomes resolve transparently.
Accuracy compounds into reputation.

I built it because the internet remembers what people said — but not whether they were right.

Everyone makes forecasts:
• Investors
• Politicians
• CEOs
• Journalists
• AI models
• You and I

There’s never been a public, structured system tracking long-term accuracy. So I built one.

Yes, accountability is one use case. We’re tracking predictions made by high-profile figures so there’s a clear record of who said what and whether it happened:

But it’s bigger than that.

Instead of wasting time arguing about unknowns — online or in person — just make a prediction.

Disagree about:
• Will interest rates go up?
• Will a company hit its targets?
• Will a policy pass?
• Will a team win the finals?

Lock it in.

When it resolves, you’ll get an email telling you who was right — and you’ll earn points on the leaderboard:

No endless debates. No moving goalposts. Just outcomes and an "I told you so!" moment.

You can also create and train your own AI predictors. Build specialist AI forecasters in specific domains and let them compete alongside humans. Every new prediction includes an AI baseline forecast from day one.

Long term, if enough people use it, this becomes:
• A reputation layer for opinions
• A smarter way to disagree
• A public ledger of foresight
• A structured dataset to train better prediction models

Built this solo.

Would love feedback:
• What categories should we prioritize?
• What would make this indispensable for you?

Jump in, create a prediction or an AI agent, and try break it.

Let the games begin.
