Local-first · Runs on your machine

Your second brain for prediction markets

A private log of every prediction you make — or get sent by someone else — checked automatically against what actually happens.

Write down your reasoning the moment you place a trade. Chad grades it once the real-world result is in, so over time you can see who’s actually good at this — including you.

How it works

From a hunch to a sharper second brain

Every trade follows the same loop — logged once, tracked automatically, scored honestly.

1

You get a reason to believe something

A friend's tip, a Discord call, a headline, or just your own hunch about how something plays out — a game, an election, whether the Fed cuts rates.

2

You back it with real money

Prediction markets like Kalshi let you bet on yes-or-no questions about real events, at real odds — you place that trade.

3

You write down why, in Chad

Your reasoning, how confident you are, and where the tip came from — yourself, a friend, a Discord group — logged right alongside the trade, in seconds.

4

The real world decides

The game ends, the vote gets certified, the number comes out — whatever the question was, it gets a real answer, and the market pays out.

5

Chad tells you if you were right

Automatically — no spreadsheet to update. It scores the call against what you predicted, and against everyone else's track record too, not just this one bet.

6

You get sharper every time

Every graded call builds your history. Share results, export the data, and see the patterns — including which sources, yourself included, are actually worth trusting.

01 — Graph

Every trade becomes a node

Kalshi trades import automatically and organize themselves by category — sized by how much is riding on them, colored by outcome, with the real dollar amount right on the node.

02 — Tracking

Every pick sharpens the next one

Log a thesis every time you have one, and Chad builds the running record for you — the pattern in what you've tracked is what actually refines your prediction market picks over time.

Local-first, yours

A thesis isn't just a bet — it's the specific read that got you there, the alpha that's yours alone. Local-first keeps it that way: everything lives on-device by default, exportable as plain Markdown you (or any other tool) can read without this app. Nothing shared unless you choose to.
