What you can do in Foresight on the web

1

Back YES or NO with play-money credits

Every market has a crowd probability. YES shares cost the price, NO shares cost one minus it, and a trade nudges the price in log-odds space just like the iPhone app.

2

Your forecast is scored, not your bet

You state your own probability of YES on a slider. That number — not the crowd price — is what your Brier score, accuracy and calibration curve are built from.

3

20 timeless training markets

The full general-knowledge bank across Science, Tech, World, Culture and Sports, each with a definite answer you reveal when you are ready to be scored.

4

Calibration dashboard

Brier score, directional accuracy, calibration error, win streak, a bubble-plot calibration curve against the ideal diagonal, and a read on your confidence bias.

5

Today hub with levels, XP and streaks

Level titles from Rookie to Superforecaster, a daily bonus that scales with your streak, a Daily Challenge, crowd movers and 13 unlockable badges.

6

Quick Play and your own markets

Run the deck one card at a time with YES / NO / Skip, or write a market of your own and settle it yourself when you know the answer.

Questions

Is the web version of Foresight free?+

Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.

Where is my data stored?+

Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.

Do I need an account?+

You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.

How is the web version different from the Foresight iPhone app?+

The iPhone app pulls live real-world markets with real crowd odds from a public prediction-market feed; the web version never touches the network, so it runs on the 20 timeless training markets plus any market you write yourself. Quick Play uses YES / NO / Skip buttons instead of the iPhone's swipe-and-haptics card deck. There are no push reminders, share cards or unlock celebrations in the browser.
