Kanon is free, and the part most people use is the part that stays free: the whole board, the fair price under every book, and a price check on any market, with no account. Pro is for people who look at this every day, and it adds two things - the current board rather than one held back, and a kept record of the prices you got.
The line between the two is time and memory, never the read itself. Every price, every fair value and every check is free today and needs no account. What is stated here is what it costs now, and a change to it would be announced before it applied.

Pro is not open yet. The prices above are what it will cost. There is nothing to buy on this page today, and everything described in the Free column is already live and stays free.
◆ The current board, not a held-back one. Free sees the same board Pro sees, about 15 minutes later. Nothing is hidden and nothing is blurred — it arrives later. Prices on both venues move, and a number that was accurate a quarter of an hour ago may no longer be the number on the screen in front of you.
◆ Your price record, kept and broken down. Kanon compares a price you recorded against that market’s closing line — the last valid price before the market closed. Free keeps your last 10 entries and the all-time summary. Pro keeps all of it, splits it by side and by the price you paid, and exports it. It is a record of prices you already got. It is not a suggestion, and it never says what to do next.
Kanon publishes how its own posted prices have resolved, and the number is negative: -1.77% per dollar across 471 settled markets since 2026-07-03, net of venue fees and half the observed spread, with a 95% interval of -14.22% to +9.76%. That is on this page, on a page asking for money, because a service that only published its good numbers would not be worth paying for. Pro does not change that figure and does not claim to. What is described above is the current board and your own record — not a result.
The full accuracy record, including where our probabilities are worst, is at /accuracy.
Does Kanon promise a return? No, and it could not. Kanon publishes prices and its own record — including the part of that record that is negative, above. It places no orders, it holds no funds, and it says nothing about what anyone should do. Nothing here is advice.
Can I use Kanon without paying? Yes, and without an account. The board, the fair price under every book and a price check on any market are free, with no trial clock and no expiry date on them. That is the arrangement today and there is no plan to change it. It is worded that way on purpose: a one-person product should not make open-ended promises about years it cannot see, and a commitment that might have to be broken is worth less than none.
Is there a discount for a year? $149 for twelve months against $15 a month. That is the only difference between them; the two include the same things.
Where do payments go? To Whop, which hosts the checkout and is the seller of record. Card details never reach this site. Kanon receives only the fact that a payment happened.
What happens if I cancel? Access to the Pro parts ends when the period you have paid for ends, and your account and the markets you follow stay exactly as they are. Your price record lives in your own browser, so cancelling does not touch it and neither can we.
