Membership and Pricing Information
Free to start. A plan buys more time with the figures, and on the higher tiers, debates between them.
Without a plan
Anyone can talk to a figure. Without an account you have one free conversation a day. A free account gives you a monthly allowance of conversations instead, which refills at the start of each calendar month. If you opened a free account before September 2026, this is a reduction: the monthly allowance is smaller in total than the daily one you had. Sessions are short on both. Nothing on this site costs money until you choose a plan.
What a plan changes
- Minutes instead of a conversation count. A plan replaces the free allowance with a monthly budget of conversation minutes. Long conversations and short ones draw on the same budget, so the plan measures what you actually use.
- Longer sessions. Each tier allows a longer single conversation than the one below it.
- Debates, from Magellan up. Choose two figures and a topic, and watch them argue it face to face. Explorer Pro deliberately does not include debates; that is the difference between the two.
A conversation that runs past the end of its budget is allowed to finish; the next one waits for the budget to refill at the start of the month.
Plans and prices
Prices, any trial, and the full feature list for each plan are shown below and at checkout, billed monthly or annually.
Schools, institutions and enterprise
Educator / Classroom — coming soon. A plan for a single teacher or classroom is planned but not yet available to buy. In the meantime, a school that wants to bring pupils in can do so through Institutional access, below.
Institutional and enterprise. For a school, a library, a museum or a company: the longest sessions, the largest monthly budget of minutes, debates, and several concurrent conversations under one account. Institutional access is arranged directly rather than bought above, since most institutions pay by purchase order rather than card. Write to admin@trescointegrations.com with the size of the group and how it will be used, and we’ll set it up.
Pupils under 16. Creating your own account needs you to be 16 or over, but a school with Institutional access can bring younger pupils in: the school holds the account, decides who uses it, and provides the lawful basis for their use — pupils do not register themselves. The arrangement is set out in the Terms of Service.
About the free trial
Where a plan offers a free trial, it is one trial per person, tied to the email address on the account — deleting the account and signing up again does not grant another. Nothing is charged until the trial ends, and cancelling before then costs nothing. Switching to a different plan mid-trial ends the trial and charges the new plan straight away, so finish the trial first if you are still deciding. Full terms are in the Terms of Service.
If your bank is in the UK or EU, read this. Our payment processing does not currently support 3-D Secure, the extra confirmation step some European banks require for a card payment. If your bank insists on it, the charge at the end of a trial — or a later renewal — will fail rather than prompt you, and a failed trial charge returns you to the free plan straight away, with no grace period. You can subscribe again afterwards. Nothing is lost except the plan; your account and favourites stay.
The small print
Subscriptions are billed through Clerk’s checkout. Our own systems never see your card details; they learn only which plan you hold. What we keep about you is set out in the Privacy Policy, and the rules for using the site in the Terms of Service.
