Can I buy a subscription right now?
New paid subscriptions and upgrades may be temporarily unavailable while paid acquisition is paused. Current purchase availability is shown on the plan cards and at api.socratic.one/api/v1/subscriptions/availability. Existing subscribers can still manage billing or downgrade. The Free plan remains available.
Do I need my own API keys?
Your first platform AI debates do not need a key. To select OpenRouter models, connect your OpenRouter account using OAuth-PKCE or enter an OpenRouter key. Pro uses your OpenRouter connection. Your OpenRouter key is stored in your browser. It is sent over HTTPS to our backend for model calls. For streaming, a temporary server cache can retain it for up to 5 minutes and deletes it when used. It is not saved in your account database.
How do I manage billing or cancel a subscription?
For an existing paid subscription, open Settings, then Subscription. Manage billing opens the Stripe customer portal. Choosing Downgrade to Free requests cancellation at the end of your billing period. Review the confirmation before leaving the page; manage your subscription before closing your account. OpenRouter usage is billed separately by OpenRouter.
What happens when I hit my Free plan limit?
Free includes 3 platform AI debates per month and 25 AI rounds per month. Monthly allowances reset at the start of the next calendar month. After the no-key debates are used, connect OpenRouter while your round allowance remains, or wait for the reset. The discussion history list is available on Basic and Pro; Free does not include it.
