Plans, limits, and billing

EidoStack offers Free and Pro access to its AI Playground. Your plan controls which workspace features and limits apply; it does not include AI model credits. Requests made using your own OpenAI, Anthropic, or Google AI API keys are billed separately by those providers.

Compare the available access levels

Both plans let you chat with models, explore prompts, compare responses within the applicable limits, and inspect token usage, context, and estimated cost. Free lets you try the core Bring Your Own Key (BYOK) Playground experience with one provider and the limits above. Pro expands workspace access; neither plan includes provider API credits.

View the current subscription

Open workspace settings and select Subscription. The page shows the active plan and its current status. A Pro account shows its billing period, current price, next renewal or access-end date, and the included features.

The product currently displays Pro pricing as $10 per month or $99 per year, but checkout is not enabled in the application. When you are on Free, Request Pro access explains that preview access is handled through support rather than by an in-app purchase flow.

Provider billing remains separate. Connecting a second provider or sending a request can incur charges from that provider even if your EidoStack plan is Free or Pro.

What happens at a limit

EidoStack checks limits when you configure providers, create chats, and save messages. Comparison uses the existing chat and message limits. If a Free limit is reached, the workspace explains the restriction and directs you to the subscription area. Existing chats and saved messages remain available; the limit blocks the next action that would exceed it.

For example, a Free account cannot save a second configured provider, create a sixth chat, or add the 51st user message to a chat. You can still try different models and compare their responses in each of your five chats using your configured provider. Request Pro access if your Playground usage requires more providers, chats, or messages.

Cancel active Pro access

An active Pro subscription can show Cancel subscription in the subscription panel. The confirmation dialog explains the period-end date before you confirm. When cancellation is accepted, Pro features remain active until the current billing period ends; the account then returns to Free limits.

The cancellation button is shown only when the subscription can be cancelled through the current account flow. If cancellation is not configured for a particular subscription source, use the support path shown in the product rather than assuming the provider billing method has been cancelled.

Cancellation does not delete workspace data, revoke provider API keys, close provider accounts, or stop provider charges. Manage those separately. For help with account or access issues, see Contact support.
