Important plan details

The prices and allowances shown are the immutable V1 offering used by secure checkout. Team includes four members and can grow to ten using the pricing shown for additional members. Pro includes ten members and can grow to 50. Its value is the larger structure for multiple teams, expanded solution library, advanced governance, greater storage, dedicated AI infrastructure, and higher compute allowance, not simply another seat.

Workspace limits apply to active workspaces. Until workspace archiving is available, every workspace that has not been deleted is treated as active. The Decision Tool Library row describes the breadth of solutions in each plan, while Active and Archived Models & Tools have separate retention limits. Knowledge Storage includes RAG knowledge and vector index capacity. Paid checkout becomes available when the deployment has a complete Stripe V1 configuration; signed provider confirmation, never the browser return, enables access.

AI Infrastructure describes how compute is deployed, not who can access organization data. Organization data remains separated in every plan. Plus uses shared managed infrastructure, Team uses private managed infrastructure, Pro uses infrastructure dedicated to the organization, and Enterprise deployment is defined by agreement.

Questions before you choose

More than a chatbot. A place to make decisions.

See how Albarena turns AI assistance into persistent, reviewable decision work, and understand what changes when you subscribe.

Why Albarena

Why choose Albarena instead of a general AI assistant?

General AI is useful for quick answers and drafting. Albarena is built for the work that follows: framing a situation, connecting evidence and perspectives, applying transparent decision methods, comparing possibilities, and preserving a rationale that people can inspect, challenge, and improve.

Does my work disappear when a conversation ends?

No. Your work is saved in decision workspaces with its files, references, notes, assumptions, models, and outputs. You can return later, add evidence, revise the analysis, and continue from the shared context instead of reconstructing it from an old conversation.

Can I understand and challenge how a result was produced?

That is a core purpose of Albarena. Key inputs, assumptions, variables, interactions, methods, and outputs remain visible so people can examine the reasoning. AI can summarize, structure, compare, and suggest next steps, but its assistance remains reviewable and people retain the final judgment.

How do teams collaborate in Albarena?

Organizations organize shared work into groups and decision workspaces. Teammates can examine the same evidence, refine assumptions and AI suggestions, apply decision methods, and review outputs within a common context. Collaboration features and capacity depend on the selected plan.

Does Albarena replace the other AI tools I already use?

Not necessarily. General AI tools can remain useful for ideation or drafting. Albarena provides the structured decision environment around that intelligence: connected evidence, explicit assumptions, transparent methods, shared review, and a durable rationale that your team can test and develop.

Who remains in control of the decision and the data?

You and your team retain responsibility for reviewing inputs, accepting changes, and making the final decision. Work stays in the personal or organization context where it was created. Review the current Privacy Policy and Terms for details about access, retention, export, deletion, and service providers.

Starting, plans, and billing

Can I start for free before subscribing?

Yes. The Individual Free plan provides a permanent personal space with no payment required. It is designed for learning, early exploration, and limited individual decision work. Choose a paid organization plan when you need more capacity, broader tools, or collaboration.

Which plan should I choose?

Choose Free for exploration, Plus for deeper individual work, Team for one collaborating team, Pro for multiple teams and advanced governance, and Enterprise for negotiated requirements. The comparison above shows the current member, workspace, storage, tool, AI, and governance allowances.

What do paid plans add beyond Free?

Paid plans progressively add more workspace and knowledge capacity, a broader decision tool library, expanded AI capabilities, specialist assistance, and data tools. Shared plans also add collaboration, integrations, and governance. The exact combination varies by plan, so use the comparison above for current allowances.

How do billing periods and additional members work?

Monthly plans are prepaid one month at a time. Current fixed price annual plans are prepaid for the full service year. Team and Pro include members and support paid additional members up to the displayed plan maximum. Review the order summary, renewal period, and taxes before paying.

How do promotions and free trials work?

Eligible offers are shown with their duration and regular price. Automatic offers apply at checkout; a valid entered code may replace one because offers do not stack. Trials require a payment method, and regular billing begins afterward unless canceled. Checkout performs the final eligibility check.

Can I cancel my subscription?

You may cancel automatic renewal at any time. Service normally continues through the paid billing period, or through the trial boundary when applicable. Partial period refunds are not automatic and remain subject to the published refund policy and applicable law.
