Organization context
Choose the organization for this app’s saved work and AI Q&A. Membership alone does not authorize billing; payer access is checked separately. Nothing is enrolled or charged by this choice.
Organization-funded AI requires an explicit organization and authorized payer. Personal credits are not a fallback.
