Your AI operating system, with persistent memory — not just a chatbot. MOS remembers your documents, decisions and goals, and keeps working on them between conversations. Your data and your AI keys stay yours.

Bring your own AI. Your AI usage stays on your provider account. Hosted MOS runs on your own OpenRouter key and the models you choose — AI provider usage is billed by that provider, not by Moseisley.

The 7-day trial needs no card and never turns into a charge by itself. The MOS subscription is billed through Stripe and can be canceled anytime from the customer portal. AI provider usage is billed separately by your chosen provider using your own API key.
