Medical results — cross-check interpretations before a doctor's visit
Decisions — get a range of arguments before committing to a choice
Contracts & documents — spot what one model missed
Creative work — collect five directions instead of one

Your conversations stay yours

MF0 is not a middleman that stores your chats in some corporate cloud. Your data lives where you want it — private by design. No profiling, no training on your conversations.

Memory that grows with you

The Memory Graph connects facts, people, and ideas across all your conversations — automatically. Ask any model about something you discussed weeks ago and it will know.

Know exactly what you spend

Real-time cost tracking across every model and every conversation. See token usage, compare model prices, and stop paying for more than you need.
