Memory is usually about the past. But in EverMemOS, memory also serves the future. Foresight is a specialized component of the MemCell that allows the system to store predictions, plans, and expiring information, enabling the Agent to be proactive rather than just reactive.

​
What is Foresight?

Foresight deals with Prospections—inferences about future states derived from current interactions.
  • User says: “I’m going on vacation next week.”
  • Traditional Memory: Stores the text “I’m going on vacation next week.” (Becomes outdated in 7 days).
  • EverMemOS Foresight:
    • Inference: User will be unavailable.
    • Start Date: [Current Date + 7 Days]
    • End Date: [Current Date + 14 Days]
    • Action: Suppress work notifications during this interval.

​
Validity Intervals

Every piece of knowledge has a shelf life. Foresight introduces the concept of Validity Intervals (tstart,tend)(t_{start}, t_{end}).

Short-term Validity

“I’m in a meeting right now.”
  • Valid for: 1 hour.
  • After 1 hour, this fact is archived or marked as “past context” so it doesn’t confuse future queries.

Long-term Validity

“My office is in Berlin.”
  • Valid for: Indefinite (until contradicted).
  • The system assumes this is true for all future interactions unless explicitly changed.

​
Enabling Proactivity

Foresight transforms the AI from a tool that waits for commands into an assistant that anticipates needs.

Use Cases

  1. Contextual Reminders:
    • Scenario: You mentioned on Monday that you need to buy a gift by Friday.
    • Action: On Thursday, the system checks its Foresight store, sees the impending deadline, and proactively asks: “Do you still need help finding that gift?”
  2. Conflict Detection:
    • Scenario: You try to schedule a meeting for Tuesday.
    • Action: The system checks Foresight, sees a “Doctor’s Appointment” prediction for that slot, and warns: “You might have a conflict with your appointment then.”
  3. Adaptive Behavior:
    • Scenario: You tell the AI “I’m focusing on coding this week, no distractions.”
    • Action: The system sets a “Coding Mode” foresight flag. For the rest of the week, it gives shorter, code-only answers and suppresses chit-chat.
Foresight is what makes EverMemOS feel “intelligent” over time. It doesn’t just remember what you did; it understands what you are going to do.
