Semantic memory
Semantic memory is an AI agent's stored knowledge of general facts about a person or the world, kept apart from the events they came from. It answers questions like what a person's budget is, not when they said it.
What semantic memory is
Semantic memory holds facts that stay true across conversations. Examples include a customer's company, a preferred language, or a project budget.
Why it matters
- A fact like a budget changes over time. Say Nadia at Acme moves the budget from 32k to 40k. The agent needs the current value, and the earlier value is still useful when someone asks what it was on a given date.
- Facts without their source are hard to check. Keeping the source makes a fact easier to trust.
How it works in Harny
- Harny gives each person a private memory the app's AI can read. Memory is dated and each result lists its sources.
- A changed value with a newer timestamp becomes the current value. The earlier value stays answerable by date.
- Recall returns results with an id, rank, occurredAt, content and sources.
Is semantic memory the same as a chat history?
No. A chat history keeps the events. Semantic memory keeps the general facts that come out of them.
