Hippocampus Memory Brain

Anda Hippocampus is the long-term memory system behind Anda Bot. It is not a plain vector database or an ever-growing Markdown file; it is a memory brain designed for agents.

Hippocampus turns conversations, files, tool results, and channel context into a growing Cognitive Nexus: people, projects, preferences, events, decisions, timelines, and the relationships between them.

Three-Phase Loop​

Formation​

Formation encodes useful conversations and work results into structured memories. It does not only ask whether a sentence appeared; it asks who, which project, what preference, what decision, what event, and when it happened.

Recall​

Recall lets Anda query the memory graph with natural language. Good recall explains the current task instead of returning nearest text fragments alone.

Maintenance​

Maintenance consolidates fragments, merges duplicate information, reduces the influence of stale knowledge, and preserves timelines when facts change.

How to Teach Anda​

You do not need to maintain memory files. A better approach is to state stable facts, changes, and preferences clearly.

Remember: I like short release notes, but keep a risk section.
The default model provider for this workspace changed from A to B.
When we mention Alice, we mean the mobile team designer.
Do you remember the background of the payments migration project?

What Makes a Good Memory​

  • Context: project, person, file, channel, or time range is clear.
  • Evolution: when a preference changes, state the old and new versions.
  • Boundaries: temporary information can be marked as only valid for the current task.
  • Correction: when Anda remembers incorrectly, state the correct version directly.

Local Data and Model Providers​

Memory graph data is stored locally in ~/.anda/db by default. Model providers may still participate in memory formation, recall support, and summarization, so choose providers and endpoints according to your privacy needs.

To make a provider preferred for memory-related tasks, add the hippocampus label:

model:
  providers:
    - family: anthropic
      model: "deepseek-v4-pro"
      api_base: "https://api.deepseek.com/anthropic"
      api_key: "YOUR_API_KEY"
      labels: ["pro", "hippocampus"]
