What it does

DejaView gives your AI a persistent knowledge graph it can read from and write to across sessions. Unlike flat context windows that reset every chat, the graph grows over time.

Tool	What it does
agent_context	Load a full memory summary at session start
remember	Store a fact (subject, predicate, object)
remember_many	Store multiple facts at once
recall	Get everything known about an entity
search	Find entities by name
ask	Natural language Q&A over the graph with citations
timeline	See recently stored facts
graph_stats	Entity and relationship counts
share	Generate a public shareable link for any entity
forget	Remove a specific fact
forget_entity	Remove an entity and all its connections

Example

Once connected, just chat naturally:

"Remember that Alice is the lead on Project Atlas and prefers async communication."

The agent calls remember() automatically. Next session:

"What do I know about Alice?"

The agent calls recall("Alice") and tells you everything — including things you told it months ago.
