# Chronos

> Use this tool when you need to enable AI assistants to retain information across conversations and provide contextual understanding. Chronos solves the problem of knowledge loss between chat sessions, allowing for persistent memory and semantic search. It is ideal for use cases where AI agents require local data storage and project management capabilities, with inputs including user queries and project data, and outputs including recalled information and suggested next tasks.

## Description

Gives AI assistants persistent memory across chat sessions using SQLite-backed storage with TF-IDF indexing for semantic search. Includes tools for remembering, recalling, updating, and forgetting information, as well as temporal queries. A built-in knowledge graph organized in hyperbolic space enables tracking project events, constraints, and causal relationships, with tools for suggesting next tasks and analyzing project structure. All data stays local with no cloud dependencies.
