semantic-search — independent software & tools
-
session-recall
Shared memory for Claude Code and Codex. Your agent recalls decisions from weeks ago — including what the other engine worked out. Local semantic search over both histories, as MCP tools.

LexonGraph
LexonGraph is a log-structured semantic index that stores embeddings as immutable blocks in navigable vector graph. It supports local and cloud backends, fast centroid-guided search, and efficient period rebuilds, enabling LLMs to retrieve precise context from large archival corpora.
