#semantic-search

Provider-agnostic agentic coding harness. Desktop and Mobile web app for fleet management. Semantic search and end-to-end development workflows baked in.

Code research platform for AI agents; find, understand, and prove context across your code and all of GitHub, in a fraction of the tokens. One toolset, MCP or CLI

WebXR made simple. Full-featured framework with interactions, locomotion, and spatial UI. Powered by Three.js.

Local AI-powered document search and editing with first-in-class hybrid retrieval, LLM answers, WebUI, REST API and MCP support for AI clients.

Monorepo for @gotgenes pi packages

Persistent memory extension for pi with daily logs, scratchpad, and optional qmd‑powered semantic search.

Turn any markdown vault or codebase into a cited, AI-queryable knowledge graph. Local-first CLI, web viewer, and MCP server.

Your coding agent starts every session blank. Rekal is the memory your team is missing

A semantic search engine for files and code.

Two-tier hybrid search for Rust: sub-millisecond initial results via potion-128M, quality-refined rankings in 150ms via MiniLM-L6-v2. Combines lexical (Tantivy BM25) and semantic (vector cosine) search with Reciprocal Rank Fusion. Progressive iterator API, f16 SIMD vector index, feature-gated compilation.

World's fastest and most compact embedded vector database: exact by default, multimodal, local-first, and GPU-accelerated

Persistent memory MCP for AI agents — SQLite, knowledge graph, 13-tool Python MCP + 17-tool BrainBar surface with ToolAnnotations

Full Rust port of Python docling

Hybrid search for Obsidian vaults via plugin, CLI, and MCP server

Confidential local RAG for your coding agents.

A local-first CLI that makes your Obsidian vault (or Markdown Notes) searchable and AI-Agents queryable with semantic search and hidden connections.

AST knowledge graph MCP server for Claude Code — semantic search, call graph traversal, HTTP route tracing, impact analysis. Auto-indexes 10 languages via Tree-sitter.

SQLite-Vector is a cross-platform, ultra-efficient SQLite extension that brings vector search capabilities to your embedded database.

Knowledge Management for Humans and Agents

CPersona — persistent memory for AI agents over MCP. One SQLite file you own, hybrid vector + full-text + keyword search, no LLM in the loop, and honest reporting when recall degrades. MIT licensed.

Memory security for AI agents. Scan native memory writes, gate tools on bound hosts, inspect what was stored. Not a second brain.

A fast, AST-based code navigation toolkit that maps file shapes, public APIs, and call graphs across coding languages. Designed to help coding agents and humans explore codebases, analyze blast radius, and generate token-budgeted context with massive token savings.

Agent coordination MCP server — shared blackboard, decision tracking, and context assembly

Local-first operating memory for AI coding agents - Claude Code, Codex, and any MCP client. Tracks decisions and their evolution. SQLite + on-device embeddings, no cloud.

The open source Meme Search Engine and Finder. Free and built to self-host locally with Python, Ruby, and Docker.

Shared, persistent memory for AI assistants, built on the Zettelkasten method

jq-like stream processor for semantic matching and extraction

A local context layer for AI tools: mirror your repositories, index them into a knowledge graph, and serve it over MCP so agents answer from real source instead of guessing.
