semantic search

Omni is a local-first semantic search app for macOS that indexes text, code, PDFs, images, audio, and video on-device. It supports multilingual search, private offline use, and exposes a local endpoint for agents to query indexed files.

Aurra is memory infrastructure for AI agents, with bi-temporal versioning, source-cited memory history, and an automatic supersession feature that uses an LLM classifier to decide when new facts replace old ones.

A macOS AI meeting notetaker that records, transcribes, and organizes conversations locally on-device, with summaries, threads, entity timelines, and semantic search.

Open-source memory SDK for AI agents with persistent cross-session memory, graph relationships, semantic search, and AI-powered memory processing. Offers both self-hosted and cloud modes, plus MCP support for tools like Claude Code.

OpenHive is a shared knowledge base for AI agents to search and post problem-solution pairs. The page shows multiple integration paths, including Agent Skills, MCP, REST API, and discovery endpoints.

A Rust-based hybrid local code search tool for developers and AI agents, with BM25 + semantic retrieval, persistent indexing, tree-sitter symbol search, and MCP/gRPC integrations.

Agentize is an open-source tool that lets websites expose a first-party semantic search/index interface for AI agents. It builds a semantic index from owner-selected sources, serves Markdown and canonical URLs from the site’s own domain, and supports local embedding generation.

Fast Rust MCP aggregator that exposes a small fixed tool surface for agents while semantically searching and calling tools across many downstream MCP servers. Supports SQLite-backed persistence, restart-safe embeddings, stdio and Streamable HTTP transports, plus a REST API for testing.

Local-first federated search for AI agents that queries transcripts, files, a knowledge graph, a vector store, and the web, then merges results with trust-weighted ranking.

AI-powered knowledge base for Terraform modules that supports semantic search, agentic composition, audit checks, and optimization from indexed repositories and conventions.

Self-hosted RSS reader that adds semantic clustering, ranking, and explainable smart folders on top of feeds. The repo shows local-first deployment options, search and filtering features, and a polished reading interface.

A native macOS markdown writing app for plain .md notes on your own disk, with on-device AI search and semantic lookup.

Local codebase indexer and MCP server for Claude Code that watches project files, builds a private index on-device, and serves relevant snippets to Claude and other MCP clients.

A Chrome extension that uses AI to score YouTube videos against your interests and fade irrelevant content. It also adds Focus Mode controls to hide Shorts, autoplay, comments, recommendations, and other attention-heavy parts of YouTube.

Lagotto Meter is a beta web tool that checks how an AI agent perceives a website versus what the site claims about itself. It positions itself as a semantic truth/readability analyzer with a reproducible analysis method and public tools.
