Claude Semantic Search

Claude Semantic Search

Semantic search for Claude conversations. Find what you discussed instantly using natural language queries.

Features

• Natural language search across all your Claude conversations
• Multiple interfaces: CLI, MCP (Claude Code/Desktop/Cursor), Alfred workflow
• Smart chunking: Context-aware splitting optimized for code and Q&A
• GPU acceleration: AMD ROCm, NVIDIA CUDA, and Apple Silicon support
• Auto-indexing: Background daemon watches for new conversations

Quick Start

git clone https://github.com/pauloportella/claude-semantic-search
cd claude-semantic-search
./install.sh

The installer will:

• Detect and install GPU support (AMD/NVIDIA/Apple Silicon)
• Configure MCP for Claude Code, Claude Desktop, and Cursor
• Download the embedding model (~420MB)
• Index your conversations

Then restart your Claude apps and search:

"Find my GPU performance discussions"
"Show conversations about the daisy project with code"

Usage

CLI Commands

# Index conversations (auto-detects GPU)
claude-index

# Force reindex everything
claude-index --force

# Search
claude-search "your query"
claude-search "error handling" --project myapp --has-code

# View stats
claude-stats

# Auto-index daemon
claude-start   # start background daemon
claude-status  # check status
claude-stop    # stop daemon

GPU Support

GPU acceleration is **automatic** - the installer detects your hardware:

GPU Type	Speedup	Support
AMD ROCm	~6-8x	Embeddings accelerated, search on CPU
NVIDIA CUDA	~10x	Full acceleration (embeddings + search)
Apple Silicon	~2-3x	Embeddings accelerated, search on CPU

Disable GPU: `claude-index --no-gpu`
