memex

Named for Vannevar Bush's 1945 vision of an "enlarged intimate supplement to memory."

When to Use

• Looking back on past decisions: "where did I decide on auth?"
• Finding patterns across conversations
• Building a searchable corpus of collaboration history
• Running SQL queries against your AI interaction data

Quick Start

# Ingest a Claude.ai export
memex ingest ~/Downloads/claude-export.json

# Search with hybrid retrieval (keyword + semantic + reranking)
memex dig "authentication decisions"

# View what's in your corpus
memex corpus

# Power-user SQL escape hatch
memex query "SELECT COUNT(*) FROM fragments"
memex sql  # Interactive shell

Design

• dig is the default — hybrid search that just works (BM25 + semantic + cross-encoder reranking)
• SQL for power users — query and sql for when you need full control
• Source-agnostic — Claude, OpenAI, more to come. Adding a source = one adapter
• Local-first — corpus stored at ~/.memex/corpus.duckdb, project-local with .memex/
