A self-hosted personal memory graph over Chinese-native data — WeChat / QQ / email / documents / audio. This repository is the open demo. The full engine is a separate proprietary product.

What this is

memexa turns scattered, multi-party Chinese data into a queryable memory graph: every message is stored verbatim, extracted into structured cards, and every answer is cited back to the original sentence. It is fully self-hosted — your data never leaves your machine.

This repository ships the open demo: a small synthetic dataset and a stub extractor, so you can see the shape of the project in thirty seconds — no backend, no API key, no configuration.

Try the demo

pip install memexa
memexa demo

Six synthetic sources (WeChat / QQ / email / browser / AI chat / audio) are ingested with the stub extractor, then five sample queries run against the resulting cards — entirely in memory. This is the honest first look at what the project does.

The full engine

The demo runs a stub on synthetic data. The full memexa engine is a proprietary product and is not included in this repository. It adds:

• Live ingestion of your own data across multiple sources, incremental.
• A two-LLM extraction pipeline producing cards with per-claim citations and cross-alias canonical identities.
• A multi-channel recall stack with cross-encoder re-ranking — built for high-accuracy retrieval over messy, multi-party Chinese chat, not a single-vector lookup.
• An MCP server + CLI, so any coding agent (Claude Code, Cursor, Cline, Codex) can use your memory as a first-class tool.
• A local desktop app — runs the whole stack on your own machine.
