BaiShou is an open-source, local-first AI memory companion.
You write diaries and life fragments locally, and BaiShou summarizes them layer by layer into “memory rings” that AI companions can understand, search, and keep you company with over the long run. Your data doesn’t go into someone else’s cloud account — it stays on your own devices.
With a pure-white vow, we guard each other for a lifetime.

|---|---|
| Diary | Write in Markdown, with weather, mood, tags, location, and attachments |
| Memory rings | Diaries get summarized layer by layer into weekly journals, monthly reports, quarterly reports, and yearbooks |
| AI companions | Multiple companions, each with its own persona and model, able to call tools to read and write diaries and memories |

| Sync & backup | Incremental sync, full backup, LAN transfer; desktop also has Git version control |
Note-taking tools solve “keep my material tidy.” BaiShou wants to solve “the AI actually remembers me.”
| Note-taking tools | BaiShou | |
|---|---|---|
| Focus | Organizing, backlinks, writing | Personal memory that AI understands and uses over the long term |
| AI | Usually a plugin or a bolted-on chat box | Companions, memory rings, and RAG are the skeleton of the product |
| Data | Often tied to an official cloud or plugin ecosystem | Local by default, with optional sync to your own S3 / WebDAV |
