User guide

You want to use Particles to manage knowledge — deposit sources, extract claims, query, export.

This guide is task-oriented: each page walks you through one job end-to-end. Read Getting started first; the other pages are reference-style and you can dip into whichever you need.

Page	When to read
Getting started	First-time setup → first query
Concepts	What's a particle, subject, status, confidence, provenance
Querying	Semantic search, tag filters, structural filters, MCP, what the ranking does
As-of time travel	What the store believed at a past instant, and what replaced it
Exporting	Obsidian vault, Anki deck, wiki articles, Logseq graph
Graph view	The scoped epistemic subgraph as a self-contained HTML file
Using from LangChain	Consume a Particles store as LangChain tools / a retriever
Claude Code memory	Wire a store in as managed agent memory — session-start push, session-end harvest
Swapping in for the reference memory server	Drop-in replacement for @modelcontextprotocol/server-memory
Depositing from your phone	Deposit URLs from the iOS Share Sheet via HTTP or an iCloud inbox file

For operator-side concerns (long-term tuning, lint hygiene, troubleshooting), see the operator guide. For writing a new extractor or exporter, see the plugin-author guide.
