## What it is
msgvault is a Go application that archives a lifetime of email, chat, calendar, and meeting data into a local SQLite/DuckDB store, supporting Gmail, IMAP, Slack, Discord, Teams, and imports from MBOX, PST, and Apple Mail. It provides fast offline keyword and semantic search, analytics, a Web UI, a TUI, and an MCP server for AI agent queries over the archive.

## Use cases
- back up my entire Gmail history locally
- search years of email and Slack messages offline
- import old MBOX and PST email archives
- query my message history with an AI agent via MCP
- analyze who I email most with analytics
- archive Discord and Slack conversations
- find attachments buried in decades of email

## When to choose
- you want a complete local, privacy-preserving copy of your email and chat history
- you need fast offline search and analytics across many message sources
- you want read-only AI agent access to your archive via MCP without send capability

## When to avoid
- you need an email client that can send or reply to messages
- you require production-grade stability - the project is explicitly alpha with changing formats and APIs
- you need a hosted multi-user archival service rather than a personal local tool
