## Project history and usage

msgvault is a local-first archive, search, analytics, and AI-query tool for personal message history, created by Wes McKinney and published by Kenn Software LLC. McKinney's February 2026 announcement describes building it after years of using Gmail and wanting local control over decades of email, attachments, and messages. The announcement says the project began as a hybrid Python/Rust effort and moved to a single-language Go project that ships as a static binary.

### How it is used

The architecture centers on downloading messages into a local archive, then querying them without live mailbox access. The docs describe Gmail, IMAP, Microsoft 365, PST, MBOX, Apple Mail, WhatsApp, iMessage, Google Voice, Facebook Messenger, and SMS Backup & Restore imports; SQLite is the default system of record, DuckDB and Parquet power analytics, SQLite FTS5 powers keyword search, and optional vector search can use a configured local or self-hosted embedding endpoint. The CLI exposes sync, import, search, TUI, MCP server, HTTP server, analytics, and deletion workflows. Its package-manager niche is newer than traditional mail tools: it is not an email client, but a local archive substrate for search, personal analytics, and LLM/MCP access over a private message corpus.
