Mailbox Viewer

About

Mailbox Viewer turns a PST, mbox or Maildir mailbox into Parquet files, a word index and embeddings that can be hosted on any static host supporting HTTP range requests. A single front-end viewer then lets readers browse the emails in a Gmail-like interface, with no backend, by querying the data in the browser with DuckDB-WASM. It rebuilds conversations, supports Gmail-style search operators, searches inside PDF and Office attachments, offers in-browser semantic search, and gives every view its own URL. This makes public-records email releases easier to share and link to.
