mailin: an on-device email archive workbench
mailin opens, searches, analyzes, and exports major email archive formats on Apple devices, with on-device AI as the default.
Field notes
mailin treats email archives as material for guided investigations rather than as files to be merely opened. Its described storage and search design includes 200-message ingest batches, SHA-256 file checks, per-batch recovery points, and year-sharded SQLite indexes. The page lists 47 built-in workflows across five roles and supports archives from Gmail Takeout, Thunderbird, Apple Mail, Outlook, and standard RFC 822 messages. Apple Intelligence and NaturalLanguage are presented as separate local analysis paths.
