Archi

Years of Kindle highlights tend to sit stranded inside Amazon, hard to search and harder to act on. Archi pulls them down into a local SQLite library on your Mac with full-text search, so every passage you have ever flagged is finally one query away.

Sync runs on your machine without a server in the middle, and an optional one-click Notion export provisions Library and Passages databases so the same highlights can flow into your existing workflows. The app is free, open source, and ships with no telemetry.
