What’s new.

Workspace

One folder, one scan

Repeated and stale folder bookmarks now collapse onto the same resolved folder. Reopening a workspace no longer multiplies its sidebar roots and recursive scans.

Native core

Swift 6 throughout

The app and tests now use Swift 6 with complete concurrency checking and explicit ownership of shared state. Pensieve still runs on macOS 15 or newer.

Known limits

AI and dictation are still evolving

Dictation has an unresolved recording issue. Large AI rewrites can exceed provider limits, and custom rewrite instructions still use a single-line field. These workflows are not qualified for this release.
