Build a local-first bookmark vault with dependable import and export, automatic versioned backups, tag preservation, exact and whole-word search, duplicate detection, and bulk editing. Keep data portability free and charge a one-time license or subscription for advanced cleanup, cross-browser synchronization, encrypted backup, and collection repair. Start with a browser extension and desktop companion that operate on standard bookmark files without replacing the new-tab page.

Recent reviews show that established extensions are placing basic portability behind paywalls while updates continue to damage tags and familiar workflows. This creates an opening for a trust-centered product whose core promise is data ownership and reversible migration.
