Solo dev adds agent-edited contacts to address book app Sealed, with approval gates and undo
SeanOliver · x · 2026-11-07
Solo developer Sean Oliver describes a new capability in his address book app Sealed: an AI agent can edit contacts.
- Friends fill in their own addresses via a link; agent edits save immediately, each with an Undo.
- Sensitive changes (email updates, deletions) require explicit human approval.
- Code review kept surfacing edge cases around bulk edits and an Undo-all button, so both were cut.
Sealed is an invite-only beta for holiday cards: send one link, everyone fills in their details, you get a print-ready address book.
