Enable iCloud on Mac and use the same Apple Account. On iPhone: search, calendar, bookmarks and offline access to synced records.

Local records by default; you opt into iCloud. English generation still uses the selected AI service. Filters low-value input and redacts high-confidence secrets. Preserves code, paths and URLs. Mac follow-up chats stay local and are neither synced nor exported. Delete cloud data separately while keeping Mac records.

Refinement replaces selected text; with no selection, it appends after the original. Requires Accessibility permission; also available in Services. Global shortcuts, pinning, opacity, light/dark themes, text size, launch at login and automatic updates. Read-only CLI for record export. On iPhone, copy record context or open ChatGPT, Claude or Gemini; you choose when to send.
