CAUTION

Publisher claims: "Let ChatGPT, Claude, Cursor & any MCP client actually use your Mac or Windows PC — read & reply to email, manage your calendar, text over iMessage, find files, work with Teams, Slack, Notion & Office. Runs locally, no API keys." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
