Email, calendars, forms and paperwork · 213 ideasHis wife asked her renamed, recolored the AI to review her email inbox

Turn my bookshelf photo into our building's borrow list

Security-review a suspicious email that passed every check
A Tesla engineer got an email that passed SPF, DKIM and DMARC and showed a verified check, but felt off, so he had his AI review it without clicking anything; the bot found a hidden phishing link, explained why the standard checks had passed, and wrote a report to xAI with a proposed fix.

The AI built a label and filter system for a crowded inbox
The creator set up the AI on its own computer, connected Gmail, and used AI to write the bot's voice and brief before testing it on a throwaway inbox of 745 threads with zero labels. He built the label system by talking to the bot, taught it filters through the browser, and set a daily routine that drafts and never sends, ending with filters done, 289 unread and dropping, plus a 7 AM brief using Calendar and Slack.
