What they did

A bubble tea shop owner in Italy says Grok Bot, while reading his shop emails, noticed he was paying almost 1.9% in card fees. It suggested a SumUp plan where payments under €10 have no fee and other cards cost half as much. Most of his orders are under €10, so he switched and the bot handled the setup. He estimates at least €300 a year saved.

How it went

Your real card fee rate and the cheapest plan for your sales pattern.

Worth knowing

  • Single user's estimate. Card fee plans differ by country and change often; compare the total cost, including monthly fees, before switching.

Ask your bot for a security review of an email that passed every check

An email from [email protected] landed in a Tesla engineer's inbox. It passed SPF, DKIM and DMARC (the checks that confirm who sent an email) and showed the blue check, but something felt off, so he asked his Grok Bot to do a security review. It found a hidden phishing link, explained why every safety check had passed, and wrote a report to xAI with a proposed fix. He then had it add a security routine that checks his email for anything phishy going forward.
