Who gets to spend when an AI agent shops?
Amex and JPMorgan drew different lines for agents and money. Plus Gemini 4 Argon, private Android apps, Character.AI and a cheaper way to filter news.

American Express proposed a way to record what a customer approved before an AI agent makes a purchase. JPMorgan took a more cautious line on agents accessing customer accounts. The two announcements made the same question concrete: who decides what the agent can do with your money?
Amex puts approval before payment
Amex's proposed framework records the customer's instructions and asks them to approve the purchase intent before the agent acts. On JPMorgan's earnings call, its CFO said the bank was blocking outside agents where possible when they used customers' shared credentials to access accounts or move money.
