Perplexity Becomes a Finance App, Amazon Reveals Its AI Revenue, Oxford’s Heart Failure Breakthrough

Today we’re covering the biggest AI stories of April 10th, 2026. Perplexity launched a Plaid integration that connects its Computer agent directly to your bank accounts, credit cards, and loans — turning it into a full personal finance hub that can build budgets, track net worth, and create debt payoff plans on demand, putting it in direct competition with Mint, TurboTax, and every other finance app on your phone. Amazon CEO Andy Jassy published his annual shareholder letter with the company’s first-ever AI revenue figures — AWS’s AI arm crossed $15 billion in annualized revenue, and its custom chips are doing $20 billion a year with customers reportedly trying to buy the entire supply. Plus, Oxford researchers unveiled an AI that detects invisible changes in heart fat from routine CT scans, predicting heart failure up to five years out with 86% accuracy — and a community workflow from a job candidate who used AI to do mock interview prep, including researching all five board members before the final round.
