At WWDC 2025, Apple introduces an AI-powered Shortcuts app
At WWDC 2025, Apple showed off a new AI-powered Shortcuts app. The company says Shortcuts can now tap into Apple Intelligence directly, and developers will be able to access Apple's on-device large language model (LLM). With Shortcuts, users will be able to access the AI models either on device or with Private Compute to generate responses that feed into the rest of their shortcut. For instance, a student could create a shortcut that uses AI to compare their audio transcription of their class lecture to their notes, then add key points they missed. They can also tap into ChatGPT to provide further responses that feed into their shortcut's input. Users will be able to tap into intelligent actions, which are a new type of shortcut that's enabled by Apple Intelligence. For instance, there are dedicated actions like those for summarizing text with AI (Apple Intelligence's Writing Tools) or creating images with Image Playground. Apple says the new features are available for testing starting Monday. The AI-assisted Shortcuts app follows the company's announcement last year of an AI-enhanced upgrade to its virtual assistant Siri, offering more personalized features and support. However, Apple then pushed back the launch, saying it would take longer to deliver than anticipated. At WWDC 2025, the company continued to make AI promises, including the introduction of an updated version of its Shortcuts app for scripting and automation. These AI changes could make Shortcuts easier to use for the less technically inclined, who have likely avoided using the app that has so far been more a part of a power user's toolkit. For example, popular shortcuts today can help you do things like make custom memes or GIFs, create meeting notes, track time spent on certain activities, create playlists, save PDFs, find out where a photo was taken, set location-based reminders, speed dial a friend, combine screenshots, shorten URLs, download files, save items to read later, and more. The update could also work as something of a stop-gap for Apple's delays to fully upgrade Siri with AI capabilities, as leveraging AI-assisted automation could make using the iPhone at least feel more efficient. (If you're willing to put in the work around shortcut creation, that is.) This article originally appeared on TechCrunch at Sign in to access your portfolio

PensionBee Survey Reveals Nearly Half of Americans Have Less Than One Year of Retirement Savings
New data reveals alarming saving gaps and costly behavioral patterns undermine retirement security across all generations NEW YORK, June 09, 2025 (GLOBE NEWSWIRE) -- Nearly one in three Americans (30%) couldn't survive more than six months on their retirement savings if they had to stop working tomorrow, while 42% have less than one year of savings total, according to new data from PensionBee's Q2 Happy Retirement Report. Just one in ten Americans believes they can live off their savings for 10 years or more. These findings reveal more than a retirement problem—they expose a survival crisis hiding in plain sight. With traditional pensions declining and Social Security facing potential cuts, Americans across all generations are more dependent on personal savings than ever before. Yet most are lacking basic financial resilience. 'Low saving levels among older workers are particularly troubling,' said Romi Savova, CEO of PensionBee. 'In an economy where companies are cutting costs and older workers often face the longest unemployment periods, inadequate savings isn't just about retirement, it's about basic survival. Too many people are one layoff away from being forced into a retirement they can't afford. With AI poised to reshape entire industries, this financial vulnerability becomes an existential threat for millions of American families." The Actions Behind the Numbers But here's what separates financial confidence from financial fantasy: specific, measurable actions. The survey reveals that confidence isn't built on hope—it's built on behavior. Among respondents who feel "very positive" about retirement, 61% have structured retirement plans, half with professional guidance, and 25% have consolidated multiple accounts. In stark contrast, just 9% of Americans who feel "very negative" about retirement have any structured retirement planning in place. Americans who felt 'very negative' about their retirement were also twice as likely (41%) to have delayed saving until age 30, compared to just 20% of those who reported a 'very positive' outlook. The data reveals the specific actions that separate confident savers from worried ones: starting early, maximizing employer benefits, consolidating old retirement accounts, and, when it makes sense, working with financial advisors. These aren't just nice-to-haves—they're the foundation of financial security in an uncertain economy. Retirement Preparedness Across Generations Gen Z: Building Financial Foundation Despite Early Challenges At 43%, Gen Z reports the second-highest retirement optimism, yet their behavior suggests financial vulnerability. Nearly one in five (19%) have already taken hardship withdrawals from retirement accounts—a concerning trend for a generation just starting their careers. However, they're also the most proactive: 25% plan to seek financial advice this year, and 29% are embracing online planning tools. Their challenge isn't awareness—it's building financial resilience while navigating an increasingly expensive economy. Millennials: Navigating Multiple Financial Priorities Millennials show clear signs of economic pressure from competing priorities. They report the lowest retirement confidence (41%) and are most likely to be managing student debt, aging parents, and childcare. Nearly one in four (22%) cash out their 401(k)s when changing jobs, compared to just 14% of Baby Boomers. Having entered the job market during the Great Recession, many developed financial habits that prioritize immediate needs over long-term wealth building. At 29%, they're most likely to delay starting retirement savings, missing crucial years of compound growth. Gen X: Managing Time Constraints and Competing Demands Gen X faces significant time pressure: 36% have less than one year of savings with fewer than 10 years until retirement age. Supporting both aging parents and college-bound children, they're working to build adequate retirement funds within a compressed timeframe. Further, only 23% consistently contribute enough to receive full employer matching funds, representing missed opportunities that could meaningfully improve their retirement outlook. Baby Boomers: Confident Outlook with Limited Savings Baby Boomers report the highest optimism (51%), though this confidence may not fully align with current retirement trends showing later retirement ages and continued reliance on part-time work. Despite being around retirement age, nearly half (49%) of Baby Boomers reported having five years or less of savings. This generation's optimism reflects a different economic era—one with pensions, affordable healthcare, and more predictable career paths. What Comes Next Despite these challenges, the survey reveals reason for optimism: half of Americans plan to increase contributions this year, suggesting growing awareness of the problem. 41% of Americans reported a positive retirement outlook in Q2—down over 10% from Q1's survey. This declining confidence seems to reflect not only the market volatility but perhaps a growing awareness that individual effort alone cannot solve a systemic problem. "The widespread lack of retirement preparedness we're seeing isn't something workers can solve alone," added Savova. "Employers have a critical role beyond just offering a 401(k). When workers are cashing out accounts during job changes and missing employer matches, that's a clear signal that current benefit structures aren't working. We need to reform our system and take active steps: automatic enrollment, better education, and support systems that help departing employees preserve their savings rather than lose them.'
