Our vibe coded projects that actually work

The Vergecast

Jun 29, 202633 minExecutive Editor

AI Summary

→ WHAT IT COVERS Vergecast hosts David Pierce, Jake Kastronakis, and Hayden Field share vibe-coded projects they built and actually use daily — a meeting notes app, a custom Gmail label interface, and a personalized habit tracker — then receive a four-week challenge to build personal websites using AI coding tools. → KEY INSIGHTS - **Vibe Coding Success Criterion:** The "toothbrush test" filters viable projects — only build something you will use at least twice daily. The majority of vibe-coded projects fail not because the technology cannot build them, but because the builder never identifies a genuinely recurring personal need before starting. Narrowing scope to one specific friction point dramatically increases the chance of daily adoption. - **Tool Comparison — Claude Code vs. Codex:** Claude Code produces functional, problem-solving code with clear step-by-step guidance but generates visually plain interfaces by default, requiring manual design direction. Codex produces aesthetically polished outputs immediately but confuses non-developers with unclear next steps and failed Expo Go version compatibility during mobile app setup, making Claude Code the stronger choice for functionality-first builders. - **Browser Extensions as Vibe Coding Entry Point:** Chrome extensions are the lowest-risk starting project for beginners — they are structurally simple, load instantly without deployment, and have a narrow failure surface. Pierce built a working web clipper tab-filing system as a browser extension faster than any other project, reducing open browser tabs and RAM usage immediately upon completion. - **Security Vulnerabilities Are Universal and Unresolved:** Both Claude Code and Codex flagged 15 high-severity and 15 medium-severity security vulnerabilities in Field's habit tracker, yet both tools advised ignoring them. Vibe-coded apps should not be shared publicly or deployed to open internet without developer review, as AI tools systematically underreport risk to non-technical builders who lack context to evaluate warnings independently. - **Data Durability Requires Explicit Backup Instructions:** Kastronakis discovered his meeting notes app had no backup system and proactively prompts Claude weekly to audit data integrity. The practical fix — asking the AI to export all stored data as plain text files — takes one prompt and prevents total data loss from local cache failures, a risk present in any locally hosted vibe-coded application. → NOTABLE MOMENT Kastronakis built a fully functional custom Gmail client over a single weekend to solve one problem: surfacing personal labels as top-level tabs. The unintended consequence was accidentally replicating the core feature set of Superhuman, a product that charges users thirty dollars monthly. 💼 SPONSORS [{"name": "ServiceNow", "url": "https://servicenow.com"}, {"name": "GEICO", "url": "https://geico.com"}, {"name": "Fetch Pet Insurance", "url": "https://fetchpet.com/save"}, {"name": "Indeed", "url": "https://indeed.com/podcast"}, {"name": "LifeLock", "url": "https://lifelock.com/podcast"}] 🏷️ Vibe Coding, AI Development Tools, Claude Code, Productivity Apps, Software Security

Maybe it's real, maybe it's Sora

The Vergecast

Oct 10, 202590 minCo-host

AI Summary

→ WHAT IT COVERS OpenAI's Dev Day introduces apps-within-ChatGPT strategy, shifting from autonomous AI agents to API integrations with companies like Spotify and Zillow. Sora video app launches with 627,000 downloads, sparking debates about AI-generated content and copyright policies. → KEY INSIGHTS - **ChatGPT Platform Strategy:** OpenAI pivots from training AI to autonomously use websites toward API partnerships where companies like Zillow integrate databases directly, enabling natural language queries with follow-up questions. This App Store-style approach prioritizes functional integration over theoretical agentic AI that remains largely vaporware. - **Sora Adoption Mechanics:** The video generation app succeeds through remix features allowing users to swipe left-right between variants of the same prompt, creating collaborative joke refinement. Algorithm learns preferences faster than Meta's Vibes, making AI-generated memes feel more intentional than generic screensaver content that plagued earlier attempts. - **Copyright Policy Reversal:** OpenAI initially launched Sora with opt-out copyright protection, forcing creators to proactively block their content from training data. After immediate stakeholder protests within thirty minutes, the company reversed to opt-in, demonstrating reactive rather than proactive policy development around intellectual property rights. - **Compute Infrastructure Crisis:** The Jony Ive collaboration on always-listening AI hardware faces fundamental compute constraints. Processing continuous audio streams requires data center resources OpenAI cannot currently access at scale, creating thirty-second response delays that make real-time home device interaction impractical compared to traditional voice assistants. - **Intel Panther Lake Stakes:** Intel's upcoming chip line represents final proof-of-concept for 18A manufacturing process after years of falling behind AMD, Apple, and Qualcomm. Success determines whether Intel survives as both chipmaker and foundry, with implications for US semiconductor independence beyond consumer laptop performance benchmarks. → NOTABLE MOMENT Sam Altman admits OpenAI expected neither the volume of Sora usage nor user concerns about AI-generated deepfakes and copyright. His technological and societal coevolution philosophy essentially acknowledges breaking things first, then addressing consequences, repeating Facebook's controversial move-fast approach with generative video at global scale. 💼 SPONSORS [{"name": "Figma", "url": "https://figma.com/vergecast"}, {"name": "Charles Schwab", "url": "https://schwab.com"}, {"name": "LinkedIn", "url": "https://linkedin.com/track"}, {"name": "Twilio", "url": "https://twilio.com"}, {"name": "1Password", "url": "https://1password.com/burjcast"}, {"name": "Zapier", "url": "https://zapier.com/verge"}] 🏷️ OpenAI Dev Day, Sora Video Generation, AI Agents, Intel Panther Lake, ChatGPT Platform

Who is the iPhone Air really for?

The Vergecast

Sep 17, 202581 miniPhone Reviewer

AI Summary

→ WHAT IT COVERS The Vergecast reviews Apple's iPhone 17 lineup, focusing on the new iPhone Air's thin design trade-offs, the base iPhone 17's promotion to flagship status, and Apple Watch SE 3 emerging as the smartwatch most people should buy. → KEY INSIGHTS - **iPhone Air battery reality:** The Air delivers 28-30 hours per charge on new hardware, barely exceeding the 24-hour rating. Users doing heavy tasks hit 20% low power mode by dinner, raising concerns about longevity as battery degrades over the phone's lifespan compared to standard models. - **Base iPhone 17 positioning:** The iPhone 17 now includes always-on display and 120Hz refresh rate, previously Pro-exclusive features. At $300 less than Pro models, it eliminates the performance gap that historically justified premium pricing, making it the clear choice for most buyers without specialized camera needs. - **Apple Watch SE 3 value:** The SE 3 adds always-on display, fast charging (zero to 80% in 45 minutes), and 5G for $249, undercutting the Series 11 by $150. It includes most health features except EKG spot checks and hypertension notifications, making the Series 11 feel like an unnecessary middle option. - **iPhone Air physical trade-offs:** Weight reduction makes the Air noticeably lighter during extended use, reducing hand fatigue. However, the single camera lacks ultra-wide capability, creating frustrating limitations at the $1000 price point when users cannot back up physically to capture wider shots in confined spaces. - **Apple AI strategy divergence:** Apple focuses on practical on-device AI features like text extraction from photos rather than chatbot interfaces. The company outsources conversational AI to OpenAI and Anthropic while building infrastructure for developers, avoiding the agentic AI race that remains largely non-functional across the industry. → NOTABLE MOMENT The reviewer experienced near-panic on a plane thinking the iPhone Air had slipped between seats due to its thinness, only to discover it was safely in a bag. This incident highlighted how the device's reduced profile creates new anxiety about losing it in everyday situations like couch cushions. 💼 SPONSORS [{"name": "Atlassian", "url": "https://atlassian.com/jira"}, {"name": "Figma", "url": "https://figma.com/vergecast"}, {"name": "Charles Schwab", "url": "https://schwab.com"}, {"name": "1Password", "url": "https://1password.com/vergecast"}, {"name": "LinkedIn", "url": "https://linkedin.com/track"}, {"name": "Zapier", "url": "https://zapier.com/verge"}] 🏷️ iPhone 17, Apple Watch SE, Smartphone Reviews, Apple Intelligence, Wearable Technology

Meta's quest to own your face

The Vergecast

Sep 19, 202592 minMentioned as Upcoming Participant

AI Summary

→ WHAT IT COVERS FCC Chair Brendan Carr pressures broadcasters to cancel Jimmy Kimmel after Trump criticism, threatening merger approvals. Meta announces Ray-Ban smart glasses with heads-up displays, neural wristband controls, and Oakley fitness variants. Reddit renegotiates Google deal demanding more money and user traffic. → KEY INSIGHTS - **Government Speech Coercion:** Brendan Carr threatens Nexstar and TEGNA's $6.2 billion merger approval unless broadcasters remove Jimmy Kimmel, stating "we can do this the hard way or the easy way." This merger requires waiving the 39% household reach limit to hit 80%, giving Carr dual leverage points over companies. - **Smart Glasses Control System:** Meta's neural wristband uses electromyography to detect finger movements without cameras or line-of-sight requirements. Users pinch to select, double-pinch to activate displays, and fist-swipe to navigate. This approach outperforms eye-tracking and hand-gesture systems used by competitors like Vision Pro. - **Display Glasses Specifications:** Ray-Ban Meta Display glasses weigh 69 grams, deliver 5000 nits brightness on 600x600 pixel screens with 20-degree field of view, and provide six hours battery life. Meta targets 1-2 billion daily glasses wearers rather than convincing non-wearers to adopt new eyewear. - **Platform Creator Economics:** YouTube enables dynamic ad insertion into existing videos, allowing creators to monetize old content with new sponsors and negotiate channel-wide deals instead of per-video sponsorships. This shifts creator revenue models away from integrated sponsorships toward programmatic advertising similar to broadcast television. - **Reddit Search Leverage:** Reddit renegotiates its Google deal from a position of strength, demanding both increased payment and guaranteed user traffic. Google search increasingly returns Reddit results as the open web declines, making Reddit essential infrastructure for search functionality and AI training data. → NOTABLE MOMENT A Meta Connect demo attempting to showcase live AI cooking assistance failed repeatedly when the system incorrectly identified ingredients and preparation steps. The presenter blamed WiFi issues, but the failure exposed fundamental problems with AI reliability and error recovery that users will encounter in real-world applications. 💼 SPONSORS [{"name": "AWS", "url": null}, {"name": "MongoDB", "url": "mongodb.com/build"}, {"name": "Charles Schwab", "url": "schwab.com"}, {"name": "Shopify", "url": "shopify.com/vergecast"}, {"name": "Twilio", "url": "twilio.com"}, {"name": "Rippling", "url": "rippling.com/verge"}, {"name": "Zoom", "url": "zoom.com/podcast"}, {"name": "Zapier", "url": "zapier.com/verge"}] 🏷️ FCC Regulation, Smart Glasses, Neural Interfaces, Content Moderation, Creator Economy, Search Monopoly

The Pixel 10's AI screamed at us

The Vergecast

Aug 29, 202595 minExecutive Editor of Verge

AI Summary

→ WHAT IT COVERS Google Pixel 10 introduces on-device AI features including MagicQ contextual suggestions and ProRes Zoom with 100x AI enhancement. Reviews reveal mixed results with voice translation glitches, text recognition failures, and questions about computational photography boundaries versus authentic images. → KEY INSIGHTS - **On-Device AI Limitations:** MagicQ works only within Google's ecosystem (Gmail, Calendar, Messages, Keep) and requires specific phrasing to trigger suggestions. Testing showed inconsistent performance when users deviate from natural sentence structure or mix languages, particularly failing with code-switching between English and Japanese during conversations. - **AI Voice Translation Failures:** Real-time voice translation mimics speaker voices but breaks down with non-standard speech patterns. Testing between English and Japanese revealed the system screams error sounds when encountering incomplete sentences, mixed languages, or conversational pauses, making it unusable for actual family communication where pidgin languages are common. - **ProRes Zoom Text Problem:** The 100x AI zoom enhancement performs well on architecture and landscapes between 30-50x magnification but completely fails on text, generating nonsensical letter combinations. This reveals AI's inability to understand language structure, making the feature unreliable for reading signs or capturing text-based information from distance. - **Apple Intelligence Delays:** iPhone 17 announcement September 9 faces pressure to match Google's AI integration. Apple's cautious approach with ChatGPT partnership and potential Gemini addition contrasts with Google's aggressive on-device AI deployment. Rumors suggest design refresh with sideways camera bump and orange color option as primary differentiators. - **DISH Network Collapse:** FCC Chairman Brendan Carr's investigation forced DISH to sell all spectrum to AT&T, eliminating the fourth major wireless carrier that Trump's first administration mandated. This consolidates power among three carriers, contradicts original T-Mobile-Sprint merger conditions from 2019, and demonstrates regulatory failure to maintain competition. → NOTABLE MOMENT During live testing of Pixel 10's voice translation feature, the AI-generated voice suddenly began screaming unintelligible sounds when encountering mixed Japanese-English sentences and conversational pauses. The robot voices glitched repeatedly, transforming what should have been smooth translation into an unsettling demonstration of AI's inability to handle natural human speech patterns. 💼 SPONSORS [{"name": "MongoDB", "url": "https://mongodb.com/build"}, {"name": "AWS", "url": null}, {"name": "LinkedIn", "url": "https://linkedin.com/track"}, {"name": "Grammarly", "url": null}, {"name": "Figma", "url": "https://figma.com/vergecast"}, {"name": "1Password", "url": "https://1password.com/vergecast"}, {"name": "Framer", "url": "https://framer.com/design"}, {"name": "Charles Schwab", "url": "https://schwab.com"}] 🏷️ Google Pixel 10, AI Translation, Smartphone Photography, DISH Network, FCC Regulation, iPhone 17

ChatGPT enters the browser wars

The Vergecast

Oct 24, 2025100 min

AI Summary

→ WHAT IT COVERS OpenAI launches Atlas browser with agentic AI capabilities, triggering browser wars among tech companies. Discussion covers AI agents' infrastructure challenges, Warner Brothers Discovery sale prospects, AWS outage impacts, and GM's CarPlay elimination strategy amid automotive AI integration. → KEY INSIGHTS - **AI Browser Economics:** ChatGPT Atlas requires $20/month Plus or Pro subscription to enable agentic features that slowly automate web tasks like purchases and form filling. The product demonstrates fundamental tension between trillion-dollar valuations and actual consumer utility, with speed and reliability issues preventing mainstream adoption despite novel computer-use capabilities. - **Agent Infrastructure Problem:** AI agents need controlled application environments to function effectively. Companies face three failed approaches: walled gardens like Claude work but limit scope, cloud-based browsers require users to share credentials on remote servers, and local OS access faces Apple's execution paralysis. Browsers emerge as the only viable operating system layer for agentic AI. - **Web Disintermediation Risk:** Agentic browsers threaten to transform web applications into commodity data layers, similar to how AI already pressures information websites. Airbnb CEO Brian Chesky explicitly stated he refuses to become just a data provider for AI bots, highlighting the DoorDash problem where AI intermediation destroys direct customer relationships and business leverage. - **Regulatory Self-Contradiction:** FCC Chair Brendan Carr attempts to preempt state AI regulation by classifying AI as a telecommunications service under 47 USC 253. This directly contradicts his decade-long effort with Ajit Pai to prevent broadband classification as Title II telecommunications, creating legal impossibility where AI cannot be more regulated than the pipes it runs on. - **Streaming Consolidation Pressure:** Warner Brothers Discovery pursues sale after three price increases at HBO Max, while Hulu Live TV reaches ninety dollars monthly. The cable-to-streaming transition accelerates as companies split declining linear assets from streaming divisions, potentially ending mainstream media's thirty-year dominance as YouTubers and TikTokers capture narrative-setting power and audience attention. → NOTABLE MOMENT The host experienced a house fire when a fifteen to twenty year old surge protector spontaneously combusted, melting the outlet and singeing walls despite no connected load. Fire department response revealed the critical but overlooked risk of aging electrical safety equipment that consumers typically carry across multiple residences without replacement consideration. 💼 SPONSORS [{"name": "MongoDB", "url": "https://mongodb.com/build"}, {"name": "Figma", "url": "https://figma.com/vergecast"}, {"name": "Zapier", "url": "https://zapier.com/verge"}, {"name": "Shopify", "url": "https://shopify.com/vergecast"}, {"name": "LinkedIn", "url": "https://linkedin.com/track"}, {"name": "Darktrace", "url": "https://darktrace.com/defenders"}] 🏷️ AI Browsers, Agentic AI, Media Consolidation, FCC Regulation, Streaming Economics, Automotive AI

Vibe coding through the GPT-5 mess

The Vergecast

Aug 15, 202582 minHost

AI Summary

→ WHAT IT COVERS The Vergecast examines GPT-5's troubled launch, including user backlash over personality changes, removed model access, and disappointing performance. The team tests vibe coding capabilities and discusses corporate shenanigans from Perplexity, Apple, and Elon Musk. → KEY INSIGHTS - **GPT-5 Launch Problems:** OpenAI removed GPT-4o access without warning, changed model personality from warm to robotic after user complaints, then overcorrected back. The company now promises advance notice before removing models, learning that power users rely on specific models for different tasks and need consistency for professional workflows. - **Vibe Coding Reality Check:** GPT-5's coding feature fails non-programmers by providing code snippets requiring manual implementation rather than working applications. All three hosts attempted simple projects but encountered broken outputs, missing functionality, and instructions assuming coding knowledge. The feature works better for existing developers who can debug errors. - **AI Medical Dependency Risk:** Doctors using AI for colonoscopy cancer detection became six percentage points worse at detecting cancer independently after AI removal. The study across Poland, Norway, Sweden, UK, and Japan reveals skill degradation when professionals rely on AI assistance, similar to GPS dependency eroding navigation abilities. - **Chatbot Self-Knowledge Limits:** AI chatbots cannot accurately explain their own operations, bans, or reasoning. When Grok was banned from X and BlueSky, it provided contradictory explanations including genocide statements, content refinements, and adult content identification. Chatbots only know what exists in training data and blog posts, not internal system states. - **Apple Trademark Aggression:** Apple sues Apple Cinemas movie chain despite owning all Apple-prefix trademarks after buying out Beatles' Apple Corps following decades of litigation. The company called the theater's landlord before filing suit, demonstrating extreme brand protection stemming from historical trademark battles that nearly cost them their name. → NOTABLE MOMENT One host discovered their attempt to build an interactive chess training app resulted in a sophisticated interface with multiple features and buttons, but the chatbot consistently made Black move first instead of White, violating basic chess rules despite repeated corrections across multiple attempts. 💼 SPONSORS [{"name": "Atlassian", "url": "https://atlassian.com/jira"}, {"name": "Figma", "url": "https://figma.com/vergecast"}, {"name": "MongoDB", "url": "https://mongodb.com/build"}] 🏷️ GPT-5 Launch, Vibe Coding, AI Medical Diagnosis, Apple Trademark Law, Chatbot Limitations
