GitHub CEO on the AI Coding Arms Race: One Agent, 150M+ Devs

If you had millions of people using a product you spent years building, would you kill it?That’s exactly what The Browser Company did with Arc.The internet backlash was intense, but cofounders Josh Miller and Hursh Agrawal saw that AI was about to make the web something you talk to, not just click into. The best home for that assistant was the thing that's already between you and the internet—the browser. And they realized they couldn’t just duct-tape it on to Arc.One year of heads-down work later, the team launched Dia in beta, and people are raving about it. Dia is a sleek, fast, browser with AI at its core—it gets better with every tab you open, becoming more and more helpful with time. And even though it’s still early, Josh and Hursh’s big pivot looks like one for the ages.This week on AI & I, Josh and Hursh joined me for their first full-length podcast about their pivot from Arc to Dia. We talk through their decision-making process, the very public backlash the company faced, and the grit it took to stay the course. If you found this episode interesting, please like, subscribe, comment, and share! Want even more?Sign up for Every to unlock our ultimate guide to prompting ChatGPT here: https://every.ck.page/ultimate-guide-to-prompting-chatgpt.

You don’t need to handle your inbox anymore. It’s Cora’s job now. Cora is the AI chief of staff we built for your email at Every. It’s been in private beta for the last 6 months and currently manages email for 2,500 beta users—and today we’re making it available for anyone to use. Start your free 7-day trial by going to: https://cora.computer/Cora is the $150K executive assistant that costs $15/month. Or $20/month if you want an Every subscription, too. This is what that actually means:Cora understands what’s important to you, screens your inbox, and only lets the most relevant emails through. The rest of your emails are summarized in a beautifully designed brief that’s sent to you twice a day.If it has enough context, Cora drafts replies for you in your voice.You can talk to Cora like you would your chief of staff—you can give it special instructions on how you want certain emails handled, ask it to summarize things, and even give you an opinion on complex decisions.In this episode of AI & I, I sat down with the team behind Cora—⁠Brandon Gell⁠, head of the product studio; ⁠Kieran Klaassen⁠, Cora’s general manager; and ⁠Nityesh Agarwal⁠, engineer at Cora—for a closer look at how it all came together. We talk about:The story of the first time Brandon, Kieran, and I used Cora, while sipping wine at the Every retreat in Nice. The evolution of Cora’s categorization system, from a 4-hour vibe-coded prototype to a multi-faceted product with thousands of happy users.The features on Cora’s roadmap we’re most excited about: a unified brief across different email accounts, an iOS app, and an even more powerful assistant.This is a must-watch if you’re curious about what it feels like to give Cora your inbox, and take back your life.

Joe Hudson is a coach who works with the executives building AGI at OpenAI. From inside OpenAI, he witnesses the full spectrum of human emotion that comes with bringing something new into the world—the exhilaration, the terror, the weight of it all. He feels these emotions, too: He believes AI will eventually replace what he does as a coach.But instead of fixating on that fear, Hudson is asking a deeper question: Who is he becoming in the meantime? He believes that moments like this—when we can feel the ground quiver—can be powerful catalysts for transformation, but only if we’re willing to face the uncertainty they bring.In this episode of AI & I, Dan Shipper sits down with Hudson to talk about how he’s answering that question. They get into what happens when the thing you’ve built your life around might disappear, how to find who you are beneath your professional identity, and why Hudson believes intention is the key to growing with AI.If you found this episode interesting, please like, subscribe, comment, and share! Want even more?Sign up for Every to unlock our ultimate guide to prompting ChatGPT here: https://every.ck.page/ultimate-guide-to-prompting-chatgpt.

If you’re using AI to just write code, you’re missing out.Two engineers at Every shipped six features, five bug fixes, and three infrastructure updates in one week—and they did it by designing workflows with AI agents, where each task makes the next one easier, faster, and more reliable.In this episode of AI & I, Dan Shipper interviewed the pair—Kieran Klaassen, general manager of Cora, our inbox management tool, and Cora engineer Nityesh Agarwal—about how they’re compounding their engineering with AI. They walk Dan through their workflow in Anthropic’s agentic coding tool, Claude Code, and the mental models they’ve developed for making AI agents truly useful. Kieran, our resident AI-agent aficionado, also ranked all the AI coding assistants he’s used.If you found this episode interesting, please like, subscribe, comment, and share! Want even more?Sign up for Every to unlock our ultimate guide to prompting ChatGPT here: https://every.ck.page/ultimate-guide-to-prompting-chatgpt.

OCD treatment changed my life—but it took me a decade of chasing down wrong answers to be diagnosed. In the rush to create scalable treatments, disorders like depression and OCD are squeezed into diagnostic checklists—from which the complexity of the human mind invariably leaks out. The field of psychiatry is broken, and I spoke to someone on the inside about how AI can help fix it .Awais Aftab has been questioning psychiatry’s rigid categories from inside the field. He’s a clinical assistant professor at Case Western Reserve University, editor of Conversations in Critical Psychiatry—an Oxford University Press volume that tackles philosophical and critical perspectives in psychiatry—and author of the Substack newsletter Psychiatry at the Margins.
