I drive almost 2 hours a day, so I built an app that reads me articles in a voice made entirely on my iPhone. iPhone's Neural Engine is a breat. A 30-minute article in about 24 seconds. Wanted to share what I learned about local AI on your phone.

Hear it first, no install: a letter from 1863 warning that machines would outgrow us, read by the 82M-parameter voice that runs on my phone. hear.vois.audio/NhrF7Pr3uXxX…

Founders, what are you building right now? We want to make a video for it. Drop your website in the replies and tell us what you need, whether that's a founder intro, a demo, or the launch you keep pushing back. We'll pick a few to make with HeyGen MCP and post them here.

Last year at HeyGen, we launched a new feature every two weeks. Then it became two launches per week. Today, we shipped two launches in a single day. I want to talk about one of them, the Avatar Realtime launch. We put an AI avatar on Twitch and asked it to roast 24/7 People send GitHub repos in chat and it opens them, reviews the code, roasts bad design decisions, and navigates the browser by itself in real time Here: twitch.tv/heygendev Please watch it, it's pretty cool! I hope it's still online by the time you read this post. Great products matter, but enduring platforms are built on technical innovation, not just feature lists. Developers building on our APIs care about performance, reliability, scalability, and the research that powers it all. Those foundations are what create lasting value and enable entire ecosystems to grow. Technical Report - Avatar Realtime: heygen.com/research/avatar-i…

This is not a controversial take at all IMO. Everyone has different priorities and goals in life, but you cannot outcompete someone who operates this way. Also, working smart is something AI can help you greatly with - but working hard? That mentality and attitude? AI won't buy you that. Mandatory golf analogy: if you want to gain distance, you start with speed training without worrying about accuracy. Once you have the muscle, you work on accuracy.
1/ Controversial take: hard work is more important than smart work. It's a myth that we only have a few hours of good creative work per day. Train yourself to grind long hours first. You will surprise yourself. The work naturally become higher quality, less distracted.

Your agent already knew how to write. Now it knows how to show up. HeyGen Skills Describe your avatar or paste a photo. Your agent builds it, saves it for every future video, and engineers the prompt so your message actually lands. check the link below to get started 👇

We built our launch video in Claude Code using HyperFrames. Now it's yours. Open source, agent-native framework. HTML to MP4. $ npx skills add heygen-com/hyperframes RT + Comment "HyperFrames" to get the full source code of this launch video (must follow)

I have to admit the timing of my post on AI employee is poor. I've just seen 1,000 Snap ex-colleagues get laid off - all good and talented people. The idea of replacing a human workforce with AI agents sounds brutal. But I'll say this genuinely and unapologetically: there is a supply and demand imbalance for truly exceptional unicorns. The demand exists. The supply doesn't. That's the gap AI fills. It's also true that most of the workforce as we know it will look very different in the future. It's a hard reality to wrestle with. And reversing it doesn't feel possible.
Digital employee. No equity demands, no sprint complaints. Tempting.

This is 100% correct. I experience this 10 hours a day now
Peter Steinberger, creator of OpenClaw, on why AI agents still produce "slop" without human taste in the loop: "You can create code and run all night and then you have like the ultimate slop because what those agents don't really do yet is have taste." Peter is direct: raw capability without direction still produces mediocre output. "They are spiky smart and they're really good at things, but if you don't navigate them well, if you don't have a vision of what you're going to build, it's still going to be slop. If you don't ask the right questions, it's still going to be slop." Great AI-assisted work is defined by the human guiding it. @steipete describes his own creative process when starting a new project: "When I start a project, I have like this very rough idea what it could be. And as I play with it and feel it, my vision gets more clear. I try out things, some things don't work, and I evolve my idea into what it will become." Most people skip this part entirely, front-loading everything into a single prompt and wondering why the result feels hollow. "My next prompt depends on what I see and feel and think about the current state of the project." Each step informs the next. The work itself is the feedback loop. "But if you try to put everything into a spec up front, you miss this kind of human-machine loop. And then I don't know how something good can come out without having feelings in the loop — almost like taste." The agentic trap is what happens when you remove yourself from the process too early.

"Go to sleep, Ken. 😄" That was the first thing she said to me. My new hire. The one who lives in a Mac Mini. I'd been trying to find someone who could bridge AI builders and HeyGen. Half marketer, half builder. Deeply embedded. Our CEO asked how long it would take to hire this person. The honest answer: maybe never. So I built her instead. This is that story.
