5 holes AI-built apps ship with. I built a free scan that checks yours. Paste your link. It reads what any visitor can see and flags leaked API keys, Supabase tables anyone can read, and private API data with no login. Under a minute, no signup. Link below.

We got Mark Zuckerberg vibe coding before GTA 6
Playing around with spaces in Muse lately -- tell Muse what you need and it builds it. I've made a BBQ game, an event tracker, and a home control dashboard. Excited to see what you build.

My first college hackathon project got roasted. 4th-year judges asked us to explain the logic. None of us could. The form had no back button. In my 3rd year, a US founder found my portfolio. The first of 10 companies to reach out. Free chapter on what changed: reply PLAYBOOK.

Here's what my AI agents shipped today. FixedLaunch: phone clicks now land on a mobile scan page FixedLaunch: new share card for the scan page Brio UI: dependency security fix passes checks, ready to merge Learned: ads can buy traffic, but nobody scans on a page that doesn't work on a phone.

What my AI agents shipped today FixedLaunch: checked the scan page on a phone, a phone-friendly step is next Swoopcut: Showcase mode films a startup's public pages Swoopcut: a full film in 17 minutes with the new Lite style Learned: "approved" is not "live". Check the live page after every fix.

We’re renaming our Max plans: Max 5x → Max Max 20x → Ultra Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do. We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed. Weekly limits remain unchanged.

On launch day, add a banner at the top of your site that links to your Product Hunt or Hacker News post. Visitors from elsewhere find the launch, and visitors from there know they landed in the right place. Take it down a day or two later.

Honest question for anyone using Muse Code every day: why do we all run it in a terminal? Is it habit, speed, or does the CLI just get features first?

My answer was to build a window for it. Helicon puts every Muse Code session in one sidebar, with edits as inline diffs and approvals in one place. Free and MIT, on Mac, Windows and Linux. Unofficial, not affiliated with Meta. helicon.sh/?utm_source=x&utm…

If agents buy software, your site has to work for them first. Vercel's Is Agentic scored my portfolio 75/100. Biggest miss: an agent asked for Markdown and got HTML. Fix: one URL, two formats, picked by the Accept header. Add an MCP server and JSON errors. Two evenings: 100.

I audited 35 outreach messages my agents wrote. 10 had false claims, like telling a founder they had no video when they had one. I deleted 5 public replies and sent private corrections. Now an agent checks the launch post, PH gallery and homepage before it claims anything.

The comeback is real
Introducing Gemini 4 Carbon, it's a big jump over Argon which we released just 2 weeks ago. Gemini 4 Carbon is SOTA on cyber, long horizon tasks, ranks #1 on Artificial Analysis V5, significantly improves on usability in domains like coding, and is more aligned.
