I finally decided to give OpenClaw a try. I was just waiting for it to get a stable name 😀 If you’re in the X bubble, you probably got tired of OpenClaw posts by now. But if you’re someone who actually has a personal life and doesn’t scroll X every 5 minutes, here’s the deal. OpenClaw is an open-source personal AI assistant that you run on your own machine. You connect it to Telegram, WhatsApp, Slack, or whatever you use, and it becomes your always-on AI agent. It can browse the web, schedule...

There were times when a...

Back in May 2025, I was eating pierogi in Krakow. It was during my traditional trip to AppJS conf, and I was sitting across from Lukas, telling him how much I miss building and launching apps. The adrenaline that startups bring me. I remember saying out loud: "I wish I had more time to launch my own apps." And then I caught myself. Here's the thing - there's no such thing as "not having time" for something. We all have 24 hours a day. The same 24 hours that Elon has. The same 24 hours that...

Impression - They see your app in the store Product Page View - They click to learn more Download - They hit install Most developers obsess over features but ignore this funnel - and that’s a mistake.
