About

I'm Brian Casel, a full stack product builder who's gone all-in on AI-first development. Building with AI isn't just hypeโ€”it's leverage. It's transforming how we create software products, and I'm here to show you why mastering these techniques now will define who wins in the next decade. Each week, I share: - What's actually changing in our craft (not just what's trending) - Practical AI building techniques you can use today - Real lessons from shipping AI-powered products This isn't about chasing the latest models or buzzwords. It's about understanding how AI fundamentally changes what's possible for builders. If you're a developer, designer, or product builder who wants to stay ahead of the curve without getting lost in the noise, you're in the right place.

Video Description

Cursor 2.0 dropped last week, and unlike most recent AI updates, it's actually changed how I work. Two features in particular: Cursor's new Composer model that's 10-50x faster than any other coding model, and parallel agents that finally make running multiple autonomous builds practical. I'll show you Composer building and refactoring hundreds of files in 20 seconds, and how parallel agents let me build multiple features simultaneously without the Git worktree headaches. This isn't about hypeโ€”it's about observable shifts in how we can build when tools finally match our actual workflow. ๐Ÿ‘‡ **Your Builder Briefing (free)** https://buildermethods.com - Your free, 5-minute read to keep up with the latest tools & workflows for building with AI. ๐Ÿ‘‡ **Use Agent OS** (free open source): https://buildermethods.com/agent-os ๐Ÿ‘‡ **Join Builder Methods Pro** https://buildermethods.com/pro - The membership for professionals (and soon-to-be-pros) for building with AI.
