Armchair quarterbacking someone else's business is not helpful.
You can't possibly have more actionable information than the founder does--primarily their motivations and priorities.

2025 was like the first season of a sci-fi show: Just there to orient us in this weird new world.
2026 is season 2, when the story really gets going.

I use plan mode on most things.
but I plan bigger picture in claude and carry things over... like moving from building the app to writing copy for the marketing site to planning strategy, etc. That stuff needs to know the latest from the app build.

This was my first use of Design OS on a real, shipped app.
Took about 7 work days start-finish. Smoothest design- to-build process I've done yet.
Full walkthrough of the process is available inside Builder Methods Pro.

Reading every response is impossible. Missing important ones is expensive.
So I built InboxSummaries: It reads my incoming surveys, etc. and surfaces insights, trends and opportunities I'd otherwise miss.
Using it daily now. Should I open it up?

Really want to see a smoother hand-off between Claude Code and Claude projects. I constantly move between the two (Claude for ideating and planning and Claude Code for building).

I find Opus 4.5 is excellent both in Claude Code and in Cursor's Agent mode. I use both regularly.
Claude Code for big, autonomous tasks.
Cursor agent when I'm working with agent more collaboratively through a problem or design tweaks.
