Two operating systems I built for myself: Personal OS to run my life, and SaaS Startup OS to run every product I'm building. The tooling I wished existed.
Notion, Linear, Trello, ClickUp. I tried all of them. None of them fit the way I actually work, which is: a lot of parallel projects, all at different stages, all with different rules, and a need to know at a glance what the next thing to ship is. So I stopped trying to bend other people's tools and built my own.
A project management layer for every SaaS I'm building. Each product moves through a fixed 12-stage pipeline: Ideation → Validation → Architecture → MVP → UI/UX → Development → Testing → Launch → Growth → Scaling. The OS knows which stage each project is in, what the next unchecked task is, and writes a fresh CLAUDE.md context file into the project folder so any AI assistant I use already knows where the project is and what to work on.
That context file is what you saw at the top of the Outpaint.AI page. It was written by this tool.
The other half is a calendar, planner, and habit tracker tuned to how I actually work and train. Less feature-rich than the SaaS OS by design. It's there to make me decisive in the morning and accountable at night.
A tool you build for yourself is the most honest product spec you'll ever write. Every feature has one user with no patience for fluff. If a screen takes more than two seconds to give me what I want, I rip it out. It's the cleanest UX exercise I've done.
