About NJL Design Lab
A personal workshop for consequential ideas.
NJL Design Lab is where I work through ideas about AI, money, software, and the systems that make a household more capable.
Why this exists
Build the tools the question deserves.
The site began with practical financial tools and expanded into a broader question: what should one person and one household learn, build, and protect as intelligent software becomes part of everyday life?
The projects are not separate from the writing. They are how the ideas get tested.
How AI is used here
AI helps with the work. It does not replace judgment.
AI assists with research, drafting, code, visual exploration, testing, memory retrieval, and repetitive operations. Important claims are checked, outputs are tested, and unfinished work is labeled unfinished.
What this site is not
Clear boundaries make the work more useful.
Not a forecast machine
This is not a promise that one AI, financial, or economic forecast will be correct.
Not professional advice
The material is educational and practical, not individualized financial, legal, medical, tax, or investment advice.
Not a success reel
Some experiments work, some are constrained, and some are paused. The record keeps the difference visible.
What readers can expect
Decisions, artifacts, sources, and honest limits.
Expect practical tools, clear assumptions, source links, documented constraints, and updates when the original plan changes. The goal is not to make uncertainty disappear. It is to make the next decision easier to see.
