Quiet Engine Co.About
Quiet Engine Co. is a one-person digital-products shop run by Luis Zuniga in Texas. The idea is simple: small, dependable tools that handle the boring parts of running a home or a small business.
What we make
Practical spreadsheets, printable planners and PDFs, AI agent skills in the open SKILL.md format, and n8n workflow templates. Each one is a file you download and keep. No subscriptions, no accounts to connect.
How it's made
We build with AI assistance and then test. Spreadsheet formulas are recalculated in LibreOffice and checked after a Google Sheets import. Agent-skill scripts pass automated tests on Python 3.8 and 3.13. n8n workflows are imported and run on a local test instance with mock data. Product pages list what was tested and what wasn't, and the limits of each product.
What we won't do
- Promise income, results or savings.
- Post fake reviews or testimonials.
- Sell or share your email address.
Our tax-related products are organizers and rough estimators, not tax advice. Food-safety numbers in the holiday planners come from USDA FSIS guidance, and you should always check 165°F with a food thermometer.
