How we work
Research
Every site starts from a real, finite dataset and primary sources — state education departments, published standards, manufacturer specifications.
Verify
Every fact traces to its source. If we can't verify something, we leave it out. No padding, ever.
Publish
Fast, quiet pages with the answer at the top. Few ads, clearly separated. The kind of page you'd bookmark.
Maintain
Sites are kept, not churned. Data gets re-verified, dated, and corrected in the open.
