Editorial policy
Useful first. Verifiable where it matters.
SolveKit is a product library, not an article farm. This is the standard used to decide what gets indexed, what needs another review, and how corrections are handled.
Last updated July 24, 2026
01
A tool must complete a real task
We add a page only when it produces a useful result, transformation, file, validation, or decision path. Page count is not a reason to publish.
02
Inputs and assumptions must be visible
Reviewed calculators explain what each input means, identify important exclusions, and show formulas or processing steps where that helps someone verify the result.
03
External facts need primary sources
Fees, rates, rules, standards, and technical behavior are checked against the provider or standards body whenever a primary source exists. Review dates are shown on priority pages.
04
Commercial relationships do not alter results
Advertising and affiliate relationships do not change formulas, default values, rankings, related-tool selections, or whether a correction is published.
Testing and search eligibility
Core calculation engines have automated regression cases. Browser-based file tools are checked with representative inputs and failure states. A working page can remain available while carrying a noindex instruction if its sourcing, edge cases, or explanatory material do not yet meet the standard for search.
Translations
A translated URL is published only when the complete task page, interface, metadata, and important warnings have been reviewed in that language. The Spanish directory exposes English-only tools with an EN label instead of pretending that an untranslated page is Spanish.
Corrections
Report a problem through the contact form with the page URL, inputs used, expected result, and a primary source when relevant. Reproducible accuracy issues are prioritized over requests for additional content.
