Directory FAQ
Answers for search, filters, and tool discovery
How do category filters work in the tools directory?
Category filters narrow the directory to a specific financial workflow such as Loans, Taxes, Planning, or Debt. The filter state is preserved in the URL so shared links open with the same view.
Can I search for tools with partial terms or typos?
Yes. The directory supports real-time search, autocomplete suggestions, and typo tolerance so users can find calculators even when the exact tool name is not entered.
Which tools are surfaced first?
Popular, featured, and newly added tools are prioritized through quick filters and spotlight sections so the highest-intent calculators remain easy to reach.
