Simple tools. Straight answers.
StraightTools is a collection of free, no-signup calculators and everyday utilities. The site is designed around fast answers, readable explanations, and tools that work directly in a modern browser.
How the site is funded
StraightTools may display advertising. Ads help keep the tools free to use.
Accuracy
We test calculations and provide formulas where useful, but results can still be approximate. Important financial, legal, tax, health, or other professional decisions should be verified with an appropriate professional or authoritative source.
What we publish
StraightTools focuses on small, practical utilities: calculators, converters, date and time tools, and text helpers. We do not require an account to use the core tools.
How pages are selected for search
Not every generated variation is intended to appear in search engines. Repetitive pages can remain available for users while being marked noindex. We keep a smaller search-facing set that has a distinct purpose, explanatory context, and internal links to the main interactive tool.
Corrections
If a formula, explanation, or result appears incorrect, send the page URL and a reproducible example to contact@straighttools.com. Corrections can be incorporated into the shared generator so the fix applies consistently.
