About Tools Hab

A focused library of useful online tools designed to answer common questions quickly and clearly.

What we build

Tools Hab brings together finance calculators, health references, date and math helpers, student tools, PDF utilities, image tools and developer helpers. Each tool has its own page so users can land directly on the exact task they need.

Our design principles

• Useful first: results should be understandable, not just technically correct.
• Privacy-first: many tools run entirely in the browser.
• Fast: the site uses a lightweight static architecture.
• Transparent: finance and health tools show important limitations.

Accuracy

We aim to use standard formulas and clearly stated assumptions. However, laws, tax rules, lending offers and health guidance change over time. High-stakes decisions should always be verified with current official or professional sources.
