Tools Methodology

Most tools run entirely in the browser. Text transformations, developer utilities, image processing, unit conversion, finance calculators, health calculators, and date utilities generally use client-side JavaScript and browser APIs. This improves speed and keeps private input on the visitor's device.

• Finance tools use standard formulas such as EMI amortization, compound interest, GST percentage math, discounts, and SIP projections.
• Health tools use common published formulas such as BMI categories, BMR estimates, TDEE estimates, hydration rules of thumb, due-date estimates, and cycle projections.
• Unit converters use fixed conversion factors and expose precision controls where rounding matters.
• Developer tools use native parsers or established libraries where practical instead of hand-rolled parsing.
• Image tools use browser image, canvas, compression, and file APIs where possible.

Career tools that analyze resumes, compare job descriptions, or draft letters may send the text you provide to a server-side AI endpoint only after you trigger the action. These tools are intended for drafting and review support. They do not replace professional career, legal, immigration, or employment advice.

Tools are checked against representative examples, edge cases, and browser behavior. Content pages include usage notes, common mistakes, and FAQs to document assumptions. If a result matters for a medical, legal, tax, investment, or financial decision, verify it with a qualified professional before relying on it.
