Study Buddy Tools is a free collection of online tools for high school, college and university students around the world. Whether you are checking your GPA, working out what you need on a final exam, hitting an essay word limit or formatting a reference list, our goal is simple: give you a clear, accurate answer in seconds.

What we believe

• Free for everyone. Every tool is free to use, with no account, no paywall and no email required.
• Private by design. Our tools run in your browser. What you type into a calculator, word counter or citation generator is not uploaded or stored.
• Show the working. Each tool page explains the formula or rules behind the result, with a worked example, so you understand your answer instead of just copying it.
• Simple and fast. No clutter, no pop-up sign-ups. Open a tool, get your answer, get back to studying.

Our tools

How we check accuracy

Our calculators use standard, widely published methods, such as the US 4.0 GPA scale, weighted averages, and the WHO adult BMI categories. Our citation generator follows the published rules of APA 7th edition, MLA 9th edition and the common Harvard style. Grading scales and referencing rules can differ between schools, so we always recommend checking your own school’s guidelines for anything important.

How the site is funded
