Online Student Tools - Free online tools for students, from GPA to citations

Hi Product Hunt! 👋 I built Online Student Tools because students often have to jump between different websites just to handle simple academic tasks. I wanted to put those everyday tools in one place — GPA and grade calculators, word and page calculators, citation tools, GPA/ECTS converters, thesis formatting, and even simple geometry tools. Everything is free to use and works directly in the browser without requiring an account. I'd love to hear from students, teachers, and anyone who works with academic tools: what tool would you want me to add next?
