TOOLSBYJ / ABOUT
ToolsByJ is a growing platform by Janidu Sandaruwan, built around clear, practical browser tools for students, creators, small businesses, and everyday work.
THE IDEA
A useful tool should explain itself quickly, avoid unnecessary sign-up walls, and give a result without making people learn a new system first.
ToolsByJ starts with practical everyday work: planning study time, calculating GPA, working with text, preparing captions, and making simple invoices.
THE STANDARD
These are the rules used to decide what belongs on ToolsByJ and what needs more work before it is public.
Every public card should open something you can actually use today — not a feature that is only planned.
Current calculators and writing tools run in the browser unless a page clearly tells you something different.
Advanced file tools will be added only when privacy, limits, reliability, and testing are ready.

Notes, quizzes, mock exams, and reference sheets remain on the existing Study Hub while ToolsByJ grows around practical tools.
