Why GraphIt was made
As a third year engineering student in uni, and an IB alumni, I have had a lot of experience wasting precious time trying to make up graphs for IAs, reports, and engineering assignments. Particularly in economics, my choices were to sign up to some website where I needed to pay to access better quality downloads or basic features, or manually make mine in some application like Google Drawings. Of course, I could also personally code graphs in Python or MATLAB, but that is beyond the scope for a majority of high schoolers and university courses.
This is the main idea behind graphit.now, during my mid semester break in sem 1 2026, I made this site to help all students from different high school curriculums, and university courses, to make their graphing process much easier and more centralised. There are no accounts, you do not need to pay to get better quality images, and you do not need to bypass the system by screenshotting.
You can copy and paste, or download as PNG for all graphs at any time, absolutely free. There are ads on the site to cover hosting costs, but from my experiences before, ad revenue is very minute and well... Hopefully will be enough to cover the $50 I spent making the site haha.
