As answered by people managing GradeAI and Cert Decoder.
GradeAI's answer
GradeAI was born from seeing firsthand the time teachers spend on creating and grading exams—time that could be used for teaching and inspiring students. And online learning platforms where classes have no limits they spent $1000 in hiring TA specially during exam time. I noticed that educators were overwhelmed by manual processes, so I decided to create a tool that leverages AI to handle these repetitive tasks, freeing teachers to focus on what they do best. With a mix of passion for education and expertise in technology, I set out on a journey to build a platform that makes life simpler for educators while providing deep insights into student performance.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
