As answered by people managing ArakStudy and Cert Decoder.
ArakStudy's answer
The way we study hasn't changed in 100 years. Until now. While every other industry was getting faster, students were still studying the same way their grandparents did: reading static textbooks and highlighting paper notes. We saw a gap. Generative AI can do more than just write essays, it can be a personalized tutor.
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
ArakStudy's answer
Our primary audience is the STEM or Medical student who is overwhelmed by the volume of material and uses AI not to cheat on essays, but to automate the creation of study materials so they can prepare for exams 10x faster.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
ArakStudy's answer
Choosing an AI-powered tool like ArakStudy over traditional giants (Quizlet, Anki, Chegg) comes down to one fundamental shift: Efficiency through Automation.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
ArakStudy's answer
The "Unique Selling Proposition" (USP) of AI study tools is that they shift studying from passive consumption (reading notes) to active, personalized engagement.

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
