Questions & Answers

As answered by people managing Cert Decoder and Notes2Pic.

What's the story behind your product?

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.

Notes2Pic's answer:

I, Jeruel Richard — founder and CEO, was looking for a cheaper alternative to Pika whilst repurposing my Substack Notes to Instagram. Using Gemini to create the images got exhausting and painfully slow really quick, so i decided to build a tool that creates me the images with pasted content, in seconds.

Which are the primary technologies used for building your product?

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

Notes2Pic's answer:

  • React+JSX
  • Vite
  • Javascript
  • Supabse for Auth and profile storage
  • Freemius for pricing.

How would you describe the primary audience of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Notes2Pic's answer:

Notes2Pic is built mainly for writers, creators and solopreneurs.

Why should a person choose your product over its competitors?

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.

Notes2Pic's answer:

Notes2Pic offers the ability to paste the content directly inot a textarea in-studio rather than waiting to make a tweet first and pasting the link afterwards. This allows users to create tweets/Substack Notes and Instgram content at the same time without waiting for the short-form content to drop first.

Who are some of the biggest customers of your product?

Cert Decoder's answer

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

Notes2Pic's answer:

    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
