As answered by people managing CaptainShot and Cert Decoder.
CaptainShot's answer
CaptainShot began with a personal frustration. I was taking screenshots to remember useful things such as travel details, purchases, documents, technology research, ideas, and conversations, but they quickly became buried among thousands of images in Photos.
I wanted a way to turn that growing archive into something private, searchable, organized, and genuinely useful.
The first version launched a little over a year ago. Since then, CaptainShot has evolved substantially through user feedback, with continuous analysis, visual and OCR search, SmartData extraction, dynamic selections, reminders, image editing, and native apps across the Apple ecosystem.
The original goal remains the same: make everything people capture useful again without compromising their privacy.
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.
CaptainShot's answer
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
CaptainShot's answer
CaptainShot is designed for iPhone, iPad, and Mac users who save large numbers of screenshots and want an easier way to organize, search, and reuse them.
Its audience includes students, researchers, developers, designers, journalists, travelers, shoppers, content creators, knowledge workers, and anyone who uses screenshots to remember useful information.
It is particularly relevant to privacy-conscious users who prefer local processing rather than cloud-based image analysis.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
CaptainShot's answer
CaptainShot offers a broader workflow than a traditional screenshot manager. It can automatically analyze and organize images, search both text and visual content, extract useful SmartData, suggest reminders, create dynamic selections, annotate images, and help users review or act on what they saved.
It is also built specifically for the Apple ecosystem, with native apps for iPhone, iPad, and Mac.
Its privacy-first architecture is a major differentiator: core OCR, visual analysis, organization, and search are performed on device, without uploading screenshots to CaptainShot’s servers or requiring an account.
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.
CaptainShot's answer
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
CaptainShot's answer
CaptainShot combines screenshot organization, OCR, visual search, structured data extraction, reminders, image editing, and knowledge management in one native Apple app.
Its core analysis runs directly on the device. Screenshots are not uploaded to CaptainShot’s servers, no account is required, and the app includes no advertising, tracking, or user profiling.
Unlike tools focused mainly on capturing screenshots, CaptainShot is designed to make existing screenshots and imported images searchable, organized, and actionable across iPhone, iPad, and Mac.

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
