As answered by people managing TextBoi and Cert Decoder.
TextBoi's answer
TextBoi was created to solve a simple but frustrating problem: constantly switching between apps just to fix or translate text. The goal was to build a tool that works instantly, anywhere on your desktop, without interrupting your workflow. By combining AI writing assistance with a shortcut-based interface and OCR capabilities, TextBoi was designed to make writing support as fast and seamless as possible.
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.
TextBoi's answer
TextBoi is built using modern desktop and cloud technologies, combining AI language models for grammar correction, rewriting, and translation with a lightweight desktop application for real-time interaction. It also integrates OCR technology to capture and process text from the screen, enabling a seamless “write anywhere” experience across different applications.
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
TextBoi's answer
TextBoi is designed for professionals, students, and anyone who writes frequently across different applications. This includes remote workers, developers, marketers, content creators, and non-native English speakers who need fast, reliable writing assistance without breaking their workflow.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
TextBoi's answer
Most writing tools require users to copy and paste text into a separate interface. TextBoi removes that friction completely. With a single shortcut, users can fix grammar, rewrite sentences, or translate text directly in their current workflow without interruption. This makes TextBoi significantly faster and more convenient than tools like Grammarly or DeepL, especially for people who work across multiple apps throughout the day.
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.
TextBoi's answer
TextBoi stands out by eliminating the traditional copy-paste workflow. Instead of switching between apps, users can instantly fix grammar, rewrite, or translate text anywhere using a simple shortcut (Cmd+C+C on Mac, Ctrl+C+C on Windows). It works across all applications — browsers, documents, messengers, and more — and even supports OCR, allowing users to process text directly from images or any part of the screen. This “anywhere, instant” experience is what makes TextBoi fundamentally different from traditional writing tools.

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
