As answered by people managing PayFlowAI.dev and Cert Decoder.
PayFlowAI.dev's answer
PayFlow AI was built around a simple frustration: completing the work is often easier than getting paid for it. Freelancers and small agencies can lose valuable time repeatedly checking invoices, remembering when to follow up, and writing increasingly firm payment messages to clients. Instead of building another accounting platform, PayFlow AI was created to solve the specific problem of payment follow-up and revenue recovery—helping businesses spend less time chasing money and more time doing the work they are paid to do.
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.
PayFlowAI.dev's answer
PayFlow AI is built with a modern web SaaS stack including Next.js, TypeScript, React, Tailwind CSS, Supabase, and AI/LLM integrations. The platform uses Supabase for application data and authentication infrastructure, while AI services power personalized payment-message generation and revenue-recovery workflows. Supporting services are used for payments, email delivery, and production deployment.
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
PayFlowAI.dev's answer
The primary audience is freelancers, consultants, and small service-based agencies that invoice clients for completed work. This includes web developers, software consultants, marketing agencies, design studios, creative professionals, and other service businesses that regularly deal with pending or overdue client payments.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PayFlowAI.dev's answer
PayFlow AI is designed for businesses that don't need another complicated accounting platform—they need to stop spending time chasing overdue invoices. It provides a focused workflow for identifying outstanding payments, generating professional personalized reminders, and managing follow-ups while keeping the business owner in control. Its focus on freelancers, consultants, and small agencies makes it simpler and more targeted than broader accounting platforms.
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.
PayFlowAI.dev's answer
PayFlow AI is currently an early-stage product and is focused on onboarding its first group of freelancers, consultants, and small agencies. We are actively looking for early customers who regularly deal with overdue client invoices and want to test a dedicated revenue-recovery workflow.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
PayFlowAI.dev's answer
PayFlow AI focuses specifically on revenue recovery rather than trying to replace accounting or invoicing software. It helps freelancers, consultants, and small agencies turn overdue invoices into structured payment follow-ups using AI-generated, personalized messages that can become progressively firmer as payments remain outstanding. The product combines invoice tracking, AI payment reminders, follow-up workflows, and payment links around one specific problem: getting businesses paid for work they've already completed.

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
