As answered by people managing Cert Decoder and TuckHQ.
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.
TuckHQ's answer:
Built by Nishant, a solo developer from India. After 6 years of Google Drive chaos - receipts, contracts, client files, photos all unsorted, he built Tuck to solve his own problem. Launched April
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
TuckHQ's answer:
Next.js, Google Drive API, Groq AI, Drizzle ORM, Neon (PostgreSQL), Stripe, Tailwind CSS
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
TuckHQ's answer:
Working professionals aged 22-35 who have accumulated years of random files in Google Drive and want them cleaned up without building a system. Freelancers, remote workers, and anyone with ADHD who finds manual organization impossible to maintain.
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.
TuckHQ's answer:
TuckHQ is the only organizer that handles any file type (including photos and scans) with zero configuration. Competitors like Filently focus on documents only. Google's Gemini moves 5 files at a time and requires manual prompting. TuckHQ is fully automatic, works in seconds, and costs $7/month, half the price of comparable tools.
Cert Decoder's answer
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
TuckHQ's answer:
Most file organizers require you to define rules for every document type. Tuck uses AI to read the actual content of each file and decide where it belongs, no rules, no setup, no maintenance. It works on any file type: PDFs, Word docs, Excel sheets, photos, and scans.

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
