Hey Product Hunt 👋 I run a small studio in Delhi NCR building websites, apps and AI workflows. Most of our clients are startups and local businesses — the kind that don't have a tools budget. Last year I kept watching the same thing happen. Someone needs to generate schema markup, or send one invoice, or make a QR code for a shop counter. They Google it, land on a "free" tool, fill in everything, hit generate — and get a watermark, a signup wall, or a "3 free credits remaining" popup. My own team was doing this several times a week. So we started building our own. It got out of hand. There are now 15 of them: → Schema Markup + FAQ Schema generators (valid JSON-LD, no hand-writing) → Invoice Generator with GST for India → QR Code Generator, including UPI QRs → JSON Formatter, Word Counter, Favicon Generator → Website Speed Test → ROI Calculator, UTM Builder → Colour Palette Generator with WCAG contrast checking → Business Name, Slogan and Email Signature generators Plus 1000_ AI prompts & Skills organised by role, and the one I'm most curious to hear your thoughts on: an AI Visibility Checker that tells you whether ChatGPT actually knows your brand exists. Search is shifting from ten blue links to one answer, and most businesses have no idea whether they're in it. This is our first attempt at measuring that. The rules we set ourselves: • No account. Ever. • No watermark, no credit limits. • Everything runs in your browser — we don't store your invoice, your JSON, or your brand name. • Free because they feed our actual business (we're an agency), not because there's a paid tier waiting behind them. What I'd genuinely like from you: 1. Which tool is missing? I'll build it. 2. Is the AI Visibility Checker useful or a gimmick? Be blunt. 3. Anything broken — tell me and I'll fix it today. I'll be here all day. Thanks for having us 🙏
