I run a small studio in Delhi NCR building websites, apps and AI workflows. Most of our clients are startups and local businesses โ 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 โ 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:
โ Schema Markup + FAQ Schema generators (valid JSON-LD, no hand-writing) โ Invoice Generator with GST for India โ QR Code Generator, including UPI QRs โ JSON Formatter, Word Counter, Favicon Generator โ Website Speed Test โ ROI Calculator, UTM Builder โ Colour Palette Generator with WCAG contrast checking โ Business Name, Slogan and Email Signature generators
Plus 254 AI prompts 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: โข No account. Ever. โข No watermark, no credit limits. โข Everything runs in your browser โ we don't store your invoice, your JSON, or your brand name. โข 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 โ tell me and I'll fix it today.
I'll be here all day. Thanks for having us ๐

Scult Tools's answer
We run Scult, a web, app and AI development studio in Delhi NCR. Most of our clients are startups and local businesses without a software budget.
The same thing kept happening internally. Someone needed schema markup for a client page, or a QR code for a shop counter, or a quick invoice. They'd Google it, land on a free tool, fill in every field โ and then get a watermark stamped across the output or a signup wall. Our team was losing time to this several times a week.
So we built our own version of the one we needed most. Then another. It got out of hand, and at fifteen we stopped and put them on one site.
The AI Visibility Checker came from a different frustration. Our clients kept asking where they showed up in Google, but more of their customers were asking ChatGPT for recommendations instead of searching. Nobody could tell them whether they appeared in those answers, so we built something that tries to.
Scult Tools's answer
Most "free" online tools aren't. You fill in the form, hit generate, and then hit a signup wall, a watermark, or a "2 of 3 free credits used" popup. Scult Tools has none of that โ 15 tools, no account, no watermark, no usage cap, nothing to upgrade to.
Two things you won't find bundled elsewhere. First, it's built with India in mind: GST-ready invoicing and UPI payment QR codes are first-class features, not afterthoughts. Second, the AI Visibility Checker โ instead of only optimising for Google, it tells you whether ChatGPT and other AI assistants actually mention your brand when someone asks for a recommendation.
The tools also run in your browser rather than on our servers, so what you type stays with you. And there's a library of 254 AI prompts organised by role alongside them.
Scult Tools's answer
Because you'll finish the task instead of hitting a wall halfway through it.
No signup, no watermark on the output, no daily limits, no credit system, and no paid tier the free version is quietly crippled to sell. If you need one invoice, one QR code, or one block of schema markup, you get it in under a minute and leave.
It's also one site instead of fifteen. Most people bounce between a different sketchy tool site for every small job, each with its own popups. This is one bookmark covering SEO, invoicing, development, design and productivity.
The honest version of why it's free: we're a web and AI development studio. These tools started as internal utilities for our own team, and making them public is how people discover what we do. That's the entire business model โ there's no bait and switch coming later.
Scult Tools's answer
Marketers, SEO specialists, freelancers, agency teams, small business owners and developers โ people who need a specific small job done and don't want to sign up for a platform to do it.
Concretely: an SEO adding schema markup to a client page, a freelancer sending an invoice with GST, a shop owner printing a UPI QR for the counter, a developer pasting in messy JSON at 1am, a founder trying out business names, a designer checking whether their colour palette passes WCAG contrast.
The core is India โ GST invoicing and UPI QRs reflect that โ but nothing is region-locked, and tools like the JSON formatter, schema generator and word counter get used worldwide.
