Three business tools live and running
Three tools that answer the questions a business owner cannot answer by looking at their own website: can search engines and AI assistants find you, what is missing, and which businesses near you have the same problem. Built, hosted and run by one person in Cambridge.
Cambridge, UK. Founded and run by Jean-Luc Benazet.
Each one is live on its own domain, built and hosted here, and answers a different part of the same problem. Audit your own site, watch how it changes, or find the businesses near you with the same gaps. Click any of them and use it now.
Node.js
Audits one website end to end: classic SEO, how it reads to AI assistants, and the Google Business Profile. Then keyword research, rank tracking, competitors and backlinks on top, so what comes back is a marketing plan rather than a list of errors.
Made for the owner who wants the whole picture in one place: what is wrong with the SEO, how AI assistants actually read them, and what to do about the marketing next.
Node.js
Scores businesses against ten observed gaps, from thin content and missing structured data to being invisible in AI answers, and weights each one. Then tracks what happens next, from found to client, so the pipeline is a fact rather than a feeling.
Made for anyone running outreach who wants the pipeline to be a fact rather than a feeling.
Node.js
Sweeps 74 trades across Google Maps, Yell, Yelp, Thomson Local and FreeIndex, merges the duplicates, checks who has no website and who has a weak Google Business Profile, and drafts the outreach. Behind a passcode, so the numbers stay yours.
Made for the web designer or marketer who would rather spend the morning talking to prospects than building the list.
Two routes, and the honest answer is that most businesses need the first one. I tell you which before you spend anything.
Everything runs in the visitor's browser. Nothing to maintain, almost nothing to host, and it loads instantly. Right for a single-purpose tool that does one job well.
A real server behind it. Needed the moment you want people to sign in, save their work, pay you, or use an AI model without your API key sitting in public.
Four steps. No discovery phase, no forty-page proposal, no third-party app builder in the middle that you cannot debug when it breaks.
One sentence naming what the app does and who it is for. If we cannot write that sentence, the app is not ready to build.
Logins, payments or saved data mean Node. Everything else stays static, which is faster and cheaper for you.
Built straight in Claude, ChatGPT and AI Studio, then deployed. You click it and tell me what is wrong.
One change at a time until it does the job. Then it goes to your domain and you own the lot.
Built the same way, on their own domains, and still live. A food label scanner, a poster shop that sells what it generates, a Suno brief writer, and a headshot generator.
health-scan.co.uk
Scan a barcode or photograph the label, and get an evidence-aware read on nutrition, allergens, additives and processing. Built against UK front-of-pack thresholds, and deliberately not a fear machine: an additive is not automatically harmful, and missing data lowers confidence rather than inventing precision.
Free to use, no account, no key. For anyone who wants to know what is in the trolley before it reaches the till.
posterstudio.biz
Generates vintage-style travel posters and sells them as digital downloads. The app that sells its own output.
Open to everyone, and the clearest example of what I mean by an app that pays for itself.
Node.js
Builds a complete Suno brief in four steps: genre fusion, artist blend, reference vibe and structure. Everything it writes is original, and the tracks come out as Bass Mansion.
Made for anyone writing in Suno who is tired of guessing at what to put in the style box.
Node.js
Give it three to five reference photos and it holds your face steady across the whole set. One image, or four coordinated shots that look like they came from the same sitting. An identity lock decides how far it is allowed to stray.
Great for professional photographers who want to reach clients anywhere in the world, without either of them leaving the house.
The walkthroughs are free and they show the real thing, on screen, start to finish. If a tool is not good enough, I say so. The prompt packs are there for when you would rather not start from a blank page. No upsell ladder, no 97-module course.
The five-step loop I use on every build, the three tools I actually use, and the one-click builders worth avoiding.

Browse on GumroadVisual Network builds and runs three business visibility tools: Visibility Pilot audits a single website, Beacon scores and tracks businesses against ten observed gaps, and Lead Finder sweeps 74 trades across five directories. HealthScan UK, Poster Studio, Banger Forge and the AI Headshot Generator are also live. The same builds are available to order, as a static HTML tool or a full Node.js app.
A static HTML app runs entirely in the browser. It is fast, cheap to host and ideal for a single-purpose tool such as a calculator, checker or generator. A Node.js app runs on a server, so it can hold user accounts, save data, take payments and keep AI API keys hidden. If the app needs logins or billing, it needs Node.
A focused static HTML tool is usually days rather than weeks. A Node.js app with accounts and payments takes longer, because of the parts that are not the app itself: authentication, billing and hosting. You get a working link early and we improve it from there.
Yes. Some are sold direct as subscriptions or one-off purchases, some are licensed, and some are built to order for a business that wants its own. Poster Studio also sells the artwork it produces, and the Etsy shop sells the poster downloads.
Yes. The walkthroughs on YouTube and the guides on this site are free, and the prompt packs are there for anyone who would rather not start from a blank page. Building for clients and teaching sit side by side.
One sentence is enough to start. I will tell you whether it wants HTML or Node, roughly how long it takes, and whether it is worth building at all.
Interface only. This one runs on my own keys, or a client's.
