Taking builds now
Tell me in one sentence what the app should do. I build it in Claude, ChatGPT and Google AI Studio, deploy it to a domain you own, and hand you the source. No builder platform in the middle. No forty-page proposal first.
Jean-Luc Benazet, Cambridge. Seasoned photographer, AI enthusiast, and the person who will actually write your app.
There is one question that decides everything: does anybody need to sign in? Answer that and the rest of the build follows. I will tell you which route you are on before you spend a penny.
Everything runs in the visitor's browser. One file, or a small set of them. Near-instant load, nothing to maintain, and it will still work in ten years on any host you like.
Live example: Poster Studio generates artwork in the browser before anything is paid for.
A proper server behind the app. Needed the moment you want members, saved work, money changing hands, or an AI model called without your API key sitting in public view.
Live example: Suno Hitmaker runs a members area across OpenAI, Claude and Gemini.
Every one of these is on its own domain, doing a real job, right now. Open them. That is the point of showing them rather than describing them.
visibilitypilot.co.uk · Node.js
Checks how visible a business is to AI search tools and language models, then says what to fix. Built for owners, not agencies. The kind of narrow, genuinely useful tool that is realistic to build and run yourself.
aiheadshotgenerator.co.uk · Node.js
Studio-quality headshots without the studio. Upload, process, download. The image pipeline, the upload handling and the quality judgement all come from thirty years behind a camera rather than a stock template.
sunohitmaker.co.uk · Node.js
Writes a full Suno brief in one pass: style, title and lyrics. Hard-locked BPM, structure templates, in-browser cover art at no API cost, and three AI providers with automatic fallback so a single outage does not take the app down.
posterstudio.biz · HTML + AI
Create, buy and print travel posters. Generation in the browser, a digital shop, and a route to physical prints. It feeds the Etsy shop directly, so the tool and the product are one business rather than a demo.
Open the app See what it sells
Whatever we are making, and whether you are watching or I am doing it for you.
Name the job it does and who it is for. "A UK lottery number checker" is enough to start. Clarity here saves hours later, and it saves you money.
HTML or Node, decided by whether anyone signs in. Then Claude and ChatGPT for building and reasoning, Google AI Studio for AI-powered features and quick prototypes. Three tools, no third-party app builder.
The description goes in, the first version comes out, and it runs. You will have something clickable far faster than you expect, which is the whole reason this works.
Read the error, give it back to the AI, change one thing, run again. This loop is the whole skill. Calm and incremental beats clever.
Deployed with SSL to a domain you own, source handed over, schema and llms.txt in place so AI tools can find it. A live link you can share is the goal. Polish after it exists, not before.
No retainer required, no platform to stay subscribed to, nothing held back to force a second invoice.
Three tools, used directly.
The app is written straight in these, so it is understood and it can be fixed.
The one-click app builders.
They look fast on day one. The output rarely lasts, and you are stuck the moment something goes wrong.
Visibility Pilot, AI Headshot Generator, Suno Hitmaker and Poster Studio can be rebranded and run on your own domain. The engineering is done, the bugs are already found, and you are live in a fraction of the time.
If people need to sign in, save their work, pay you, or use an AI model without your API key being visible, you need Node.js. Everything else should be static HTML: it is faster, cheaper to host and there is nothing to maintain.
A focused static HTML tool is usually days rather than weeks. A Node.js app with accounts and payments takes longer, because authentication, billing and hosting are their own jobs. Either way you get a clickable link early rather than a document.
It depends on the route and the scope, so it is quoted per job. Tell me in one sentence what the app should do and you will get a figure and a timescale back, along with an honest view on whether it is worth building at all.
Yes. The full source is handed over. There is no builder platform in the middle, no export fee and nothing you cannot take to another developer.
Yes. Visibility Pilot, AI Headshot Generator, Suno Hitmaker and Poster Studio can be licensed and rebranded under your own domain, which is usually far quicker than building from scratch.
Claude, ChatGPT and Google AI Studio, used directly. No one-click app builders. They look fast on day one, but the output rarely lasts and you cannot fix what you cannot see.
That is built in. Every app ships with the schema, llms.txt and page structure that language models need to describe and cite it. AI visibility is exactly what Visibility Pilot measures, so it is not an afterthought here.
Yes, and I would rather you did if the app is small. The walkthroughs are free on YouTube and the method above is the whole method. Nothing is held back.
Tell me what the app should do and who it is for. You will get back the route it needs, roughly how long it takes, and whether it is worth building at all.
