Find me on

Hi, I'm Terris. I'm a web designer in Singapore, and I design and code every web app myself.

Get an AI web app in Singapore built around one job it does well

I build web applications with AI where it actually saves time: drafting, sorting, summarising, answering, searching. Each app has logins, a database and the screens your users need, and starts with a focused first phase.

What an AI web app with me includes

An AI web app with me includes the product and the AI: scoping what it must do, screens designed for your users, logins and roles, a database, the AI features connected to a model with checks on what it outputs, payments if you charge for it, and hosting set up to run reliably.

  • Scoping: one job, done well, in a first phase
  • Screens designed for the people using it
  • Logins, roles and a database
  • AI features with checks on what the model returns
  • Payments and subscriptions through Stripe, if you charge
  • Hosting, monitoring and backups
  • Source code you own

How I build your AI web app

  1. Find the one job

    The task the app has to do well, who it's for and what success looks like. Everything else waits for a later phase.

  2. Design the screens

    The key screens designed and clickable, so you can try the flow before it's built.

  3. Build the app

    Logins, database and screens built, with the parts you can use shown to you along the way.

  4. Add the AI carefully

    The model connected with clear instructions, limits on cost, and checks on what it returns, so it fails safely when it's unsure.

  5. Launch and improve

    Deployed with monitoring, then improved from what real users do. The next phase is planned from that.

How much does an AI web app cost in Singapore?

Web applications with me start at SGD 12,140, scoped in hours and quoted as one fixed number. A smaller AI tool or feature starts at SGD 6,575. The AI model's running costs are yours and are quoted separately before you commit.

A web app with logins and a database

Custom web application

SGD 12,140From

Anything with a login, a dashboard, roles or a database behind it. No tier covers this honestly, so it is sized properly or not quoted.

  • Scoped in hours at SGD 110 to 150
  • One fixed number, extras priced separately
  • A smaller first phase offered where it splits cleanly

Dev shops quote SGD 20,000 to 50,000 for the same MVP because four people bill their part of it.

A smaller AI tool or feature

AI apps, chatbots and automation

SGD 6,575From

A chatbot on your own content, a workflow that runs itself, a model wired into the tools you already use.

  • Scoped against what your stack already does
  • Fixed price per phase
  • Running costs quoted separately and honestly

Model and hosting costs are yours and are quoted separately, usually SGD 30 to 200 a month.

Questions about AI web applications

How much does an AI web application cost?

With me, web applications start at SGD 12,140 and smaller AI builds at SGD 6,575, quoted as fixed numbers per phase. The AI model's usage costs are separate and depend on how much it's used.

Should I build an MVP first or the full product?

An MVP, almost always: the smallest version that does the main job for real users. It costs less, launches sooner, and shows you what to build next, instead of guessing.

Can you add AI to my existing web application?

Usually, yes. I look at how the app is built and where AI would save time, then add it as a feature connected to a model, with limits on cost and checks on the output.

Can the app take subscription payments in SGD?

Yes. Stripe handles subscriptions and one-off payments in SGD, with invoices and customer billing pages, and I build it into the app.

How do you handle logins and access?

With an established authentication service rather than a home-made one, roles for what each user may see and do, and every sensitive action checked on the server.

How do you keep the AI's answers reliable?

Clear instructions, the model given the right context, and checks on what it returns before a user sees it. Where a wrong answer would matter, a person approves it first.

How do you make an AI web app PDPA-compliant?

Collect only the personal data the app needs, say what it's used for, control who can see it, and be careful what's sent to the AI model. If personal data goes to a model provider overseas, the PDPA's transfer rules apply, so I keep it to what's necessary.

How long does it take to build an AI web app?

It depends on the scope, so the timeline is agreed with the scope before the work starts. A focused first phase is the fastest way to something your users can try.
