Who it is for
A company with a working site or app that wants one useful AI feature, such as search that understands questions, a smart form or a recommendation, without replacing what already sells.
What is included
- 1 AI feature wired into your existing site or app, with every model call made on the server
- 1 data source the feature may read, such as your catalogue, help pages or bookings
- 30 real cases, including failure states, frozen and run before acceptance
- Up to 3 kinds of case the feature hands to a person or declines, instead of guessing
- 1 monitoring view showing usage, cost and failed answers after launch
Not included
- Model, vector database and hosting fees (paid by you to each provider)
- Rebuilding or redesigning the existing site or app
- Writing, cleaning or migrating the content the AI reads
- Legal review of disclosures, privacy notices and data-processing terms
- Tuning and support after handoff
How the work runs
- 01
We pick the one feature worth building first, the data it may read and the cases where a person must decide.
- 02
We collect 30 real cases with the answers you expect, so success is agreed before any code.
- 03
We build the feature into your product, run the cases and fix what fails.
- 04
We launch on your hosting with the monitoring view on, then hand over the note and the test set.
Example
CLIENT Client project
SB Excursions, a tour company in Bali: a five-language site where an AI planner lays out a week on the island next to the ordinary tour categories, and tour pages hand the conversation to WhatsApp with the tour named, so booking stays with the company's team. Labelled CLIENT.
What this does not prove: The planner was built together with the site, not added to existing code, and the case publishes no usage, accuracy or cost figures for it.

In the signed-in VITON ID cabinet, the assistant answers questions about products and studio packages from its own catalogue, replying in the member’s language with cards and prices. Only when neither the catalogue nor its fixed replies fit does the question go to a self-hosted language model.

Our private assistant with a 3D memory planet: it wakes to an open palm, answers aloud, searches its memory graph and shares a workbench for assembling parts by hand. We show it in a one-minute trailer filmed from the real interface.

CONCEPTConcept — not a commissioned project
VOXA — Bank of the Future
Concept site · three.js · voice · English, Russian · 2026
VOXA is a fictional bank of the future, and this is the site VITON13 built for it as a concept for banks and fintech products. A camera flies through one three.js world with ten features; each opens a working phone app where a visitor pays a friend by voice, saves for a shared dream, buys a flight that turns into a boarding pass or designs a card, and a closing scene with two Veo 3.1 films hands the microphone to the visitor.

AI web application development — scope and cost
The price of AI web application development changes with inputs, dependencies and recovery work. This guide uses AI product architecture and Human review workflow to separate a quotable core from optional scope.
Open the article↗Questions people ask before buying
01Do we need to rebuild the site first?+
No. The feature is added to the product you run today, through its code or its API. If the current code cannot take it safely, we say so before any work is paid.
02Will our data train someone else's model?+
Model calls go through your own provider account with training on customer data switched off where the provider allows it, and the feature reads only the source agreed in writing.
03What happens when the AI gets it wrong?+
The 30 test cases show where it fails before launch. Cases it should not decide go to a person or get a clear refusal, and the monitoring view shows failures after launch.
04How much will it cost to run each month?+
That depends on the model and the traffic. The monitoring view shows the real cost per request from day one, and we estimate it before building from your expected volume.
05Which model do you use?+
The one agreed in the written scope, chosen for your language, your data rules and your budget. Switching providers later is a change of settings, not a rebuild.
06Can we add more features later?+
Yes. The first feature sets up the server calls, the test set and the monitoring, so each next one is a smaller, separately quoted step.
