Custom web application development for the use cases standard software does not cover

Evoya AI builds custom web applications for Swiss companies and public bodies – with artificial intelligence as an integral part and data that stays under your control.

What is a web application – and when is custom web application development worth it?

A web application is software that runs in the browser: you log in and start working, with no installation, whether at the office, at home or on a tablet. Custom web application development pays off where standard software only covers your process through workarounds, spreadsheets or duplicate data entry.

Unlike a website, which informs, a web application does work: it captures data, checks it, controls workflows and exchanges information with ERP, CRM or Microsoft 365. Typical examples are customer portals, internal tools, dashboards and SaaS-like business applications.

Evoya AI, based in Uster in the Canton of Zurich, builds these applications with AI as an integral part – for example to extract data from documents automatically or as an assistant inside the application. AI-assisted development makes our projects noticeably faster than classic software projects.

Your benefits

Custom software that fits the way you work

Instead of bending your processes to fit a standard product, we build the application around how you work.

Exactly your process

The application reflects your workflows, roles and rules. No licences for features you do not need.

AI built in, not bolted on

Reading documents, checking data, drafting text or answering questions: AI features are part of the application, not a separate tool.

Data under control

Hosting in Swiss data centres by default, processing location selectable (Switzerland, EU, USA, on-premise). FADP and GDPR compliant, and your data is never used to train models.

Connected to your systems

Interfaces to ERP, CRM, Microsoft 365 and specialist software mean data is entered only once.

Faster delivery

AI-assisted development noticeably shortens projects compared with classic software projects. You see working versions early.

Grows with you

New modules, user groups or AI features can be added step by step without rebuilding the application.

Use cases

Web applications we build

From lean specialist tools to portals with many users – always focused on where AI takes real work off your hands.

Document processing and order capture

The application reads orders, invoices or forms from e-mails and PDFs, validates them and passes them to your ERP. A control interface shows what needs approval.

Customer and partner portals

Customers, partners or citizens submit requests, track their status and upload documents. An AI assistant answers questions around the clock.

Internal tools and business applications

Replace spreadsheets and isolated solutions with one central application with roles, workflows and audit logs.

Dashboards and reporting

Key figures from several systems in one place, complemented by AI summaries and analysis in plain language.

Data capture and analysis in education and healthcare

Evaluate handwritten tests, transcribe conversations or prepare reports – with data processed in Switzerland.

SaaS-like business applications

Multi-tenant applications you use yourself or offer to your own customers as a service.

Approach

How we develop your web application

Clear steps, early results and ongoing alignment with your team.

  1. 1

    Analysis and target picture

    We clarify the process, users, interfaces and data protection requirements, and identify where AI measurably saves effort.

  2. 2

    Concept and prototype

    A clickable prototype shows early on how the application will work, so you decide on the basis of something tangible.

  3. 3

    Iterative development

    We develop in short cycles and regularly deliver working versions that you test with real data.

  4. 4

    Testing, security and rollout

    Functional and security testing, data migration and staff training prepare the production launch.

  5. 5

    Operation and further development

    After go-live we operate, monitor and extend the application – in Swiss data centres if you wish.

Why Evoya AI

Why choose Evoya AI for your web application

25+ years of experience

Our team brings more than 25 years of experience in software projects for Swiss companies.

Our own AI platform

We run our own AI platform with more than 30 language models. Your application uses the right model for each task without being tied to a single vendor.

Swiss data protection

Hosting in ISO 27001-certified Swiss data centres by default, FADP and GDPR compliant. Inputs are never used for model training.

Proven results

At ASTORtec, manual entry per order fell from around 10 minutes to 1–2 minutes. At BWS Uster, the AI profile analysis saves 30–60 minutes per test.

Frequently asked questions

The cost depends on scope: the number of features and user roles, interfaces to third-party systems, AI features and requirements for security and operation. After a short analysis, Evoya AI provides a transparent quote. Thanks to AI-assisted development, our projects are noticeably faster than classic software projects.

A website informs visitors. A web application is software in the browser that users work with: capturing data, controlling workflows, processing documents. It therefore needs user management, permissions, a database and often interfaces to other systems.

Off-the-shelf software is usually the better choice for general tasks such as accounting or e-mail. Custom software pays off when your process differs, several systems have to be connected or manual work such as retyping documents takes a lot of time. Often a web application complements existing standard software rather than replacing it.

It depends on scope, interfaces and the amount of coordination required. Evoya AI works iteratively, so you see a working prototype early. AI-assisted development makes our projects noticeably faster than classic software projects.

AI takes on specific tasks inside the application: it extracts data from PDFs and e-mails, recognises handwriting, summarises content or answers questions as an assistant. Evoya AI uses its own platform with more than 30 language models and picks the right model for each task.

By default in ISO 27001-certified data centres in Switzerland. The processing location is selectable: Switzerland, EU, USA or on-premise. Solutions comply with the Swiss FADP and the GDPR, with zero data retention, and your inputs are never used to train models.

Yes. Evoya AI web applications connect via APIs to ERP, CRM, Microsoft 365 or Active Directory. At ASTORtec, the application transfers validated orders directly to the Europa3000 ERP.

A Swiss partner knows the Swiss Federal Act on Data Protection (FADP), understands the needs of SMEs and public bodies and is available for on-site workshops. Evoya AI is based in Uster in the Canton of Zurich and hosts in Swiss data centres by default.
