About us

Software engineering and AI — for companies that need systems, not chaos

AI centar is your partner for business application development and practical AI in real workflows.

Software development

We build real business systems that get the job done — not just brochure websites.

Process understanding

We start with how your team actually works, and only then choose the technology.

AI implementation

We embed AI where it delivers measurable time savings and better decisions — not as decoration.

Long-term support

From idea to application, training, and maintenance — we stay your technical partner.

Our mission

We build tailored business applications and enhance them with AI that saves time, cuts manual work, and improves business decisions.

Services

From app development to AI training and support

Full range of services from a serious software company — focused on business value.

Custom applications

We build software around your business process, not the other way around — no generic templates. Web apps, internal systems, admin panels, CRM, ERP, workflows, and reports, connected to the tools you already use, so data never has to be retyped.

AI integration into applications

Our key strength: we embed AI directly into your applications and data, not as a separate external chat. Assistants, document analysis, smart search, and task automation run inside your system, with connections to OpenAI or other providers of your choice.

Business process automation

We eliminate the repetitive manual work that eats up hours and creates errors. We automate document processing, notifications, data synchronization, and workflows, so routine tasks run on their own — accurately and on time.

Training on working with AI tools

Hands-on training tied to your team's real work, not generic presentations. We show how ChatGPT and related tools can speed up sales, marketing, administration, support, and management, with safe and responsible use.

Consulting & digital transformation

We help you clearly see what is worth digitizing, automating, or improving with software and AI — and what isn't. You get a concrete, prioritized plan with an impact estimate and realistic steps, instead of expensive experiments.

Maintenance & support

After delivery we remain your technical partner — we don't disappear. We handle hosting, monitoring, fixes, and upgrades, and keep developing the application as your business grows and changes.

Applications & products

Ready solutions we already use in production

Besides custom development, we offer products for education, sales, and operations.

Automatic document reading

Contracts, quotes, and orders are read and processed in seconds, with controlled, role-based access.

Summaries and reports in one click

The system generates summaries and reports from your business data, not from empty prompts.

Smart search across company data

A single natural-language query finds information in your catalog, clients, orders, or projects.

AI support for employees and customers

Chatbots and assistants respond in the context of your business, with clearly defined boundaries.

Recommendations and process optimization

From first call to long-term support

Clear, predictable process — no surprises in scope or delivery.

Solution proposal

We define the scope, modules, and integrations, and pinpoint exactly where AI delivers the most value — with a clear timeline and budget.

Application design & development

We build the system iteratively, in clear phases with regular progress reviews, so you can always see what's done.

AI integration & automation

We embed AI features and automation into your real workflows, so they work on your data from day one.

Testing & user training

We thoroughly verify quality and train your team to use the system safely and independently from day one.

Maintenance & ongoing development

We remain your technical partner for support, upgrades, and new features, as the application grows alongside your business.

Sales teams

Leads, quotes and follow-ups in one flow — no contact slips through.

Support teams

Tickets, knowledge base and AI replies — faster answers with less repetition.

Technologies

Tools and platforms we build with

We use proven, modern technologies — from frontend and backend to AI and cloud infrastructure.

Frontend

Fast, modern interfaces with React and Next.js, type-safe code in TypeScript and a consistent design system via Tailwind — apps that load fast, look sharp and stay easy to maintain.

Backend

Reliable logic and data: services in Node.js and Python, a PostgreSQL database and Redis caching — stable, secure and ready to scale without downtime.

AI / ML

The heart of our edge. We build AI directly on your data: RAG search and chat over documents, embeddings and vector search, AI agents and task automation. We connect OpenAI and other models — including local/on-prem options — with cost and role controls and a full audit trail, no black box.

Cloud & DevOps

Secure hosting and delivery: Azure and AWS, containerization with Docker and fast deploys — with monitoring, autoscaling and high availability.

AI training

Practical team training — no academic jargon

We help employees use AI tools in daily work — clearly and practically.

Training tailored to your real work

We build the program around your team's real tasks — examples from your processes, documents and everyday situations, not generic slides.

Prompt writing and efficient AI workflows

How to write clear prompts and get accurate, usable results from ChatGPT and similar tools — with verification and fewer mistakes.

Productivity for daily tasks

Practical workflows that speed up daily work: writing, summarizing, analysis, and preparing documents and reports.

AI in sales, marketing, admin, and support

AI by role — concrete use in sales, marketing, administration and support, with examples for each team.

Safe and responsible AI in the company

What's safe and what isn't: data protection, confidentiality, clear boundaries and responsible AI use across the company.

Examples from your processes and documents

We work on your real examples — documents and processes — so the team can apply what they learn right away.
