AI systems that do real work in your business

We design, build and run AI agents, document intelligence and custom LLM applications for companies that want measurable results, not demos.

Services

What we build

Four service lines, one principle: every system ships with monitoring, documentation and a handover you can maintain.

AI agents & automation

Autonomous agents that handle email, scheduling, data entry, lead collection and multi-step back-office workflows.

  • Multi-agent pipelines with human checkpoints
  • Integration with Gmail, CRM, ERP, Slack
  • Voice and chat agents for customer calls

RAG & LLM integrations

Chatbots and assistants that answer from your own documents, contracts and knowledge bases, with sources cited.

  • Retrieval pipelines over PDF, Word, email, databases
  • Multi-provider setups (Claude, OpenAI, local models)
  • Evaluation sets and hallucination control

Custom AI web applications

End-to-end products: document generators, OCR converters, internal tools and SaaS with AI at the core.

  • Python / FastAPI / Node backends
  • Modern frontends, PDF and Word export
  • Cloud deployment, auth, billing

AI consulting & audit

Where AI pays off in your operations, what it costs, and what to build first. Review of existing AI systems and prompts.

  • Use-case discovery workshop
  • Architecture and cost estimate
  • Security, data and compliance review
How we work

From first call to a running system in four steps

01

Analysis

We map your process, data sources and constraints. You get a written scope with a fixed price or a clear hourly estimate.

02

Prototype

A working prototype on your real data within days, not months. We test accuracy and cost before committing to the full build.

03

Implementation

Production build with integrations, logging, evaluation and documentation. Code is delivered to your repository.

04

Maintenance

Monitoring, model updates and improvements under a monthly agreement, or a full handover to your team.

The company

ArhistrategStudio

An AI engineering studio based in Belgrade, Serbia, working with clients across Europe and the region. We build with the same tools we sell: our own retrieval engine, agent frameworks and document pipelines run in production every day.

Engineering first. Every deliverable is code in your repository, with tests and documentation.

Honest scoping. If AI is not the right tool for the job, we say so before you pay for it.

Data stays yours. On-premise or EU-hosted options, no training on client data.
