What we do

Websites, apps and systems —
with AI inside

We build websites, web and mobile apps and AI automation systems. Every project with built-in intelligence — own infrastructure, full code ownership, no SaaS subscriptions.

Our principle: we design, write code, and set up the infrastructure
Instead of reselling SaaS tools with a markup, we build systems from scratch or from open-source components. One-time implementation cost, minimal maintenance costs. You keep full ownership.

Websites with AI

We build fast, modern company websites and landing pages with a built-in AI chatbot, forms and automatic lead handling. No off-the-shelf WordPress templates here — every site written for a specific goal.

  • AI chatbot integrated into the site (no SaaS, own hosting)
  • On-page SEO: Schema.org, Open Graph, hreflang, Core Web Vitals

Web Applications with AI

We write full web applications — from login panel to complex business logic. Frontend (React / Next.js), backend (Node.js / FastAPI / Python), database (PostgreSQL / MySQL / Redis) — all tied together with an AI assistant inside.

You can use our infrastructure or deploy on your own server. You get full access to the code, without lock-in to any ready-made platforms.

  • React / Next.js — fast, responsive frontend
  • REST API / GraphQL — solid backend in Python or Node.js
  • AI assistant embedded in business logic (not as a chat, but as an engine)
  • User authorisation, roles, permissions
  • Integrations with ERP, CRM, payment APIs (Stripe, Przelewy24)
  • Docker + CI/CD — deployment on your VPS or cloud

Mobile Apps iOS & Android

We build native and cross-platform mobile apps with built-in AI — voice assistant, image recognition, content personalisation. One codebase, both platforms (React Native / Expo).

AI Voice Assistant

Built-in voice support using OpenAI Whisper (transcription) and GPT-4o (response). Works offline or on-device for selected models.

Image Analysis & OCR

Take a photo of a document, receipt, or label — the app automatically extracts the data and processes it without manual entry.

AI Push Notifications

AI decides when and what to send the user based on their behaviour — personalised notifications without rigid rules.

Content Personalisation

AI learns user preferences and adapts content, element order and recommendations — without hard-coding rules.

App Store & Google Play

We help with developer account setup, certificates, descriptions and graphics. We handle the technical side of publishing.

React Native / Expo

One codebase for iOS and Android. Faster delivery, lower cost, easier maintenance. Native look and feel without compromise.

Approximate mobile app costs
Simple app (CRUD + auth + API): from 8 000 PLN
App with AI (voice, camera, personalisation): from 15 000 PLN
Mobile SaaS platform (marketplace, fintech): from 30 000 PLN

Custom System Integrations

Do you have several systems that don't talk to each other? We write dedicated connectors and microservices that synchronise data in real time — without no-code tools with limits and without paying per "task" in Zapier.

Everything runs on your server or our infrastructure. The code is yours. Maintenance cost is a few dozen PLN per month for hosting — not hundreds for a platform subscription.

  • REST API, webhooks, event queues (RabbitMQ / Redis)
  • ERP ↔ shop ↔ warehouse ↔ CRM — bidirectional sync
  • Automatic invoice, label and document generation
  • Email / SMS notifications on system events
  • Full logs and monitoring — you know what's happening with your data

AI Chatbot — own infrastructure

We build chatbots in Python / Node.js, deployed on your server or VPS. AI model (GPT-4o, Claude, Gemini, Llama locally) — your choice. Knowledge base from your documents, PDFs, FAQs.

Widget for your website, WordPress integration, embeddable iframe or standalone — as you prefer. You pay once for the implementation, then only for actually consumed API tokens.

  • RAG (Retrieval-Augmented Generation) on your documents
  • CRM integration — automatic lead saving
  • Multi-language support — including Polish
  • Conversation history in your database

AI Agents & Process Automation

Autonomous systems that independently execute multi-step tasks — without human supervision, without paying per "run" on an external platform.

Document processing agent

Receives emails with invoices, extracts data, validates and saves to the system. Zero manual work on routine document processing.

Email response agent

Classifies incoming queries, automatically answers simple questions, escalates complex ones to a human with a draft response ready.

Reporting agent

Daily gathers data from multiple sources, analyses deviations, generates a report and sends it to your inbox. No manual spreadsheet collection.

Quoting agent

Based on a client's enquiry, generates a ready PDF quote, calculates the price from the price list and sends it by email — without involving a salesperson.

Data monitoring agent

Watches KPIs in real time, detects anomalies and alerts the right people before a small problem becomes serious.

Custom agent

Describe your problem — we'll design an agent tailored to your process. Multi-agent architecture, tool-use, memory — full stack.

AI Document Processing

We build pipelines for automatic extraction and processing of data from documents — invoices, contracts, emails, forms. They run in the background 24/7, without human involvement in routine operations.

Everything hosted on your server or VPS — data never leaves your infrastructure. We can use a local LLM (e.g. Llama 3) if full privacy is important to you.
