# Interkey Brain > The complete industrial PLC. AI-native control system in one cabinet — controller, I/O, HMI, vision, and AI agent. EU AI Act-aligned. Forever license from €2,500. Replaces SCADA, HMI vendors, and integration projects. Interkey Brain is a vertically integrated industrial control platform combining hardware (controller, I/O modules, status display, NVIDIA Jetson AI co-processor) and software (Brain OS, IEC 61131-3 PLC engine, HMI builder, AI agent, vision system) in a single cabinet. The user describes a machine in plain language — heaters, sensors, PID targets, safety limits — and Brain's AI agent generates the control program, builds HMI screens, configures alarms, and runs simulations. Direct competitors: Siemens TIA Portal + Eigen, Rockwell FactoryTalk + Studio Copilot, Beckhoff TwinCAT + CoAgent, CODESYS + MCP, Schneider EcoStruxure. Differentiators: forever license (€2,500 / €5,000) instead of annual maintenance; air-gapped capable; 5-tier AI safety model; Python plugin SDK and MCP server; EU AI Act-aligned with full audit trail. Industries: food & beverage (freeze dryers, breweries), building automation (HVAC), manufacturing (packaging, conveyors), pharma & defense (air-gapped). Launch customer: WAVE Trockensysteme (Austria, freeze dryers). ## Product - [Pricing](https://www.interkey.com/pricing.md): Brain Core €2,500, Brain Pro €5,000, Brain Vision Pack €990.
