Understand unfamiliar PLC projects in hours, not days.
Humerus reconstructs program structure, machine behavior, I/O relationships, and engineering context—then lets engineers investigate the project with AI.
Turn undocumented PLC projects into engineering knowledge.
Humerus AI is an intelligent assistant built for industrial PLC environments. Our long-term vision is AI that observes, interprets, and interacts with PLC software the way human engineers do — through the screen. Until vision-only AI is mature enough, today we deploy a lightweight client on the customer's engineering PC that automatically captures and uploads PLC project data, with analysis and chat running in the cloud. We are steadily working toward a future with no integration and no on-site footprint.
A lightweight client today, cloud AI at work, zero integration as the end state.

From project understanding to engineering action
Humerus begins by understanding the PLC project itself—its structure, logic, signals, dependencies, and machine behavior. From that foundation, Humerus is evolving toward AI-assisted investigation, debugging, and interaction with engineering software.
Why Humerus AI
Industrial control systems suffer from a persistent problem:
Legacy PLC programs without documentation
Lost design intent and engineering context
Time-consuming debugging and logic tracing
Increasing maintenance complexity across multiple devices
Humerus AI directly addresses these challenges by transforming opaque PLC projects into structured, explainable, and maintainable systems.
Focus on innovation and not reverse engineering old logic.
Key Advantages
Lightweight Local Connector
A lightweight local Connector interacts safely with your engineering environment. Our long-term goal is zero integration.
PLC-specialized AI
Built on domain-specific models and industrial knowledge
Flexible Deployment
Online Experience
Cloud analysis for evaluation, pilots, and accessible project review.
Private / On-Premise Deployment
Planned for organizations with stricter project-data and network requirements.
Project-Grounded Intelligence
Analysis is built around the actual structure and evidence of the PLC project rather than generic AI responses.
What Humerus AI Does
1. Understand PLC Projects
Automatically reconstructs:
- Control logic
- Program structure
- Variables
- IO relationships
- Process flows
Turns undocumented legacy programs into structured engineering knowledge.
2. Analyze Control Logic
Deep inspection of PLC programs to detect:
- Logical conflicts
- Redundant logic
- Dead code
- Timing issues
- Potential risks
Helps engineers investigate problems faster and identify potential issues earlier.
3. Recover Engineering Knowledge
Rebuilds lost design intent from existing code:
- Design intent
- Functional architecture
- Engineering relationships
- Missing documentation
Turn tribal knowledge into accessible engineering context.
4. Ask Humerus AI
Ask questions about:
- Blocks
- Variables
- Networks
- Logic
- Process behavior
- Analysis findings
Evidence-based answers grounded in your project — not guesswork.
