Everything You Need in One Workspace
From AI-powered code intelligence to version control and deep analysis — PLC Forge brings modern software engineering tools to the controls world.
AI That Actually Understands PLC Code
Not a generic code assistant. PLC Forge's AI agent is built for controls engineering — it understands PLC semantics, tag structures, and industrial automation patterns.
Explain
Ask the AI to summarize routines, trace tag usage, and break down unfamiliar code.
Modify
AI-assisted refactoring and edits with full context awareness of your project.
Generate
Describe what you need in plain language and get working, standards-compliant code.
PLC Semantics
Understands data types, AOIs, tag scope, and program structure — not just text.
Git-Native Change Tracking, Built In
Track every change to your PLC project with real version control. No more saving copies as "Project_v3_final_FINAL". No external tooling or CLI required.
- Visual diffs — see exactly what changed between any two versions
- Full commit history with search and filtering
- One-click rollback to any previous version
- Remote repositories for backup and collaboration (Pro)
