Seemlessly integrates with Rockwell Studio 5000 IDE. Fully trained for Allen Bradley ControlLogix, CompactLogix, and GuardLogix series.
Engineers inherit undocumented PLC programs from a former employee who retired three years ago. Some may call it “job security”
The new engineer is tasked to upgrade the production line. They're tracing contacts backwards through dozens of subroutines to find the interlock that is stopping the pump.
This is days of work that should take minutes.
PLC Copilot fixes this in minutes
Actual questions automation engineers ask every day, answered against IEC 61131-3 projects with thousands of rungs.
Point PLC Copilot at your existing project file. The AI looks at the relevant rungs, tags, and subroutines to answer your questions.
No syntax. No query language. Ask it the way you’d ask the engineer at the next desk.
Pump_2 is held OFF by an interlock at Rung 847.
Safety input I:3/12 (E-Stop bank 2) is de-energized. The latch on B3:4/2 will not clear until E-Stop is reset and Start_PB is pressed.
Answers cite the rungs, tags, and subroutines involved. Review the suggestions made by PLC Copilot and apply them to your project.
Not another wrapper. PLC Copilot has been vigourously trained to understand IEC 61131-3 programs. It can read your rungs, cross-reference tags, and explain your controller settings to give you back the time you lose tracing them.
Upgrading a legacy system requires understanding exactly how it behaves. Tracing thousands of rungs and tags can take days, if not weeks.
PLC Copilot turns the legacy logic into human-readable explanations in seconds so you can map the old behavior into modern architectures without guesswork.
You can run multiple PLC Copilot instances in parallel, each working independently on a different plant, line, or migration project.
Whether you’re starting a new project and need to brainstorm control strategies, or you want to offload repetitive build work, PLC Copilot can generate the logic.
Use AI drafts for common patterns, repeated interlocks, and routine scaffolding, then review each rung, tune it to site constraints, and adapt it directly into your project standards.
Auto-write rung comments, structured tag tables, input/output mapping, control narratives, subroutine summaries, and the supporting detail teams usually leave until the end of the job.
Review in bulk, tighten wording where it matters, and keep documentation aligned with the revision you’re shipping, not a stale export from last year.
Export as CSV for spreadsheets, tag lists, and row-oriented handoffs, or as plain text for submittals, SOPs, FAT/SAT packages, and narrative blocks you can paste into any template.
Offline and on-prem options are only available for enterprise plans. The online plans send chunks of your request to our servers where it is processed. See our Privacy Policy for more details on how we protect your proprietary information.
Ladder logic is proprietary. Often under NDA. Nobody, not even us, can view or execute your source in context.
The AI works in an isolated local environment, communicating over an encrypted channel. Ensuring that your code remains private and secure.
Some teams prefer to use their own servers, some can't connect to the internet at all. We can accomodate your needs in our enterprise plan.

PLC Copilot is trained to understand all and every PLC program, regardless of the vendor. We're rolling out support for more vendors one at a time to ensure the best possible experience.
“ I commend you on this PLC Copilot. It just saved me a boat load of time trying to figure out how someone else's undocumented spaghetti works. Where in the past I would have probably trashed it and rewritten, now I can document the program so others can benefit. Thank you! ”
Real scenarios from beta users. Names withheld, facts real.
The engineer who wrote it retired in 2019. I had two weeks before the audit. I ran Copilot across the whole routine on a Monday, reviewed the generated rung comments the same afternoon.
Asked Copilot why process was stuck. It pointed at a latched interlock tied to a guard-door input that was stuck low. Swap a proximity sensor, line back up in 40 minutes.
The goal was to get new hires up to speed as soon as possible without burning weeks from someone else's calendar. Even veterans used to hit the same wall when trying to decode someone else's code. PLC Copilot acts as a patient companion available on demand, answering foundational questions so new hires can get up to speed quickly.
We spent years commissioning lines and debugging logic on concrete floors. We know the pressure when a line is down and every minute counts.
Automation has zero room for error. We built Forge because we needed a tool that understands industrial logic, respects the risk of a real plant floor, and actually helps you get the job done faster.
