Stop guessing.
Start isolating.
VoltKnot is the troubleshooting copilot for industrial electrical and controls teams. Turn a symptom, a measurement, and a machine history into the next safe test.

The VoltKnot method
A fault has a shape. Find it faster.
Every incident becomes a legible path from symptom to resolution — with the reasoning visible at each turn.
Make it safe
Control power, isolate energy, and surface the checks that come before a measurement.
Follow the signal
Rank likely causes, then sequence tests with an expected result for every branch.
Leave a record
Turn the fix into a reusable report your next technician can trust at 2 a.m.
The details between “it failed” and “it’s fixed.”
VoltKnot keeps the context that generic chat loses: equipment identity, control logic, measurements, recent changes, and the decisions behind the repair.
QR-linked manuals, wiring notes, network details, known faults, parts, and repair history.
Company procedures and proven fixes, organized so local expertise travels with the crew.
Clear stop points when a test is unsafe, inconclusive, or ready for engineering support.
After the repair
Every solved fault makes the next one less mysterious.
Capture the test results, parts, cause, and escalation notes as a service report your team can search, share, and build on.

Scan the machine.
Bring the right history, diagrams, and known faults to the point of work.
