LemvaneThe AI-native machine engineering platform Private preview
Brief in. Tested machine out.

AI that designs, programs and tests your machine before it is built.

Describe a custom machine in plain words, or bring your CAD and I/O list. Lemvane's AI agents lay out the machine, write the IEC 61131-3 control program and run it against a simulated twin, fault cases and e-stop included.

Private preview for invited engineers.

Numbers from one run on our test bench, 11 Nov 2026, about five and a half minutes from brief to passing program. The animation redraws that machine.
One run, six stages

Every stage is checked before the next one starts.

  1. 01

    Brief

    Plain words, a sketch, or your project documents: parts lists, specs, an I/O list.

  2. 02

    Machine description

    Stations, devices and signals, with every number you gave kept as stated.

  3. 03

    Tests first

    The requirements of the brief get their tests before any CAD or code is written.

  4. 04

    CAD

    Parts and layout, checked for reach, strokes, clearances and motor side.

  5. 05

    PLC program

    Structured Text as a real multi-file project, one object per file.

  6. 06

    Simulated tests

    The program drives the twin through each scenario until every test passes.

Who it is for

Builders of custom machines.

Material handling and assembly

Conveyors, pushers, clamps, presses, labelling and robot cells.

Engineers stay in charge

Every stage, check and test result is shown, with the reasons.

Your documents count

Parts lists and specs in the project; their numbers are kept like the brief's.

Coming soon

Test your own PLC code

Run a program you already have against the simulated machine.
