Build complex AI without getting boxed in
Multi-step quote graphs, document roles, CAD in the browser. Swap how a node thinks without rebuilding the floor process around it. Author a component when the palette is not enough.
Lehrling now has made the canvas for engineering workflows open source — currently in beta. Join the waitlist.
Turn your shopfloor operations into unified visual workflows. Lehrling handles the repetitive checks—your experts keep total control over every call.

Use AI agents to solve problems that they are actually good at.
Multi-step quote graphs, document roles, CAD in the browser. Swap how a node thinks without rebuilding the floor process around it. Author a component when the palette is not enough.
Kai watches the desk and the floor. Knowledge stays with the part, not in a slide deck. Use the hosted demo today; shop-owned deployment is the point of a pilot.
Give Analyze Documents a role and an expected output. Keep estimators on the cost model. Inspect every execution: the file, the prompt shape, and what Kai returned.
Short feedback loops that keep quoting and programming in flow.
Case studies
RFQ → first-pass quote
“The canvas is the unlock. Chat is useful, but PathCraft is what lets you put CAD, documents, and cost on one path you can actually explain.”
Estimating lead · precision job shop
Session → shop memory
“Kai sitting beside the CAM session is how the next person gets the why — not just the toolpath file.”
Programming manager · mold & die
Enterprise-ready
Deploy the way a shop actually buys software. Watch agents without losing control of the quote.
Invite-gated demo, signed-in sessions, shop data stays in your conversation and files — not scraped into a public model card.
Canvas status on every live node. Document analysis you can re-run. Chat history you can read.
Drag-and-drop graph, custom components, CAD and LLM nodes in the same editor.
Role prompts, expected-output contracts, human markup on cost. Kai does not silently ship a number.
“I don't want another black-box copilot. I want to see the graph that priced the part.”
“Dropping the STEP on the canvas and watching features land is the first time AI felt like a junior on my bench.”
“The role field on Analyze Documents is the whole product. I tell it to be a quality engineer. It behaves like one.”
“We don't have time to train. If it can't learn while we quote, it doesn't get on the floor.”
“Custom nodes mean I'm not waiting on a vendor roadmap for fixture planning.”
“Cost model next to CAD is how quoting should have worked ten years ago.”
Join the shops building AI automation they can actually explain — on the canvas, not in a prompt graveyard.
