LCA Graph (Beta) invitation only
This is an experimental service. It uses an AI model to draft a complete process model for LCA Model, the finished tool, from a flowsheet you upload and the data you supply: the units and streams, the parameters with their sources, the equations for mass balance, inventory, impacts and costs.
- The draft is checked by the same calculation engine that runs the published case studies, so it cannot contain undefined quantities or circular logic. It can still contain a wrong number. Every draft must be reviewed by a person before it is used.
- What you upload is sent to a third-party model provider (OpenRouter) to produce the draft. Do not upload anything confidential during the beta.
- Access is by invitation while the service is in beta. Each code has a daily limit.
No code? Ask us for one. The public, AI-free LCA Model with four verified case studies is here.
Draft a model from a flowsheet
Upload a flowsheet picture. The model reads the units and the streams between them, then drafts the whole PML document: parameters with sources, mass balance, inventory, impacts, costs and cash flow. The draft is compiled and solved in your browser; compiler errors go back to the model for repair, up to five times. The standard model is cheap; a stronger one is one click away if it keeps failing.
Anything you leave out is assumed by the model and flagged as an assumption in the draft.
