Getting started
Sign in to Chat, choose sources, and make your first query.
Cortex Chat helps you find life cycle datasets, check their applicability, and discuss LCA questions. Sign in to Chat and choose New Task, or continue a conversation from the sidebar.
First use
New accounts without conversation history or an existing profile can choose their role, industry, current focus, and LCA experience. Expand Other when the choices do not fit. You can go back to revise a choice or skip a step.
Review your choices and decide whether to save them to your profile. Fill in example puts an editable question in the composer; it does not send it. You can change or remove the example.
Choose sources
Use the database button below the composer to select databases, versions, and system models. You can select multiple versions of a database. Available system models update with the selected versions.
Selecting a commercial database does not grant access to its values. See Databases and data access.
Describe the query
Write the product, intended use, process, and region in Chinese or English. For example:
Find LLDPE granulate production data for material inputs to plastic film production, preferably for China.
If you need a finished product, name it rather than just its material. Cortex may ask for missing conditions; returned candidates still need checking.
Read the results
Candidates and dataset links appear in the conversation. Open a link to check the product, region, unit, system model, and description. Values that are restricted or could not be read cannot be used as calculation inputs.
Continue with Reading search results, Profile and answer preferences, and Conversations and sharing.
