Request received

Thank you. Your request is in.

We are setting up trials in the order requests arrive. When yours is ready, we will email you with access and setup instructions. There is nothing else you need to do until then.

SemanticsBusiness definitions written as semantic views in Semantic SQL. The engine runs them and checks every join, so the same question gets the same answer.
KnowledgePlans, playbooks and notices stored as typed, linked, versioned entities. Agents find them by words, by meaning, and by following links.
MemoryWhat agents learn from earlier work, stored and searched the same way as knowledge.
TracesEvery model call and tool call, including what each step read and which version. Query them in SQL, next to your business data.
EvaluationsScores tied to the runs they judge, so you can compare answers over time and follow a low score back to its cause.
