Spark starts immediately
Open a managed account, build a focused first model, and keep local file export available.
Self-serve Causal AI workbench
Darkstar Online
Build causal graphs, test interventions, and share decisions.
Build Bayesian-network models in the browser. Run evidence, interventions, counterfactuals, CPT sensitivity, and Studio influence-diagram policy or VOI analysis before sharing or SDK delivery.

- Runtime grants
Paid plans add persistence
Cloud documents, autosave, larger limits, sharing, and authenticated support unlock as work grows.
Runtime access is gated
Protected WASM grants tie inference access to the account and entitlement state.
Causal modeling
A dense decision surface for repeated analytical work.
Graph authoring
Build directed causal graphs, edit node states and probability tables, and keep layouts readable as networks grow.
Causal queries
Inspect evidence, posteriors, lift, interventions, and counterfactuals without leaving the workspace.
Sensitivity analysis
Rank which CPT entries move a target probability most, using the current evidence or intervention state.
Studio decision analysis
Studio adds influence diagrams, policy solving, expected utility, and value-of-information ranking.
Data sampling
Generate sample rows, test scenarios, export synthetic data, and inspect how assumptions move through the model.
Candidate structure learning
Cloud-native learning runs constraint, search-and-score, and optimization workflows from reviewed datasets in the same product surface.
Example models
Start from real network shapes.
The public model corpus gives users meaningful networks to inspect, query, and export before committing paid cloud storage.

Access follows the account.
Spark, paid plans, support credits, and commercial SDK licenses all resolve through the same account boundary, so product access stays explainable.
