Create encounter-scale maps suited to virtual tabletops like Roll20 and Foundry VTT, or for printing.
Generate maps at quality suitable for print and detailed on-screen use.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
