Plain + Blueprint Nexus
Connect Plain to your knowledge graph
Plain becomes part of the 1,400+ tools that connect to Blueprint Nexus. Rather than sitting in its own silo, Plain connects its datasets, models, and pipelines to the decisions and documents that explain them. Its datasets, model runs, pipelines link to your notes, tasks, and goals in one associative graph — searchable from a single bar, with governed AI agents reasoning over the connected whole. Credentials stay in your encrypted vault, with BYOK supported.
