Extension Catalog
The extensions below are the ones in active use today. Each entry carries an honest status: Bundled ships inside every install, Available is published to the public extension feed and installable per deployment, and In build is under active development and not yet released.
This catalog reflects what actually ships. Capabilities under development are listed as such — we publish direction, not promises dressed as features.
Bundled with the application
Systems Engineering workbench — Bundled
A dedicated systems-engineering surface in the activity bar, hosting
workbooks and Assistant chat for SE work. It also makes ontology files
first-class citizens: Turtle (.ttl) documents open in a dedicated viewer
with a readable source pane and a rendered class diagram view, including
cardinality from OWL restrictions. This is the shell that systems-modeling
and methodology capabilities grow into.
Ontology — Bundled
Makes ontologies something you manage, not just store. Its centerpiece is the ontology steward — an agent that walks you from a vocabulary need to a published ontology: co-designing a small domain vocabulary in chat, pausing at an explicit agreement gate, then publishing through the same gated, verified workflow all graphs use. It also carries the working methods (skills) for graph naming, versioning, provenance, and ontology lifecycle practices such as validation shapes and pinned imports. Works out of the box against the built-in graph service; connecting an external triple store extends where it can publish. See Managing Ontologies.
Available from the extension feed
Jupyter Notebooks — Available
Full Jupyter notebooks inside Insight LM: open and edit .ipynb files, run
cells against a real Python kernel in the app-managed environment (no local
Python setup), and let the Assistant author and execute notebooks as part of
answering a question. Includes notebook templates and a Notebooks view in
the workbench. This is the computation engine described in
Notebooks, and the most mature extension in the
feed.
Insight Sheet — Available
A spreadsheet inside the workbench. Create and edit sheet documents with an Excel-like grid and formula engine, kept inside the workbook alongside the data and documents they refer to — so calculation work stays part of the record instead of drifting off into detached files.
SysML v2 — Available (early)
Systems modeling on two fronts. Today it ships a connector to a SysML v2 REST server — create projects, run diagnostics, import requirements, and publish conceptualizations from inside Insight LM — plus the beginnings of a modeling workbench: a semantic model tree with properties and requirements lenses over a local model graph. The extension defines a constrained, machine-readable subset of SysML v2 that the Assistant can work in reliably. The workbench half is expanding release by release.
Fuseki connector — Available · optional
Connects Insight LM to an external Apache Jena Fuseki triple store: manage datasets, test connections, and run SPARQL queries and updates, with explicit gates on credentials and destructive operations. Off by default, and never required — the built-in graph service covers core graph capabilities; this connector is for teams that already run shared RDF infrastructure.
Neo4j connector — Available · optional
The same pattern for property graphs: connect to an external Neo4j database, inspect its schema, and run Cypher queries, with a read-only mode and gates on administrative operations. Off by default, never a dependency of core features.
The feed also carries a set of smaller utility extensions (PDF tools, analysis helpers, data connectors, dictation) that follow the same rules.
In build
SysML Lite — In build
A lightweight, graph-first systems-modeling capability growing inside the SysML v2 extension: the model is a file-based graph in the workbook, the Assistant works as a first-class modeler through structured methods, and edits reload live. Early workbench pieces already ship in the SysML v2 extension above; the guided modeling capability is in active development and its shape is still moving by design.
