Our Unique Features
AI Virtual Assistant
Harness the power of AI to speed and improve the development of coherent and complete Causal Loop Diagrams
(CLDs) and simulatable models! Our brand-new AI Virtual Assistant allows you to connect to different
LLM-based AI engines, provide prompts, and receive results as both diagrams and simulatable models.
You can then analyze the results, and refine and edit them based on continued interaction with the AI engine.
The Virtual Assistant has been organized in a way that makes it easy to experiment with different queries to
improve your results.
Loops That Matter™
Introduced in 2020, Loops That Matter brings clarity to your simulation data. It lights up the most important
feedback loops, giving you a simple visual guide to the forces behind the behavior. This immediate understanding
of model behavior allows you to focus on the correct variables to create a robust analysis of the results.
Assemblies
Assemblies™ are self-contained models that
streamline the modeling process by serving as building blocks for other models. You can move from a blank
page to a simulating model in a matter of minutes. Assemblies are now also available in a special section
of the isee Exchange™ where users can share their custom assemblies and download others to their software.
Designs
Designs enable you to create sophisticated interfaces with consistent aesthetics and color palettes.
With a selection of styles that are fully customizable, you can go from blank page to professional presentation
in no time. You can even use them to create interfaces for your Vensim® models.
Storytelling
Storytelling gently introduces the model structure behind the interface by unfurling parts of the
model. Annotations explain what structure means and partial simulation reveals the structure's
implications for the model's behavior. Try a live demo here.
isee Exchange™ and Sharing
The isee Exchange is a repository of content created by Stella users around the world. You can easily
publish simulations or upload models and share them with others at no cost. Users can view and run
these simulations from any modern browser. Paid private hosting options include additional features
such as data collection or running large models with an added engine on our servers. The Exchange
can be found at https://exchange.iseesystems.com.
Our Newest Features
Data Manager on the Interface
This feature enables users to hide, show, delete, and rename runs, and to use the settings from
previous runs to create new runs. This makes it much easier to compare results across runs, manage
the amount of information displayed in comparative graphs and tables, and refine experiments.
Interface sections
Organize interface pages into sections, much like stories are organized. This makes it easier to navigate
during development and can be helpful when multiple people are working on an interface.
Custom shape tool
The Custom Shape (Model) tool allows you to place arbitrary shapes on a causal loop or model diagram to
highlight elements of the diagram. This makes it easier to present complex diagrams by breaking them up
into a number of visual components.
Connector enhancements
Connector labels increase the readability of diagrams, especially Causal Loop Diagrams.
The polarity symbol can also be set to appear in the middle of the connector rather than just at its head.
Variable values in text boxes and annotations
Insert variable values into text boxes and annotations by including a variable name and optional
time enclosed in ${}. The value of the variable will be displayed using the number formatting
options, including any number text mappings set up for the variable.
