Launch Variables & Global Variables

Learn the difference between global variables and launch variables in MindStudio workflows to tore data across runs or pass external inputs into an AI agents via API or automation platforms.

MindStudio supports two powerful types of variables that extend the functionality of your AI agents: Global Variables and Launch Variables. Each serves a distinct purpose and can help you build more advanced, persistent, and externally-driven workflows.

Global Variables

Global variables allow you to store values between workflow runs. This is useful when you want to retain state, keep a running record, or reference previous output in future executions.

Key Features:

• Prefixed with global.

• Stored project-wide and persist between agent runs

• Configurable from the Global Variables tab in the root project folder

Example: Story Generator

• A story-writing agent appends new chapters to a global variable called global.story.

• Each run checks if a story exists:

  • If it does: generates the next chapter.

  • If not: starts a new story.

• The story is stored and updated in the global.story variable.

• You can view and edit global variable values under the Global Variables tab.

This approach is ideal for accumulating content, maintaining histories, or building AI memory-like features.

Launch Variables

Launch variables allow you to inject data into your workflow at runtime, often via an external integration (e.g. API, webhooks, Make.com).

Key Features:

• Declared in the Start Block

• Replaces the need for user input blocks when running workflows programmatically

• Supports structured automation flows like onboarding forms, CRMs, or lead collection

Example: Sales Collateral via Google Form

• A Google Form collects company data (e.g. name, representative, company info).

• A Make.com automation sends these inputs into MindStudio as launch variables.

• The MindStudio workflow uses these variables to generate personalized sales content.

• The generated output is passed back and saved to a Google Sheet.

Launch variables streamline integrations and automate personalized content generation at scale.

Recap

Variable Type	Purpose	Persistence	Source
Global Variables	Save data across runs	Persistent	Internal (within MindStudio)
Launch Variables	Inject data from external systems	One-time use	External (via API or automation)

By using global and launch variables strategically, you can create more intelligent, dynamic, and automated AI agents in MindStudio.
