Text Node

The Text Node is a fundamental utility node that stores and outputs static or dynamic text content. Unlike Display Text which shows content to users, the Text node works behind the scenes to provide text data to other nodes in your workflow. It's essential for supplying prompts, instructions, queries, and other text-based inputs to processing nodes like AI prompts, API calls, and data operations.

Text Node

Basic Usage​

Use the Text Node to store text content that will be passed as input to other nodes, such as AI prompts, web searches, API calls, or any node requiring text input.

Inputs​

The Text node does not accept inputs from other nodes. It serves as a source node that provides text output to subsequent nodes.

Outputs​

Output (Green Port)​

Text Content: Outputs the text content stored in the node.

  • Connects to green input ports of other nodes
  • Passes the exact text from the Output field
  • Can connect to multiple nodes simultaneously
  • Text is passed as-is without processing

Configuration​

Output Field​

Text Content Area: Large text box where you enter the text content to be passed to other nodes.

Features:

  • Multi-line text input
  • Plain text (no Markdown rendering)
  • Supports variable interpolation using labels (e.g., {{USERNAME}}, {{SCORE}})
  • Scrollable for long content
  • No character limit

Example Content:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. 
Praesent rutrum, massa vel feugiat scelerisque, ipsum elit...

Encrypt the Text​

Security Option: Checkbox to encrypt the text content stored in the node.

When to Enable:

  • Storing sensitive information (API keys, passwords, credentials)
  • Personal data that requires protection
  • Confidential instructions or prompts
  • Data subject to privacy regulations

When Disabled:

  • Regular text content
  • Public information
  • Non-sensitive prompts and instructions
  • Content that needs to be easily editable

Example Workflows​

AI Prompt with Text Node​

Scenario: Provide a system prompt to an AI processing node.

Text Node Example

Steps to Create the Flow:

  1. Add a Start Node.

  2. Add a Text Node:

    i. Configure the Output field:

    You are a helpful biology tutor. Explain complex concepts 
    in simple terms that a high school student can understand. 
    Use examples and analogies to make the content engaging.

    ii. Leave "Encrypt the text" unchecked (not sensitive content)

  3. Add an AI General Prompt node:

    • Connect: Text node Output (green) → AI General Prompt "Overwrite System Prompt" (green)
    • Configure other AI prompt settings as needed

  4. Add Display Text node to show results:

    • Connect: AI General Prompt Output → Display Text Input

Preview:

[Start] → [AI General Prompt]
              ↑ (System Prompt from Text Node)
       → [Display Text: Show AI Response]

Result: The AI uses the custom system prompt from the Text node to generate responses in the specified style.

  • Display Text: Shows text to users (Text node provides backend text)
  • Create Text Label: Creates variables that Text node can reference
  • Text Join: Combines multiple Text node outputs
  • AI General Prompt: Receives prompts and instructions from Text node
  • Web Search: Receives search queries from Text node
  • API Call: Receives endpoints, headers, and payloads from Text node
  • Multi-Turn Conversation: Receives instructions from Text node
  • Local LLM Connector: Receives prompts from Text node

Text Node vs Display Text Node​

FeatureText NodeDisplay Text Node
PurposeBackend data supplyUser-facing display
VisibilityNot shown to usersShown to users
OutputText data onlyText display + data
FormattingPlain textMarkdown support
Use CasePrompts, queries, dataMessages, instructions
ConnectionGreen port onlyGreen + Red ports
EncryptionOptionalNot available

When to use Text Node:

  • Supplying prompts to AI nodes
  • Providing queries to search nodes
  • Storing API parameters
  • Backend configuration
  • Data that shouldn't be displayed

When to use Display Text:

  • Showing messages to users
  • Displaying instructions
  • Presenting results
  • User-facing content
  • Formatted text with Markdown

Security Considerations​

Encrypting Sensitive Content​

Always encrypt:

  • API keys and tokens
  • Database credentials
  • Authentication information
  • Personal identifiable information (PII)
  • Proprietary algorithms or methods

Example:

Text Node: "API_KEY=sk-1234567890abcdef..."
✓ Enable "Encrypt the text"

Best Practices​

  1. Principle of Least Exposure: Only store sensitive data when absolutely necessary
  2. Separate Credentials: Use dedicated Text nodes for sensitive data
  3. Regular Audits: Review which Text nodes contain sensitive content
  4. Access Control: Restrict who can edit flows with encrypted Text nodes
  5. Rotation: Update encrypted credentials regularly

Summary​

The Text Node is a versatile utility for supplying text data throughout your workflows:

✓ Simple: Easy to configure and use
✓ Secure: Optional encryption for sensitive data
✓ Flexible: Supports variables and multi-line content
✓ Efficient: Instant processing, no overhead
✓ Reusable: One node can supply multiple targets

Master the Text node to create maintainable, organized workflows with clear separation between data supply and user display.
