What are Nodes?

Nodes are the building blocks of flows. Each node performs a specific function, defines typed inputs/outputs, and can be composed to create reliable automations. Nodes are organized by capability so you can quickly find the right tool for the job.
The examples below showcase common nodes in each category. Many more nodes are available in the platform.

​
Data & Files

Data & Files nodes transform, extract, and generate content from files and data.
Example Nodes: File to Text, Text to File, Download File, Merge FilesWhat They Do:
  • Extract text from PDFs, Word docs, and other file formats
  • Generate files from text or data
  • Download files from URLs
  • Combine multiple files into archives
Use Case Example: Use OCR to extract text from scanned invoice images, read and parse invoice data (amounts, dates, vendors), then analyze for expense reporting.
Example Nodes: File to Base64, File to PathWhat They Do:
  • Convert files to Base64 encoding for API transmission
  • Get file paths for local file operations
  • Transform data formats for compatibility
Use Case Example: Convert an image file to Base64 to include it directly in API requests or email bodies.
Example Nodes: Overlay Image on PDF, Fill File Template, Fill Excel Template, PDF Form FillerWhat They Do:
  • Fill document templates with dynamic data
  • Add images, signatures, or watermarks to PDFs
  • Populate Excel templates with calculated values
  • Complete PDF forms programmatically
Use Case Example: Generate personalized contracts by filling a Word template with customer data, then convert to PDF with company logo overlay.
Example Nodes: Read Webpage, Make API RequestWhat They Do:
  • Scrape content from web pages
  • Call external APIs with custom parameters
  • Fetch data from web services
  • Integrate with third-party platforms
Use Case Example: Fetch product pricing from competitor websites, then call your internal API to update pricing strategy.
Example Nodes: Run CodeWhat They Do:
  • Execute custom Python code within flows
  • Implement complex calculations or logic
  • Use external Python libraries
  • Process data with custom algorithms
Use Case Example: Run a custom Python script to analyze sales data using pandas and generate statistical insights.

​
Logic & Control

Logic & Control nodes route, filter, and transform data to shape execution.
Example Nodes: ConditionWhat They Do:
  • Create if/then branching logic
  • Route data based on conditions
  • Filter items based on criteria
  • Make decisions using AI or rules
Use Case Example: Route support tickets to different teams based on priority: high-priority to urgent queue, others to standard queue.
Example Nodes: Filter List Values, List to Single Value, Single Value to List, Count List ItemsWhat They Do:
  • Filter lists based on conditions
  • Convert between single values and lists
  • Count items in collections
  • Aggregate and summarize data
Use Case Example: Filter a list of customer emails to find only those from gmail.com domains, then count how many were found.
Example Nodes: Join Paths, Extract from StructuredWhat They Do:
  • Merge multiple execution paths
  • Extract specific fields from JSON or objects
  • Synchronize parallel operations
  • Manage complex flow routing
Use Case Example: Run two API calls in parallel, wait for both to complete with Join Paths, then extract specific fields from each response.
Example Nodes: Combine Text, Extract Fields, Merge File and Text, Markdown to HTMLWhat They Do:
  • Concatenate multiple text strings
  • Extract structured data from text using AI
  • Combine file content with additional text
  • Convert markdown to HTML format
Use Case Example: Combine customer name, order number, and shipping address into a formatted tracking email body.

​
AI Processing

AI Processing nodes understand and generate content using language and vision models.
Example Nodes: Generate Text, Generate Fields, CategorizerWhat They Do:
  • Generate human-like text from prompts
  • Extract structured data from unstructured text
  • Classify content into categories
  • Complete forms or templates intelligently
Use Case Example: Analyze customer review text, categorize sentiment (positive/negative/neutral), and extract key product mentions.
Example Nodes: Interpret Image, Generate Image, Transform Image, Interpret AudioWhat They Do:
  • Analyze and describe image content
  • Generate images from text descriptions
  • Edit or transform images
  • Transcribe and analyze audio
Use Case Example: Process receipt images to extract line items, amounts, and vendor information for expense reporting.
Example Nodes: Agent, Web ResearchWhat They Do:
  • Perform multi-step reasoning tasks
  • Use tools and integrations autonomously
  • Research topics using web search
  • Execute complex decision-making workflows
Use Case Example: Research a company using web search, extract key information, check it against your CRM, and prepare a summary report.
Example Nodes: Summarizer, Smart Route, Enrich CompanyWhat They Do:
  • Summarize long documents or text
  • Intelligently route data to different paths using AI
  • Enrich company data with public information
  • Perform domain-specific analysis
Use Case Example: Read a lengthy industry report, summarize key findings, and enrich mentioned companies with revenue and employee data.

​
Integrations

Integration nodes connect your flows to external services and platforms. Each integration node requires authentication configuration and provides specialized functionality for its respective service. Common Integration Examples:
  • Communication: Send Email, Read Email, Slack, Teams
  • Storage: Google Drive, Dropbox, OneDrive
  • CRM: Salesforce, HubSpot
  • Productivity: Calendar, Tasks, Sheets
Use Case Example: When a new lead is added to Salesforce, automatically send a welcome email via Gmail and create a task in your project management tool.
Integrations have a dedicated section in the documentation. Learn more about available integrations and how to configure them.

​
Subflows

Subflows are reusable flows that function as single nodes within other flows. They encapsulate complex logic into modular building blocks, enabling you to build maintainable and scalable automation. Nodes Interface Key Benefits:
  • Reuse common logic across multiple flows
  • Simplify complex flows by breaking them into smaller components
  • Maintain consistency through centralized updates
  • Test and debug isolated functionality independently
How They Work: Subflows define their own inputs and outputs, just like regular flows. When used as a node in another flow, they appear with input connectors matching their defined inputs and output connectors for their results. Any changes to a subflow automatically propagate to all flows using it. Use Case Example: Create a “Customer Validation” subflow that checks email format, validates phone numbers, and looks up existing records. Use this subflow in multiple flows (signup, checkout, profile update) to maintain consistent validation logic.
Create a subflow by building a regular flow and marking it as reusable. It will then appear in your node catalog under the Subflows category.
