Nodes are the building blocks of every workflow. Each node is a single step that does one job, and you connect nodes with edges to form the automation. You add a node by dragging it from the sidebar onto the canvas.
AI Workflow Automation ships around two dozen node types, grouped into six categories in the node sidebar.
The six categories
Core
- Trigger starts the workflow. It can fire manually, from a form submission, an inbound webhook, a WordPress event, an RSS feed, or another workflow. See Trigger Nodes.
- Output ends a branch by displaying, saving, or sending the result (display, database, HTML shortcode, webhook, Google Sheets, or Google Drive). See Output Node.
AI Actions
- AI Prompt (the AI Model node) sends a prompt to OpenAI, Anthropic, or OpenRouter and returns text, or named typed fields when you turn on structured output. See AI Model Node.
- AI Research runs deep web research with Perplexity Sonar models.
- Write an Article drafts a full article to a target length.
- AI Summary Generator condenses text.
- AI Sentiment Analysis scores tone, which pairs well upstream of a Condition.
- AI Extract Information pulls named fields (single values or lists) out of unstructured text.
- AI Optimize for SEO rewrites content for search.
Data Processing
- API Call makes an HTTP request with auth, retries, and JSONPath extraction.
- Web Scraper (Firecrawl) scrapes, crawls, maps, or searches the web.
- Connect an App brings Google, Slack, Notion, GitHub, and thousands of other apps into a workflow as action steps.
- Document Parser reads a document from a URL or upload.
Logic & Control
- Condition branches to a true or false path using AND/OR groups.
- Loop / While repeats steps over a list or until a condition is met.
Content & Media
- Create Post/Product creates or updates posts, pages, custom post types, WooCommerce products, and ACF fields.
- Create File writes a TXT, DOCX, or HTML file to the media library.
- Generate PDF renders a PDF from a template or your own HTML.
- Media Generator creates images, video, or audio from the live Fal.ai catalog.
- Unsplash Image finds a stock photo.
Communication
- Chatbot deploys an AI agent chat widget trained on your data. See Chat Node.
- Human Input pauses the workflow for a person to review, edit, or approve.
- Send Email sends an email with a rich or plain body, Cc/Bcc, and attachments.
Free nodes and credit costs
Every node type is free in Local mode: you run on your own server with your own API key, and you pay your AI provider directly for model usage. When a workflow runs in Cloud mode, each node consumes platform credits. Trigger, Output, Condition, Loop, Human Input, Create Post, and Document Parser cost zero credits even in the cloud, while heavier nodes cost more (for example, Media Generator and AI Research are the most expensive). See Execution and Scheduling and Cost Management.
A few nodes are Local-only or Cloud-only
- Local-only: Chatbot, Create File, Unsplash Image, and the Google Sheets and Google Drive outputs run only in Local mode.
- Cloud-only: Generate PDF runs only in Cloud mode.
If a workflow contains a Local-only node, the Cloud toggle explains that it cannot switch to Cloud until you remove that node.
