Nodes
Nodes are the fundamental building blocks of a flow in Lamatic. Each node serves a specific purpose, acting as a self-contained unit that processes input and produces output. This modular approach allows users to create complex flows by interconnecting various nodes.
What you’ll learn
- What Nodes are and how they fit into a Flow
- The main Node categories (Apps, AI, Data, Logic)
- How to choose the right Node for your use case
Prerequisites
- Basic understanding of Flows
How to think about Nodes
If a Flow is a “recipe”, then Nodes are the steps:
- Each node has inputs
- It performs one job
- It produces outputs that the next node can use
Node Categories
Lamatic organizes nodes into four main categories, each with a unique function in building flows:
| Category | Purpose | Examples | Method |
|---|---|---|---|
| Apps | Integrate third-party applications into workflow | Slack, PostgreSQL, Google Sheets | These nodes act as bridges, enabling data exchange and action execution between Lamatic and external services. |
| AI | Perform artificial intelligence operations | Vector operations, text generation, natural language understanding | AI nodes use machine learning models to process and analyze data, allowing for tasks such as sentiment analysis, text classification, or content generation. |
| Data | Manipulate and transform data | Indexing, chunking, filtering | Data nodes provide tools for structuring, organizing, and processing information, ensuring data is in the right format for subsequent nodes. |
| Logic | Control the flow of execution | Conditional statements, loops, custom code execution | Logic nodes allow for decision-making and branching, enabling dynamic, responsive flow based on specific conditions or criteria. |
How to choose the right Node
- Need to talk to another tool/app? Use an Apps node.
- Need an LLM or AI operation? Use an AI node.
- Need to clean/transform/store/search data? Use a Data node.
- Need conditions/branching/code? Use a Logic node.
Not sure what to pick? Start from your trigger and ask: “what’s the next step in my pipeline?” Then add the node that does only that step.
Here are the Nodes

Troubleshooting
- Can’t find a node: make sure you’re in the Flow Editor and click Add Node.
- Node requires credentials: check the node config panel for required connections (models/apps).
- Output doesn’t match expectation: run a test and inspect node outputs step-by-step.
