# Core concepts

> The vocabulary NoClick uses: workflows, nodes, edges, runs, credentials, credits, organizations, and templates.

A short glossary of the terms you'll see throughout NoClick and these docs.

## Workflow

A graph of connected nodes on the canvas. It can be an automation, an AI agent setup, a web app, or all three at once. You build workflows visually or by describing them to the [AI builder](/builder/overview). See [The canvas](/editor/canvas).

## Node

A single unit of work in a workflow. Nodes fall into a few categories:

| Category    | What it does                                                       | Learn more                             |
| ----------- | ------------------------------------------------------------------ | -------------------------------------- |
| Trigger     | Starts a run: schedule, webhook, form, inbound email, or app event | [Triggers](/triggers/overview)         |
| Integration | Talks to an external service like Slack, Google Sheets, or Linear  | [Integrations](/integrations/overview) |
| Logic       | Controls flow: branching, loops, filters, delays, approvals, code  | [Branching](/logic/branching)          |
| Interface   | A block in your app's UI: forms, text, uploads, custom components  | [Interface blocks](/apps/blocks)       |
| AI agent    | An LLM with tools that reasons across steps and integrations       | [AI agents](/agents/overview)          |

See [Configuring nodes](/editor/configuring-nodes) for how to set a node up.

## Edge and data references

An edge connects two nodes and carries data from one to the next. Inside a node's config you reference upstream outputs (for example, a field from the previous node's result) by dragging them in or typing a reference. See [Data references](/editor/data-references).

## Run

One execution of a workflow, started manually, by a trigger, or via the API. Each run records every node's inputs and outputs so you can replay it later. See [Running and testing](/editor/running-and-testing) and [Execution logs](/editor/execution-logs).

## Credential

A stored connection to an external service: an OAuth login, an API key, or a custom OAuth client. Nodes reference credentials instead of holding secrets in their config. See [Connecting accounts](/credentials/connecting).

## Credit

NoClick's usage unit. 1 credit equals \$0.25 of underlying provider cost. Credits cover things like AI tokens on NoClick's keys and AI builder generations; runs on your own credentials and keys are free. See [What costs credits](/billing/costs).

## Organization

A shared workspace for a team. Members collaborate on the same workflows, and organization runs bill the owner's credit pool. See [Organizations](/collaboration/organizations).

## Template

A published workflow others can browse and fork from the template gallery. See [Using templates](/templates/using).
