description: Leverage Chrome AI to use LLM directly on your device

Send a prompt to the AI model built into Google Chrome (Gemini Nano) and get its reply, all on your device.

## What it does

Chrome AI is a standalone node, not a model you plug into an agent. It sends **Prompt** to Chrome's built-in model and returns the answer as `{ result }`. Nothing leaves your computer, there is no API key and no cost.

**Chrome only.** The node uses the AI built into Google Chrome, which Google is still rolling out (see [Chrome's built-in AI](https://developer.chrome.com/docs/ai/built-in)). It does not work in Firefox; there, use an on-device model from [Local models](/app/local-models/) or a cloud AI provider.

## When to use it

* Short, private text jobs: rewrite a sentence, pull a name out of a paragraph, draft a one-line reply.
* Workflows that must work offline or must not send text to a cloud service.

For longer or harder tasks, a cloud model behind [Basic LLM Chain](/nodes/builtin/ai/aiagents/basicllmchainnode/) gives better answers. For other on-device models, see the [Local AI](/nodes/builtin/ai/localai/) nodes.

## Inputs and settings

Without options, **Temperature** is 0.5 and **Top K** is 40. Lower values give more focused, repeatable answers; higher values give more varied ones. Use expressions in **Prompt** to include data from earlier nodes, for example `Summarise in one sentence: {{ $input.text }}`.

## Outputs

Each output item has these fields:

```json title="Shape of an output item"
{
  "result": null
}
```

`result` holds the model's reply as text.

## Dependencies and credentials

None. This node needs no connection and has no slots for other nodes.

## Example workflow

1. A [Context Menu](/nodes/builtin/trigger/contextmenu/) trigger on selected text.
2. Chrome AI with **Prompt** `Rewrite this politely: {{ $input.selectionText }}`.
3. [Clipboard Write](/nodes/extension/clipboardwrite/) copies `{{ $input.result }}`.

## Common issues

* **It fails with "only works in Chrome".** You are in Firefox, which has no built-in AI. Switch to an on-device or cloud model.
* **The model is not available.** Chrome's built-in AI is not enabled or not downloaded yet on this computer. Follow Google's setup steps for Chrome's built-in AI, then try again.
* **The run was stopped and there is no reply.** **Stop** cancels the answer while the model is still writing.
