# Overview

> See how Snaply's AI Writing Assistant rewrites, fixes grammar, translates, and polishes text in any Mac app with fast local AI.

**Select text. Press the shortcut. Get a better version back.**

The [Writing Assistant](/writing-assistant/overview) is Snaply's text layer: select something, open the assistant, choose a [mode](/writing-assistant/modes), and either replace the text instantly or keep working in chat.

It is built for fast edits inside your existing workflow, not as a separate writing destination you have to live in.

Snaply is designed for fast, local-first editing. Use the built-in model for private rewrites, or switch to [cloud models](/writing-assistant/cloud-models) when you want OpenAI, Anthropic, Google Gemini, OpenRouter, xAI, Groq, Mistral, or an OpenAI-compatible endpoint.

## How It Opens

Most people use one of these entry points:

* Select text and press `Control + Space`
* Select editable text and click the assistant icon near the selection
* Open the Writing Assistant page in Snaply and review recent edits

If nothing appears, open **Settings -> Writing Assistant** and make sure **Show Writing Assistant** is enabled.

## What It Is Great At

* Fix grammar without changing the meaning
* Polish tone, clarity, and formatting
* Translate into a target language
* Run a saved custom mode for repeated tasks
* Switch into chat for follow-up instructions

## Instant Fix Or Follow-Up Chat

| Workflow        | Best for                                                     |
| --------------- | ------------------------------------------------------------ |
| Instant replace | grammar fixes, quick rewrites, predictable formatting        |
| Chat            | follow-up instructions, refinement, more open-ended requests |

<Note>
  You can enable **Show on non-editable text** if you want the assistant to appear even when the selected text cannot be replaced in place.
</Note>

## History

Snaply keeps a local history of recent transformations inside the app.

That means a good rewrite does not disappear the second you move on.

From **Writing Assistant -> Recent Edits**, you can:

* Reopen a previous conversation
* Copy or reapply a result
* Rerun a transformation with a different mode
* Delete old items
* Select multiple recent edits and delete them together

## Privacy

With the built-in local model, selected text stays on your Mac.

That local-first setup is the easiest way to keep Writing Assistant fast, private, and available inside your normal Mac workflow.
