Important This page documents TinyMCE 5. For new projects, Tiny recommends using the latest, most up-to-date version. [See TinyMCE 8 documentation](../../latest/spelling/).
# Spelling options

## Spell Checker Pro

TinyMCE Spell Checker Pro is a premium feature that allows spell checking as-you-type and custom dictionary words.

For more information, see [Check Spelling As-You-Type](../check-spelling/) in the Premium Features section.

## `browser_spellcheck`

This option configures TinyMCE to use the browser’s native spell checker.

`browser_spellcheck` is not available in either Internet Explorer 8 or 9, as neither browser has native spell checker functionality. For more complete browser support, we recommend using [Spell Checker Pro](../introduction-to-tiny-spellchecker/).

**Type:** `Boolean`

**Default Value:** `false`

**Possible Values:** `true`, `false`

```js
tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  browser_spellcheck: true
});
```
For more information about spell checking in TinyMCE, see [this page](../spell-checking/) in the General-configuration-guide/ guide.

## `gecko_spellcheck`

> **Note:** Gecko Spell Check was deprecated in TinyMCE v4.3 (consider using [browser_spellcheck](#browser_spellcheck)). This option will be removed in TinyMCE 6.0.
This option allows you to disable [Gecko](https://en.wikipedia.org/wiki/Gecko_(software)) based browsers' internal spell checker from being used in TinyMCE.

**Type:** `Boolean`

**Default Value:** `true`

**Possible Values:** `true`, `false`

### Example: Using `gecko_spellcheck`

```js
tinymce.init({
  selector: 'textarea',  // change this value according to your HTML
  gecko_spellcheck: false
});
```
