## What information is sent to Mistral AI?

To get better results and maximize our chance to have a relevant answer from the AI, we send:

- your **post content **(if not possible your post URL),
- your **post language**,
- your **target keywords** (and we ask to put at least one of them in the SEO metadata in return).

Note that we can’t fully control the provided answers by Mistral AI.

## Enable Mistral in SEOPress

Go to **SEO**, **PRO**, **AI** tab.

Select **Mistral AI** from AI provider option.

Paste the key to **Mistral API key** field.

**Save changes**.

*AI settings – SEOPress PRO*

### Add my Mistral AI key to wp-config.php

By adding this code below:

`define( 'SEOPRESS_MISTRAL_KEY', 'XXXXXXX' );`

You will store your Mistral API key in your **wp-config.php** file instead of your database. This is more efficient on a multisite network for example but also more secured.

## Generate SEO and social metadata with AI

Now you have linked your Mistral AI account with your WordPress site, you can use AI to:

- [generate SEO metadata](https://www.seopress.org/support/guides/generate-your-seo-metadata-with-openai/#generate-your-title-and-meta-description-with-ai)
- [generate alternative texts for your media](https://www.seopress.org/support/guides/generate-alternative-texts-for-your-images-with-openai-and-seopress-pro/)

## Common errors

Quickly test your Mistral API key by going to **SEO**, **PRO**, **AI** tab.

Then from **Mistral** section, click **Test API key** button.
