Unfortunately, there is no default option to translate products and categories automatically in Magento. You need the Magento 2 Translation Extension and it's various integrations to make it possible.

Once you set up Magento Google Translate Integration or other AI engines you'll have multiple auto translation options.

Auto Translate in Menu

The simplest way to auto translate products and categories in Magento, just hit the Auto Translate button at the page top menu.

Auto Translate in Form and Popup

Use Auto Translate option for all or separate fields in the translation pop-up.

Auto Translate Schedule

The last option to translate products and categories in Magento is the Translation Schedule. Just navigate to Stores > Configuration > Magefan Extensions > Translation > Auto Translation > Schedule Translation and select the product and categories.

Magefan Translator will schedule the translation and automatically translate and update the translation (if any) for your catalogue pages.
