The Tools and Freebies pages use a Divi Slider module with custom layouts added via shortcodes.

To edit the contents in each 'Tab' visit the Divi Library and look for the layouts titled Tools Slide - XXXX and Freebies Slider - XXXX. There are 3 layouts for each page.

The titles for each of the 'Tabs' are set using Javascript and can be edited on the actual pages themeselves. Open up the fullwidth code modules and you will see the following code:

Tools Page:

<script>
(function ($) {
    $(document).ready(function () {
        $(document).bind('ready ajaxComplete', function () {
            //Replace the controller numbers with text
            $(".ds-tools-slider .et-pb-controllers a").html(function () {
                return $(this).html().replace('1', `Build <mark class="ds-tools-slider-heading">Start on the right foot<mark>`).replace('2', `Manage <mark class="ds-tools-slider-heading">Let's get things automated</mark>`).replace('3', `Grow <mark class="ds-tools-slider-heading">It's time to scale</mark>`);
            });
        });
    });
})(jQuery);
</script>

Freebies Page:

<script>
(function ($) {
    $(document).ready(function () {
        $(document).bind('ready ajaxComplete', function () {
            //Replace the controller numbers with text
            $(".ds-tools-slider .et-pb-controllers a").html(function () {
                return $(this).html().replace('1', `Plan <mark class="ds-tools-slider-heading">You've gotta have a plan<mark>`).replace('2', `Brand <mark class="ds-tools-slider-heading">Let's make you look good</mark>`).replace('3', `Build <mark class="ds-tools-slider-heading">Get that idea online</mark>`);
            });
        });
    });
})(jQuery);
</script>

To change the titles you need to edit the text after the numbers and between the <mark> tags, for instance:

For the Tools page, edit Build and Start on the right foot to change the text for the first tab, Manage and Let's get things automated to change the text for the second tab, and so on.

The same applies for the Freebies page.

If you make a mistake and remove something you shouldn't simply copy the code above and paste it into your code module and start again. Be sure to only edit the text indicated.
