Pick a layer. Set your filters. Let the font surprise you.
Font pairing is a lot of trial and error, clicking through the same ten typefaces because they're the ones you remember. Font Randomiser breaks that loop.
Select a text layer, and it assigns a font to it, but not blindly. Set filters for what you're after: weight, style, category, whatever narrows it down to fonts you'd actually use, and it randomises within those bounds. You get variety without losing control.
Less scrolling through dropdowns. More finding fonts you wouldn't have picked yourself.
