Descript comes with a number of great fonts by default that can help spice up your titles and Fancy Captions. However, if you need to use a specific font to stay consistent with your company's branding or you'd just like to try out a new style for your videos, Descript allows you to choose from Google's vast library of free fonts, or to import a custom font file that you have on your computer (for Pro and Enterprise users).
Fonts are drive-specific
After adding a custom font to a project, that font will be available for all members of the drive that project is stored on. If you are a member of multiple drives, you would need to add the font to a project in each drive.
Adding a Google Font
Google Fonts are free to users on any subscription to add to their drive. To add a Google Font, open the Clip Inspector, click the Font dropdown menu, and select + Add fonts to Drive.
If you know the name of the font you'd like to add, enter it in the Search for a Google Font... bar and select it when it appears in the dropdown menu. Then click Add to Drive.
If you don't know the name of the font you'd like to add or want to search for something new in the Google Fonts library, click the Browse Google Fonts button.
Importing custom fonts from your computer 
Pro and Enterprise users can also import custom font files from their computer directly into Descript. To do this, open the Clip Inspector, click the Font dropdown menu, and select + Add fonts to Drive. Next, click Choose a file..., select the fonts you'd like to import, and click Open.
Drag and drop files
You can also drag and drop your font files directly into the Add fonts window.
Descript will automatically detect whether a font is italic or not. Click the Pencil icon to change the italic categorization or rename the font if necessary.
Next, click the checkbox to verify that all users have rights to use the imported font, then click Add to Drive to import the font.
Supported font files
Descript can import both .TTF and .OTF files
