The page designer app is part of Airtable Apps, a Pro plan feature. Apps let you extend the functionality of your bases: you can use apps to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
With the page designer app, you can create your own custom invoices, business cards, catalogs, real estate feature sheets, casting sheets, and more—all using the data directly from your records. When you're done making everything look beautiful, you can print out your records or turn them into PDFs.
