Text Shot is a universal (iOS/iPadOS/macOS) application that lets you take text snippets and create beautiful shareable images (text shots).
You can add a title, source, author, and the quote, or just a few of them!
From there, you can choose a theme, font, and a size, to customise how each text shot looks.
You can also find all of this functionality inside of a "Create Text Shot" action in the Shortcuts app. Which means, you can even build your own automations to make the process of creating and sharing your text shots even easier.
