TextBuddy isn’t meant for permanent text storage. It’s designed for quickly working with text and moving on.
But what if you do want to save your text more long-term? You have a few options.
You can of course copy and paste your text elsewhere. Or, you can use the “File” → “Export” command to save your text to a .txt file.
However, for super smart people who have Drafts.app installed, you can one-click send your text to Drafts.
