Anything App

Testing in Preview

The preview pane lets you test the version you are building before you publish it. Use it to catch issues early and iterate quickly.

What preview shows

Preview shows your app as it will appear after publishing, using the current version you are working on. After each Build prompt creates a new version, test the result in preview before continuing.

If you find a problem, describe it to the AI in Build mode and it can generate a fixed version.

Preview versus live app

Preview is a test environment. Data entered in preview is temporary and is not saved permanently.

The live app is the published version that you and your users access from the shareable link. Data entered in the live app is stored in each user's private database.

AI credit usage

AI features used in preview, including chat, image generation, and text analysis, consume AI credits from your account even though preview data is temporary.

Testing checklist

Before publishing, try to:

  • Walk through the main user flows from start to finish.
  • Test edge cases like empty states, long text, and invalid inputs.
  • Resize the preview pane to check different screen sizes.
  • Confirm AI features respond the way you expect.
  • Use Build mode to fix anything that is broken, confusing, or visually off.
