Preview content before it goes live

Before content goes live, you can preview it — and even check how it will look on a specific real screen, using that screen's actual properties and environment.

Quick preview (in the browser)

Generate a preview link for any content item to review it in your browser without publishing. Use this to sanity-check a new upload, an outpainted image, a Canva import, or a template before adding it to a playlist.

Context-aware check against a real device

For a more realistic test, evaluate content against a specific device (by its identifier). impressBox then considers that screen's real properties — and, where available, a photo of its actual environment — to assess how the content will read in place:

• a quality score with strengths, weaknesses, and concrete recommendations,

• in either a professional assessment or a playful roast tone,

• optionally emailed as a report.

This is the closest thing to "see it on that exact screen, in that exact spot" without travelling there. It's especially useful for screens in bright or unusual environments, where contrast and text size matter.

Recommended flow

1. Preview the item in the browser to confirm it renders correctly — ask the agent, e.g. “give me a preview link for this item.”

2. Evaluate against the target device to catch readability/context issues.

3. Fix or re-shape the content if needed (e.g. outpaint, larger text).

4. Add to the playlist, publish, and verify it reached the screen.

5. Optionally request a device screenshot to confirm the final on-screen result.
