Output — unretouched

Also checked on this input — same tool, 5 other criteria

Ad-readiness⚠ StruggledBecause the background is generic and the app interface is absent, the export would need further production work before paid-ad use.Avatar realism⚠ StruggledThe presenter still looks AI-generated compared with higher-end tools, so the avatar does not fully pass as a natural human creator.Product understanding⚠ StruggledThe output uses a generic background and omits the app UI, so it does not strongly communicate the mobile-app product itself.Script quality & persuasiveness⚠ StruggledThe delivery feels slightly flat and would need more energy to be strongly persuasive.Voice quality✓ WorkedThe voice output stays consistent throughout the ad.
