Ad-readiness◐ MixedThe clip is understandable and usable in principle, but the neutral tone, generic background, and AI-obvious presenter keep it from feeling fully ready to launch as-is.Avatar realism◐ MixedProduces a believable talking-head presenter, but the report still describes the avatar as moderately AI-generated compared with higher-end tools.Product understanding✓ WorkedUnderstands a language-learning app well enough to position it around short lessons, daily practice, and simple, fun learning.Script quality & persuasiveness◐ MixedKeeps the script simple and clear, but the emotional tone stays neutral, so the promo is serviceable rather than especially compelling.Voice quality✓ WorkedGenerates a stable voice performance that remains consistent across the clip and fits the educational-app style prompt.

AKOOL✗ FailedAdds no app UI or other product footage at all.HeyGen✗ FailedThe supporting footage is not product-integrated because the cutaway uses the wrong app entirely, so the B-roll does not match the Duolingo testimonial being spoken.Invideo AI◐ MixedThe clip adds a timed phone-and-coffee cutaway, but the screen content is blurred and generic instead of product-specific, so the supporting footage does not fully reinforce the app.JoggAI✗ FailedThe tool can produce a single static shot with no cutaways and no product visuals, so the app never gets any supporting footage.Topview AI⚠ StruggledThe podcast-style output does not show the Duolingo app UI, so the ad lacks contextual app integration.VEED⚠ StruggledThe Duolingo output is a talking-head clip, and the report says the Duolingo UI was not automatically included, so contextual app visuals were not supplied by default.
