VidCognition vs Brainsight
Brainsight predicts where attention lands on a frame. VidCognition watches your ad and tells you which segment is losing viewers, then rewrites the hook for you.

Bottom line
Brainsight provides AI-predicted attention heatmaps for static and video frames. VidCognition answers a different question: not where the eye lands, but why a viewer would keep watching, returned as a timestamped written critique with rewritten hooks. Neither tool predicts what an ad will earn, and VidCognition says so on its own pages.

VidCognition sends the actual video to a vision language model prompted to behave like a senior paid-social strategist reviewing a cut before it goes live. It comes back with Hook, Bridge and Offer scored separately, a written breakdown of what happens in each segment with timestamps, one to five specific fixes, and rewritten hook lines.
Paid plans also render a simulated brain-response curve from Meta's TRIBE v2 research model as a secondary panel. It is labelled directional in the product and the score is not derived from it. The score comes from the critique.
Brainsight uses AI saliency models to predict visual attention — where a viewer's eyes are likely to fixate on a given frame. It is primarily designed for design and UX work rather than short-form video ad review, and it does not return a written critique, scored hook, or rewritten hook lines. For layout and visual hierarchy questions that is the right shape of tool.
