Hook. Body. CTA. Know exactly where your ad fails.
Most video ads fail silently. You spend money, get bad results, and have no idea why. HookLens watches your ad frame by frame, transcribes the audio, and delivers a full breakdown — hook score, body retention, CTA clarity, audio pacing, and a line-by-line script rewriter that shows your exact spoken lines with specific rewrites for the weak ones. Upload any video ad and get a downloadable client-ready report in minutes.
Agency and Pro plans offer bulk upload, team access, and up to 100 scans/month with API access, enabling teams to analyze dozens of ad variations quickly and generate client-ready reports at scale.
HookLens scores caption timing, font readability, color contrast, and on-screen text density against platform-specific best practices (TikTok, Meta, YouTube, Instagram), preventing technical issues that reduce ad performance.
HookLens scores geographic fit by analyzing cultural cues and visual norms, detects target persona from visual and audio signals alone, and predicts which countries the ad will convert in—helping users target the right markets.
HookLens scans uploaded video ads frame-by-frame to identify weak hooks, poor pacing, and CTA clarity issues, then provides specific rewrite suggestions and predicted market performance—enabling users to fix creative problems before spending money on ads.
The tool analyzes hook strength, body retention, audio pacing, caption sync, and CTA clarity with specific frame-level diagnostics (e.g., 'pacing stalls at frame 2.4s'), then delivers rewritten copy and edit suggestions rather than vague feedback.
