What it does
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.
Upload any video ad. HookLens scans it frame by frame , analyzes the hook, audio, captions, and body — then tells you exactly what to fix and which markets it'll convert in. GoMarble looks at your ad account data. HookLens looks at the actual creative — second by second. We identify the exact second your viewer disengages. Not just "weak hook" — but frame 2.4s where your pacing stalls. Voice tone, music tempo, speech pacing, background sound — analyzed against what actually converts in your target market. Cultural cues, language register, visual norms — we score which countries this ad will perform in and why. Who is this ad actually speaking to? We extract the target persona purely from…from hooklens.net
