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 visual and audio signals.
Not "improve your CTA." We rewrite it for you. Specific edits, specific frames, specific copy changes.
Caption timing, font readability, color contrast, and on-screen text density — scored against platform best practices.
Any format, any platform. TikTok, Meta, YouTube, Instagram. Drop it in and we start scanning immediately.
Frame-by-frame visuals, audio waveform, caption sync, hook pacing, CTA placement — analyzed simultaneously in under 60 seconds.
A scored report with specific edits, predicted market performance, persona fit, and rewritten copy suggestions ready to act on.
No per-seat nonsense. Pay for what you actually use.
