What we analyze

Deeper than any tool on the market.

GoMarble looks at your ad account data. HookLens looks at the actual creative — second by second.

🎯
Frame-by-Frame Hook Analysis
We identify the exact second your viewer disengages. Not just "weak hook" — but frame 2.4s where your pacing stalls.

🔊
Audio Intelligence
Voice tone, music tempo, speech pacing, background sound — analyzed against what actually converts in your target market.

🌍
Geographic Fit Score
Cultural cues, language register, visual norms — we score which countries this ad will perform in and why.

👤
Persona Detection
Who is this ad actually speaking to? We extract the target persona purely from visual and audio signals.

✂️
Specific Fix Suggestions
Not "improve your CTA." We rewrite it for you. Specific edits, specific frames, specific copy changes.

📐
Caption & Visual Sync
Caption timing, font readability, color contrast, and on-screen text density — scored against platform best practices.
