Most creators post blind and optimise from comments and view counts days later. This tool closes that loop to minutes, letting you rewrite the weakest two seconds of your hook before anyone sees it.
Step 1: Open the Virality Predictor
Go to higgsfield.ai/apps/virality-predictor. No account required to run your first score. The interface accepts video clips up to 15 seconds.
Step 2: Upload Your Clip
Drop a clip that is 15 seconds or shorter. Aim for the opening segment of your reel rather than the full video, because the tool is built to evaluate hook performance specifically.
Step 3: Read the Score Breakdown
After processing, the tool returns four outputs:
- Viral Score — an overall likelihood rating for the clip
- Hook Score — how strong your opening moment is
- Hold Rate — predicted percentage of viewers who stay through the clip
- Brain-Region Heatmap — a visual map across five dimensions: vision, sound, memory, attention, and language, showing the exact timestamp where engagement starts to fall
Focus on the heatmap first. The drop-off point is your rewrite target.
Step 4: Rewrite the First Two Seconds
Use the heatmap to identify which brain region weakens earliest. If attention drops at second one, your opening frame needs more visual contrast or motion. If language scores low, your first spoken line or text overlay is not specific enough. Make one focused change, not five.
Step 5: Re-Score and Ship the Winner
Export or re-record the revised clip, run it through the predictor again, and compare scores. Ship the version with the higher hook score. Repeat this loop for each reel before posting.
Bonus: Run it Over MCP
If you are building an automated content pipeline, the tool works through Claude, Hermes Agent, or OpenClaw over MCP. You can wire a score check directly into your n8n workflow so every clip gets graded automatically before it reaches a scheduling node.
Why This Works
Human attention during the first two seconds of a short-form video is the single highest-leverage variable in algorithmic distribution. Tools that return structured, timestamped feedback let you act on a specific moment rather than a vague impression. Iterating on score deltas before posting compresses the feedback loop from days to minutes, which compounds over dozens of posts.
Pro Tips
- Test your thumbnail frame too. Run a static 15-second clip that opens on your thumbnail image to see how the vision score reacts before any motion starts.
- One variable per iteration. Change only the first two seconds between re-scores so you know exactly what moved the needle.
- Save every score report. Build a personal benchmark from your own clips so you know what score threshold actually converts for your specific audience and niche.
- Pair with MCP for scale. If you produce more than five reels a week, an n8n node that auto-submits new clips and logs scores to a Notion or Airtable database removes the manual step entirely.
