Score Your Reel's Hook With Claude and Higgsfield Before You Post
TL;DR
Higgsfield's Virality Predictor is a free tool that watches a clip of up to 15 seconds and gives back a virality score, an engagement score, the exact second your hook peaks, a hold rate and a brain heatmap. You can connect Higgsfield to Claude Code through MCP and run it from your chat. Record a few hook takes, score each one and post the one with the best hold rate. The score is a modeled estimate and not a promise of views.

The Virality Predictor is a free Higgsfield tool. You give it a clip up to 15 seconds long, vertical or horizontal, and it sends a modeled audience through the clip. Then it shows you how that audience's brains react across vision, sound, memory, attention and language.
You get five readouts: a virality score, an engagement score, the exact second your hook peaks, a hold rate (how long people keep watching) and a heatmap of which brain regions your clip fires.
What the Virality Predictor gives you: a score for your hook before anyone sees it. The app page lists the price as 0 USD, and coverage of the launch calls it an experimental preview that uses no credits. You can try it on the website first with one clip.
Step 2: Connect Higgsfield to Claude Code
MCP is a standard way to let Claude use other apps. Higgsfield has an MCP server, and Claude Code is one of the clients it lists. Once it is connected, you can ask Claude to run the Virality Predictor without opening a separate site.
How to connect Higgsfield: copy the address below, paste it into Claude Code, and say: add this MCP server for me.
repo URLhttps://mcp.higgsfield.ai/mcpOr connect it by hand. Claude Code adds a remote server with this command. Then type /mcp inside Claude Code and log in to Higgsfield in your browser.

Record the first 15 seconds of your reel three different ways. Different opening line, different first frame, same idea. Then score all three and compare.
Prompts to try with the Virality Predictor:
promptUse the Higgsfield virality predictor on this clip: [path to your clip]. Show me the virality score, engagement score, the second my hook peaks and the hold rate, and tell me in plain words what the heatmap says.promptHere are three hook takes of the same reel: [path to take 1], [path to take 2], [path to take 3]. Run the Higgsfield virality predictor on each one, put the scores in a small table, and tell me which take to post and why.The honest catch
- The score is a modeled estimate. Higgsfield says no tool can guarantee a viral video. Treat the number as a way to compare your own takes, not a promise of views.
- The clip limit is 15 seconds. You are scoring your hook and opening, not a whole long video.
- Your idea still decides the result. A strong hook on a weak idea still loses. Score the hook after you have a good idea, not before.
Which way to start
- Want to try it once: open the Virality Predictor page and upload one clip.
- Post reels every week: connect Higgsfield to Claude Code and score three takes every time.
- Not sure your hook works: score your last reel's first 15 seconds and see where the hook peaks.

Common questions
Is the Higgsfield Virality Predictor free?
The app page lists the price as 0 USD, and coverage of the launch describes it as an experimental preview that uses no credits. Check the page before you use it, because Higgsfield can change that.
How long can the clip be?
Up to 15 seconds, vertical or horizontal.
What does the Virality Predictor show me?
A virality score, an engagement score, the exact second your hook peaks, a hold rate and a heatmap of which brain regions your clip fires.
Does a high score mean my reel will go viral?
No. Higgsfield calls the score a modeled estimate and says no tool can guarantee a viral video. Use it to compare your own takes.
Do I need Claude Code to use it?
No. You can use the Virality Predictor on Higgsfield's website. Connecting Higgsfield to Claude Code through MCP lets you run it from your chat.
