Analyze your hook

Upload your Short (MP4 or MOV). We analyze the first 5 seconds to help creators improve what is not working in their video opening.

Analysis usually finishes in under a minute. During busy times (many users running analyses), it can take longer — feel free to keep this tab open in the background.

Privacy note: uploaded videos are used only for analysis and are automatically deleted after processing. We do not store your video files.

    How it works

    Three steps from your Short to a clear virality score and tips.

    Content creation

    1 First 5 seconds

    We only look at the hook — the part that decides whether viewers stay or scroll. Video, audio, and on-screen text.

    2 Trained on real data

    Our model is trained on thousands of fitness Shorts: what actually got likes, comments, and reach vs what flopped.

    3 Actionable feedback

    You get a virality score plus plain-language tips — pace, lighting, motion, presence — so you can improve before posting.
