HOW IT WORKS

We run quick experiments on your first second—then keep the winners.

  1. 1

    Pick a hypothesis

    Example: “Earcon + warm steam > silence + cool condensation.”

  2. 2

    Shoot 2–3 A/Bs

    We build openers across sets: macro texture, steam/condensation, foley, color‑temp, overlay, beat, caption.

  3. 3

    Post both

    Post A now and B about 24h later (same caption/thumbnail). At 48h we review 1‑sec hold (primary), 3‑sec, watch time, saves—then plan your next hooks.

Quick FAQ

What is an “earcon”?

A tiny sound (like a “pop” or “click”) in the first second that grabs attention. We give you one that fits your clip.

What is “1‑second hold”?

The % of viewers still watching at 1.0s. Bigger % = stronger hook. We also peek at 3s, watch time, and saves.

Do I have to share data?

No. Services work without research. If you opt in, we only keep anonymous settings and the “A vs B” difference.

What is “implied‑sensory”?

Visual + audio tricks that hint at touch/temperature/scent/taste (e.g., steam, condensation, close‑up texture, fizz + foley).
