Sapient reads how a real human brain responds to your content, second by second. Below are the most common ways teams put that to work, in plain language: what you’re trying to learn, what to submit, and which model fits.
Rule of thumb: use Mary for text or mixed content, and Qualia when you’re comparing videos.

​
A/B testing ad creatives

Compare two ad variants and see which one actually holds attention and drives purchase intent, before you decide where the budget goes.
  • Submit: each variant as its own scan, then compare the timelines.
  • Model: Qualia when the variants are visual (different cuts, footage, pacing). Mary when they differ in script or voiceover.
  • Look at: the attention and purchase intent curves side by side, to see which one stays higher, longer.

​
Hook analysis & optimization

The first three seconds decide whether anyone keeps watching. Find exactly where the hook lands and where attention drops off.
  • Submit: the creative (reel, TikTok, ad). Model: Mary for any content; Qualia for purely visual hooks.
  • Look at: the per-second attention curve over seconds 0–3, plus the moments block for the first flagged drop.

​
Creator content pre-post check

Score a reel or TikTok before you publish it, so you ship the version that performs.
  • Submit: the finished cut. Model: Mary (it reads everything: visuals, voice, captions, and pacing together).
  • Look at: the overall score and grade for a fast verdict, then the timeline to tighten weak seconds.

​
Pre-flight QA before ad spend

Before you put real budget behind a creative, sanity-check it the way a focus group would, instantly.
  • Submit: the creative. Model: Mary by default; Qualia when you’re choosing between visual variants.
  • Look at: the headline score, the attention and purchase intent lenses, and the moments where it slips.

​
Script / voiceover testing

Compare copy or voiceover variants line by line, without filming anything.
  • Submit: the script as text, or the voiceover as audio. Model: Mary. This is exactly where Mary is sharpest.
  • Look at: the per-second attention and purchase intent curves to see which lines land and which lose the reader.

​
Manipulation & brand-safety check

See how heavily a creative leans on emotional persuasion versus plain reasoning, which is useful for brand-safety and compliance review.
  • Submit: the ad. Model: Mary (or Qualia for video-only).
  • Look at: the manipulation and emotion lenses across the timeline.

​
Memorability test

Attention is cheap; memory is what sells. Find out what actually sticks.
  • Submit: the creative. Model: Mary (or Qualia for video-only).
  • Look at: the memory lens. A high attention score with a low memory score means it grabs focus but doesn’t stay.
