Before the next edit round

What should your creative team receive?

A useful review connects a specific creative moment to a decision your editor can act on. Bring the original assets, audience, offer, platform, brand constraints and the question you need to resolve.

Keep: The passage, image or brand cue worth preserving, with the reason.
Change: The exact frame, timestamp or wording to revise; the proposed edit and its priority.
Explain: What is visible in the creative, what the model infers, and what remains uncertain. BuyerLens objections are simulated hypotheses.
Decide and test: Who accepts, adapts or rejects the recommendation, which version gets made, and what real evidence would support the next decision.

Why use SaliencyLab if we already use ChatGPT or Claude?

A general assistant can help review an ad when you provide the assets and context. SaliencyLab brings brand context, eligible market references, creative versions, diagnostics and recorded decisions together in a project. The review service adds a human-owned recommendation and revision review; a software subscription is a separate offer.

That workflow is a reason to evaluate the product, not proof of better advice. Compare the same assets and brief, check whether recommendations are supported and usable, and record the time your team needs to reach a decision. We have not completed an independent head-to-head quality study against ChatGPT or Claude.

Read the comparison protocol v2

Choose real participant research when you need actual buyer responses. Use a controlled campaign test for performance effects. Meta diagnostics remain directional, and BuyerLens cannot independently validate RoastIQ.

Start with the DTC testing guide or the agency buying checklist to match the evidence to your brief.

Two briefs. Different evidence needs.

A small DTC brand choosing the next edit

Bring the actual Meta or TikTok assets, target buyer, offer and campaign objective. Ask which opening, product explanation or brand cue deserves a revision, and what should stay intact.

SaliencyLab fits a team that can make the edits and wants annotated priorities with a human review. Meta diagnostics remain directional. If the decision requires actual buyer comprehension, recruit real participants; if it requires conversion performance, use a controlled campaign test.

An agency preparing a client recommendation

Agree the decision, audience, market and format before choosing a supplier. A client deliverable should distinguish what is visible in the creative, what a model suggests, what real participants said and what happened in market.

SaliencyLab fits revision planning and documenting the reasoning between edit rounds. Commission respondent research when the client needs measured audience responses or an established research framework. AI screening, including a competitor’s AI product, is a separate purchase from a new consumer study.

Asset limits, editing and workspace access

One image or one video up to 60 seconds. Each edit, language version or placement adaptation counts separately. Each cycle covers one campaign brief, one audience and one platform for one brand. Longer videos, additional markets or multiple brands receive a separate quote before work starts.

Your designer, editor or agency makes the changes. We provide annotated frames and priorities for the opening, sequencing, product visibility and benefit demonstration. Production, video editing and media buying are outside this review service.

The workspace access and analysis usage needed for the agreed review are included, with no additional software subscription required for that work. You receive downloadable deliverables to keep. Ongoing software use after the engagement requires a separate workspace plan; access and data-retention arrangements are confirmed in your proposal.

Read the full scope, revision and cancellation terms

Inspect the output before commissioning.

The CeraVe worked case shows the original creative, archived model scores, the evidence behind a proposed revision and an unexecuted test plan. It is an editorial analysis of a public ad, not a customer endorsement or an outcome study.

For the current report layout, inspect the seeded RoastIQ demo. Its demonstration numbers are not fresh measurements of a client campaign. A useful handoff connects an exact frame or passage to the proposed edit, the reason, the evidence limit and the next test.

Use real interviews for unexpected buyer language and cultural interpretation; a suitable quantitative study for population estimates; and controlled delivery for in-market effects. BuyerLens generates hypotheses downstream of RoastIQ and cannot independently confirm its score. No provider’s headline score is directly comparable without a common study.

SaliencyLab’s evidence boundary.

The platform-native attribute model is separate from RoastIQ’s five KPI scores. Its held-out estimates do not validate the composite or establish superiority over another provider.

ρ +0.33

TikTok click-through rate · held-out Spearman · n=691

+0.33 on TikTok click-through rate (n=691), held out. On the cohort its weights were tuned on the same model scores +0.43, brand-clustered 95% CI [+0.32, +0.53]

ρ +0.40

YouTube view counts · held-out Spearman · n=397

+0.40 on YouTube view counts (n=397), held out. On the cohort its weights were tuned on the same model scores +0.49, brand-clustered 95% CI [+0.37, +0.58]

No sales, ROAS, attributed-conversion or brand-recall prediction is claimed. Heatmaps predict visual attention; they do not measure eye tracking. BuyerLens generates synthetic resistance themes, not measured emotional strength or real participant responses.

Read the methodology and limitations

Questions before commissioning.

Does this replace research with real people?

No. Choose actual participant research when your question requires observed consumer responses. AI diagnostics and synthetic interviews provide different evidence.

How much does each cost?

SaliencyLab publishes a defined sprint and monthly review scope below. Ask the other provider for a current quote covering the exact product, audience, market and outputs. Software access and human review are separate commercial scopes.

How quickly can results arrive?

System1 advertises AI screening in minutes and consumer-test results from 24 hours. Availability depends on product and market. SaliencyLab automated analysis and human delivery are separate stages.

Is one more accurate?

No common held-out head-to-head study is presented here. Different targets, datasets and measures cannot be ranked from headline accuracy figures.
