The problem

Teams refresh creative without knowing whether fatigue explains changes.

What it gives you

Analyst-reviewed refresh decision report

What you give it

Approved creative historiesaggregate outcomes

How it works, step by step

  1. Separate exposure cohorts
  2. Test bounded refresh hypotheses
  3. Compare observed contribution
  4. Compare the reviewed result with the recorded baseline and value assumptions
  5. Capture corrections and named-owner approval before consequential use
  6. Export a versioned analyst-reviewed refresh decision report with source references and unresolved questions

Questions

Do I need to know how to code?

No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.

What does it cost?

The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.

How long does it take?

The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.

Can I change it to fit my business?

Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.

More detailsHow the AI works, safeguards and what to build first

Spend production effort where a tested refresh helps

Confirm the buyer's problem and scope, collect approved creative histories and aggregate outcomes, then follow this sequence: 1. Separate exposure cohorts. 2. Test bounded refresh hypotheses. 3. Compare observed contribution. Resolve uncertain cases with qualified reviewers, approve analyst-reviewed refresh decision report, and measure incremental contribution minus new creative and test cost against a documented baseline.

How the AI works

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Do not treat correlation as causation; no automatic campaign edits. A model suggestion is never a verified fact, professional decision or authorization to act.

Safeguards

Verify product claims and permissions. Distinguish observed campaign results from causal explanations and keep customer data collection authorized. Do not treat correlation as causation; no automatic campaign edits. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.

What to build first

Pilot scope: Do not treat correlation as causation; no automatic campaign edits. Implement one approved input format, a bounded representative case set and the first two task modules: separate exposure cohorts; test bounded refresh hypotheses. Support the third module with operator review: compare observed contribution. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.

What it can connect to

Approved brand material, campaign exports and authorized customer research. Read-only business data exports, reporting databases and task trackers. Reconcile source totals before scheduling recurring data refreshes. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.

The screens in detail

Primary screens: Data and definitions, Pattern investigation, Action and value review. Open with a compact overview and filters for the relevant period or segment. Let users drill from each theme or metric into underlying records. Keep source definitions and missing-data notes near the result. Use an action panel to assign investigations and record what was learned. Make the task-specific outcome analyst-reviewed refresh decision report visible beside its evidence, review state and value baseline.
