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
Reduce wasted media spend by testing and refining ad creatives before launch. For brand marketers and creative teams producing ad campaigns before media spend, convert uploaded video, banner, social and OOH assets into reviewer-approved creative response reports with attention, emotion, hook and retention evidence. The benefit is a testable hypothesis, measured through accepted creative revisions per review hour and reduction in post-launch creative corrections; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect uploaded video, banner, social and OOH ad creatives plus campaign brief and target audience, then follow this sequence: 1. Upload video, banner, social and OOH ad creatives. 2. Test and refine creatives before launch. 3. Generate attention heatmaps showing likely first gaze and missed areas. Resolve uncertain cases with qualified reviewers, approve reviewer-approved creative response reports, and measure accepted creative revisions per review hour and reduction in post-launch creative corrections 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. One fixed ad format and licensed asset set; final creative judgment and media decisions remain with the marketing team. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve brand voice, source attribution, quotation accuracy and usage permissions. Marketing teams approve substantive changes and publication scope. One fixed ad format and licensed asset set; final creative judgment and media decisions remain with the marketing team. 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: One fixed ad format and licensed asset set; final creative judgment and media decisions remain with the marketing team. Implement one approved input format, a bounded representative case set and the first two task modules: upload video, banner, social and OOH ad creatives; test and refine creatives before launch. Support the third module with operator review: generate attention heatmaps showing likely first gaze and missed areas. 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
Brand-owned creative assets, authorized campaign briefs and permitted audience research sources. Cloud asset storage, design-file import/export and advertising platform destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Creative upload and brief, Analysis workspace, Client-ready report. Use a thumbnail gallery for assets, a large central preview with attention heatmap and emotion curve overlays, and a right-hand panel for scores, suggestions and comments. Let users compare variants side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant frame or line. Make the task-specific outcome reviewer-approved creative response reports visible beside its evidence, review state and value baseline.
