GPT-5.6 Creator Coach reviewing campaign requirements
Inspiration
Social-media creators—both new and established—need genuine opportunities to work with businesses. At the same time, businesses need authentic ways to introduce their products and services through creator videos.
These partnerships are often managed through scattered messages and informal agreements. Businesses struggle to find suitable creators and communicate campaign expectations, while creators struggle to discover opportunities, understand requirements, submit their work, and track approvals and payments.
We created Promo Zone AI as a structured marketplace where businesses and creators can collaborate throughout the entire promotional campaign process.
## What it does
Promo Zone AI connects businesses with emerging and established social-media content creators.
Businesses can publish campaigns containing the product or service, preferred platform, target views, payout, number of creators required, brand mentions, hashtags, content instructions, and restrictions.
Creators can:
- Discover published campaigns
- Review campaign requirements
- Apply for suitable opportunities
- Create videos featuring the product or service
- Submit content and performance proof
- Track approval and payment status
Businesses can review applications, select creators, evaluate submitted content, approve campaign proof, and release payouts through a structured workflow.
Campaign Architect, powered by GPT-5.6, helps businesses turn basic product information, campaign goals, target audiences, platforms, and brand tone into editable creator-ready briefs. It suggests content concepts, instructions, hashtags, success signals, and important guardrails.
Creator Coach uses GPT-5.6 to review a creator’s proposed hook, caption, voice-over, or video script against the campaign’s actual requirements. It identifies missing mentions, hashtags, deliverables, unsupported claims, and other risks, then suggests an improved draft and practical shot list.
AI provides recommendations, but businesses remain responsible for publishing campaigns, choosing creators, approving submissions, and releasing payouts.
## How we built it
The mobile application was built with Flutter, Dart, Riverpod, and GoRouter. Laravel provides the production API and manages authentication, user roles, campaigns, creator profiles, applications, submissions, approvals, uploads, wallet holds, payouts, and ledger-backed transactions.
Laravel communicates with the OpenAI Responses API using GPT-5.6 and Structured Outputs. This provides predictable, typed results that the mobile application can display as editable campaign briefs and creator coaching feedback.
We designed the AI features so that user-provided campaign information is treated as untrusted input. Business-controlled values such as payouts, target views, creator counts, platforms, publishing decisions, approvals, and payments cannot be changed by the model.
The OpenAI API key remains on the server and is never included in the Android application.
Codex helped us audit the existing codebase, research the APIs, design the AI architecture, implement structured-output schemas, write tests, diagnose Android build issues, verify the application on an emulator and physical device, and prepare the deployment and submission documentation.
We started with an existing marketplace baseline and added the GPT-5.6 Campaign Architect and Creator Coach workflows during Build Week.

## Challenges we ran into
The biggest design challenge was introducing useful AI assistance without allowing AI to control sensitive marketplace actions. We separated generated recommendations from authoritative business and financial data so that humans remain responsible for every important decision.
We also worked through Android manifest-merging conflicts, device CPU architecture differences, authentication-session handling, API response timeouts, and testing across an Android emulator and a physical Android device.
Another challenge was ensuring that Creator Coach evaluated drafts against the specific campaign instead of producing generic marketing advice. We solved this by providing the published campaign requirements and authenticated creator context to GPT-5.6 through a strict structured workflow.
## Accomplishments that we're proud of
We built two practical GPT-5.6 features inside a working two-sided creator marketplace rather than creating a standalone AI demonstration.
Businesses can create and publish campaigns, while creators can discover opportunities, apply, submit content, and participate in an approval and payout workflow.
Campaign Architect preserves business-controlled campaign values while generating an editable creative brief. Creator Coach provides campaign-aware recommendations without making approval or payment decisions.
We also deployed a live production API, produced a public Android build, tested the application on real devices, kept the OpenAI secret server-side, and published the source code with documentation and an MIT license.
## What we learned
We learned that AI is most valuable in a marketplace when it improves communication and preparation without replacing human authority.
Structured Outputs made GPT-5.6 responses easier to validate and safer to integrate into the application. We also learned that testing only in development is insufficient: emulator, physical-device, authentication, networking, and release-build testing revealed issues that were not visible during normal coding.
Codex was especially useful as a development partner across the complete lifecycle—from understanding the codebase and implementing features to testing, deployment, troubleshooting, and release preparation.
## What's next for Promo Zone AI
Next, we plan to add:
- A dedicated required-video-duration field
- Creator performance and campaign analytics
- Better creator discovery and matching
- Multilingual campaign briefs and coaching
- Reusable business brand profiles
- Creator identity and consent verification
- Mobile Money and additional payout integrations
- Campaign messaging and negotiation tools
- Smarter recommendations based on creator niches and previous performance
Our long-term goal is to make promotional partnerships accessible to creators at every experience level while giving businesses a transparent and organized way to manage creator-led marketing.
