The Technical Challenge

We built an AI-powered Amazon appeal generation system using Retrieval-Augmented Generation (RAG) trained on 46 real, successful appeal templates. The system analyzes the specific suspension reason, maps it to the closest winning precedents, and drafts a tailored Plan of Action in minutes, not days. Deployed across 2,000+ appeals with an 87% reinstatement success rate.

  • Critical Bottleneck
  • Manual appeal writing took 3-7 days and cost sellers up to $3,500 per case, with inconsistent outcomes and no data-backed approach.
  • Business Risk
  • Every day of suspension costs Amazon sellers an average of $1,000-$10,000 in lost revenue, making speed and accuracy mission-critical.

The Implementation

Gemini-Powered RAG Pipeline

We indexed 46 real successful Amazon appeals into a vector database, building a proprietary precedent library that no off-the-shelf tool could replicate. When a seller submits their case details, Gemini semantically searches this database and retrieves the most relevant successful precedents. These are injected directly into the generation prompt, grounding every appeal in proven, real-world language that Amazon's review teams have already accepted. This single layer is the primary driver behind the platform's 87% success rate.

GPT-4o-mini Generation Engine

The core generation layer uses OpenAI GPT-4o-mini with a custom-engineered legal prompt system built specifically for Amazon's reinstatement framework. It structures every appeal according to Amazon's own preferred format, Plan of Action, Root Cause, Corrective Steps, and dynamically adapts tone and emphasis based on the specific violation type, whether that's an inauthentic complaint, a policy breach, or a performance-related suspension. The result is a fully formatted, professional appeal document delivered in under 3 minutes.

Admin Prompt Engineering Panel

Behind the seller-facing product sits a full internal admin dashboard that gives the team complete control over the AI's behaviour. Prompts can be iterated and versioned, legal templates managed and updated, and A/B tests run between document variants to compare approval rates across different writing approaches. Every change is tracked and logged, turning what is usually a guesswork-driven process into a measurable, data-backed discipline.

Stripe-Gated Seller Portal

Sellers access the platform through a clean, guided onboarding flow that walks them through their case details step by step. Stripe handles all payment and subscription logic, while the portal provides a full dashboard to track every appeal ever generated, including current status, submission history, and outcome records. Nothing gets lost, and sellers always know exactly where their case stands.

How It All Fits Together

The platform runs on a serverless Next.js 14 architecture, with API routes handling all AI orchestration between the RAG pipeline and the generation engine. The two AI layers, Gemini for retrieval and GPT-4o-mini for generation, are fully decoupled, meaning each can be scaled, swapped, or improved independently without touching the other. Supabase handles all persistent data: user accounts, appeal records, prompt versions, and A/B test results. The entire system is designed to deliver a complete, submission-ready appeal document in under 3 minutes at any volume.

Retrieval-Augmented Generation sits at the core of what makes the output legally credible rather than generically plausible. Gemini doesn't just assist the prompt, it anchors every generated appeal in the language and structure of real decisions that have already worked.

The version-controlled prompt system ensures that improvements compound over time. Every prompt iteration is stored, compared against historical approval rate data, and only promoted to production when it demonstrably outperforms its predecessor. This turns the platform into a system that gets measurably better with every case it processes.
