TrendBreaker AI - Viral Video Script Generator

TrendBreaker AI is a self-hosted AI script studio for affiliate creators, social sellers and small brands who sell with short product videos.

Upload a product photo, paste a screenshot, or paste a product page link. Google Gemini Vision reads the packaging and fills six editable product fields. TrendBreaker then writes three different ready-to-film scripts, each with a 3-second hook, a retention body, a call to action and a timestamped shot guide a creator can shoot with just a phone. A built-in full-screen teleprompter lets them record it in one take.

NO DATABASE REQUIRED TO START Visitors use every feature as guests, with zero sign-up. Scripts are saved in the browser. When you want accounts, connect a free Supabase project to add email + password and "Sign In with Google", with Saved Scripts synced across devices.

WHY BUYERS CHOOSE IT - A clear niche: creators producing 30-50 short product videos a day need speed, not a blank page. - Real workflow, not a chat box: product intake, vision scan, script formulas, shot guide, teleprompter and script library in one screen. - Built to rebrand: white-label it for your agency or creators, or use it as the starting point for your own AI SaaS. - Clean modern stack: Next.js 16, React 19, TypeScript, Tailwind CSS v4, Vercel AI SDK, Zod and optional Supabase. - Bring your own AI: Google Gemini (free tier works), with optional OpenAI and Groq fallbacks that switch in automatically.

LIVE DEMO https://trendbreaker-ai.vercel... No sign-up needed. Open the "Specific Products" tab and drop any product photo.

WHAT YOU GET - Complete, un-minified Next.js source code (TypeScript) - Supabase SQL schema: tables, automatic profile trigger and owner-only row-level security - Reference JSON copies of all prompt presets and policy rules - Offline HTML documentation and a printable PDF user manual, including step-by-step Supabase and Google OAuth setup

TRANSPARENCY & COMPLIANCE - No credits, tokens, points, payments or gambling mechanics of any kind. - No licence keys, domain locks, activation servers or phone-home checks. The code is fully readable. - Analytics are off by default. Optional Vercel Analytics reports only to the buyer's own Vercel account. - You bring your own API keys. Product images go only to the AI providers you configure. - TrendBreaker AI is an independent tool. It is not affiliated with or endorsed by TikTok, Shopee, Lazada, Amazon, Google or OpenAI. Platform names only describe compatibility. The policy filter lowers risk but cannot guarantee platform approval, so creators should review scripts before publishing.
