Details: Small businesses and freelancers struggle to have convincing marketing. We built a marketing tool to empower small businesses and freelancers that don’t have the money and time to go the conventional route with marketing. Marketeer generate the banners, video advertisements, jingles, and voice overs tailored to each client.

Models and Gemini API features: Marketeer leverages multiple Gemini API models. Nano Banana 2 for logo and banner generation, Lyria for AI jingle creation, Veo for video production, and Gemini 3.1 Flash for all text generation and campaign strategy.

Issues: Our biggest challenge was combining video and audio using FFmpeg WASM in the browser, which required over an hour of debugging codec, CORS, and SharedArrayBuffer issues. We resolved it by properly configuring cross-origin isolation and media encoding formats to keep all processing client-side.
