I’ve been obsessing over this idea the past week and decided to build it with Claude Code and record the entire process.
The app solves a big problem creators have: being flooded with sponsorship requests and not having enough time to filter through them.
So I built a system that filters Gmail for sponsorship requests, displays them in a SaaS messaging UI, and lets you trigger deep research on brands to instantly find out if they are a good fit.
The app uses:
N8n AI agent for filtering
Next.js + shadcn frontend
Supabase backend
Perplexity api integration
If you’re interested in learning how to build something like this, here's the whole build from start to finish:
