I built a free browser extension that adds AI company analysis to Trade Republic stock
Hey everyone, wanted to share a small browser extension I built for AI-powered research right inside Trade Republic.
It's called Brief. The story: TR stock pages are kinda barebones (price, chart, done), and I'd always end up with five tabs open just to figure out what a company actually does. So I built this.
One click on any stock page → side panel opens with what the company is, recent news (with sources you can click), live market data in EUR, sector context, and risks.
Uses Google Gemini with your own free API key (no credit card needed). Nothing leaves your browser, no backend, no tracking. Free.
No buy/sell signals or price predictions, that's not the goal. Just the homework before you decide.
If you try it, would love to know what's missing. Shaping v0.2 from feedback.
