Adapts to Trade Republic's single-page navigation — no full reload needed. Shadow DOM isolation means Brief never breaks Trade Republic's own design, and Trade Republic's CSS never bleeds into Brief. 🔒 PRIVACY-FIRST ARCHITECTURE No backend. No tracking. No telemetry. No analytics. Brief talks directly from your browser to three endpoints: • Gemini — using your own free API key • Finnhub — open free tier, no signup • Frankfurter — ECB-sourced FX, no auth Your Gemini API key is stored only on your device, never synced, never sent anywhere except to Google's official Gemini endpoint. Nothing about you, your stocks, or your analysis touches our servers — because we don't have servers. 🚀 SMART CACHING Each analysis is cached locally for 7 days — open the same stock twice, get instant results. Prices and market data refresh on every open (live numbers always). Regenerate on demand if you want a fresh take. Cache is automatically invalidated when we ship prompt improvements, so you never see stale logic. ▸ GETTING STARTED (60 SECONDS) 1. Install Brief 2.

The homework a serious investor wants to read before deciding anything. This is by design. EU MiFID II regulations take a strict view of unlicensed investment advice, and we agree with the spirit of those rules. Brief is your research analyst — not your broker. ▸ WHO IT'S FOR • DIY investors doing their homework before clicking Buy • Trade Republic users tired of bare-bones stock pages • Anyone who'd rather read one solid briefing than 12 browser tabs • Investors who want to understand WHY a stock is moving, not just THAT it is ▸ PRICING Brief itself is free. Google's Gemini free tier is generous — typically enough for hundreds of stock analyses per month at zero cost. Bring your own key, keep full control. Brief is an independent third-party extension. We are not affiliated with, endorsed by, or sponsored by Trade Republic Bank GmbH. "Trade Republic" is a trademark of its respective owner and is used here for descriptive compatibility only.
