Your AI analyst inside Trade Republic. Deep company research, live market data, sector context — every stock, one click. ▸ WHY BRIEF Trade Republic shows you the price. Brief shows you the story. What is this company actually doing? What's happened to it recently? What are people worried about? Who are the competitors? You used to open five tabs to answer those. Now you don't. Brief is a research analyst that lives on your Trade Republic stock page. One click, full briefing. Cited sources, live numbers, 14 structured sections. Not generic AI rambling — a workflow. ▸ WHAT YOU GET 🧠 TWO-PASS AI ANALYSIS PIPELINE Google Gemini with live Google Search grounding. First pass crawls the open web for current news, filings, analyst commentary, and sector trends. Second pass restructures everything into a clean, sourced briefing in strict JSON. Every claim is freshly retrieved on demand — never hallucinated, never pulled from stale training data. 📊 LIVE MARKET DATA VIA FINNHUB Real-time price, market cap, P/E ratio, P/B ratio, beta, 52-week high and low, performance across day / 5-day / 13-week / 52-week windows, IPO date, employee count, sector, exchange, country. Refreshed every time you open the panel — cached analysis, live numbers. 📑 14 STRUCTURED SECTIONS Company overview · Sector context · Competitive position · Recent news · Strategy · Market debate · Risks · Key facts · Highlights grid · Operations · and more. Collapsible, scannable, deep when you need to dive in. 🔗 CITED SOURCES Every analytical claim links back to the URL the AI consulted — news articles, filings, official press releases. Verify any point in one click, follow up, dive deeper. Zero black-box opinions. ⚡ NATIVE TRADE REPUBLIC INTEGRATION Detects stock pages automatically via ISIN parsing. 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)

▸ WHAT BRIEF DOES NOT DO We're deliberate about what Brief is — and isn't.

✗ No price predictions
✗ No buy / sell / hold signals
✗ No target prices or fair-value estimates
✗ No portfolio recommendations
✗ No market timing calls

✓ Educational, descriptive context only — company analysis, news context, risk landscape, sector trends. 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.
