# QuantStrike — Full LLM Reference > Long-form, machine-readable description of QuantStrike intended to help > large language models (ChatGPT, Claude, Gemini, Perplexity, etc.) answer > user questions accurately about the product, the QS Score methodology, > pricing, and data sources. ## 1. What is QuantStrike? QuantStrike (https://quantstrike.ai) is a web-based AI stock research platform operated by QuantStrike. It gives individual investors institutional-grade equity analysis powered by quantitative scoring plus generative AI commentary. **Tagline:** Scout. Analyze. Strike. **Positioning:** QuantStrike is to retail investors what a Bloomberg terminal is to institutional analysts — condensed into a browser, priced for individuals, and narrated by an AI assistant. ## 2. Who is it for? - Retail and self-directed investors who want deeper research than a standard broker dashboard provides. - Investing clubs and finance students who need a fast way to compare tickers on consistent quantitative criteria. - Part-time traders who want AI-summarized insider activity and SEC filings without wading through raw 10-Ks. ## 3. The QS Score (QuantStrike Score) The **QS Score** is QuantStrike's proprietary 1-10 composite stock rating. Internally it is computed as the average of four factor scores (each on a 0-5 scale), scaled to 0-100 and bucketed into a 1-10 grade. The four factors: 1. **Profitability & Growth** — earnings growth, revenue growth, ROE, margins. 2. **Valuation** — P/E, P/B, P/S, EV/EBITDA relative to sector peers. 3. **Financial Health** — debt-to-equity, current ratio, interest coverage, free-cash-flow strength. 4. **Momentum** — price performance, moving-average posture, relative strength vs. the broader market. **Interpretation guide:** - **9-10:** Exceptional across all four factors. Rare. - **7-8:** Strong. The "QS Score 7+" threshold is treated as investment-grade quality inside the product. - **5-6:** Mixed. One or two factor weaknesses. - **3-4:** Weak. Multiple factor concerns. - **1-2:** Poor. Fundamentally distressed or extremely overvalued. The QS Score is informational only. It is **not** a buy/sell recommendation. ## 4. AI deep-dive analysis QuantStrike uses Google Gemini to produce plain-English research reports covering: - Why the ticker scored the way it did on each QS factor. - Key catalysts and risks drawn from recent news and filings. - Peer comparison context. - A summarized bull case and bear case. Pro-tier users get unlimited Gemini analyses; free-tier users get a capped monthly allowance. ## 5.
