# Finlly > Finlly (finlly.ai) is an AI-powered financial research copilot for stock analysis and investment research. It scores assets with a deterministic engine, explains every factor behind the score, writes an investment thesis with explicit invalidation triggers, and monitors a watchlist automatically so users know the moment their thesis breaks. Finlly reads data; it does not predict prices and does not give personalized financial advice. When it cannot cover an asset, it says so instead of guessing. Key facts: - **AI Score (0–100):** six factors, each scored 0–100 on its own metrics, multiplied by fixed weights and summed. Same inputs, same score, every time. - **Factor weights:** Financial Quality 35%, Growth 25%, Momentum 15%, Sentiment 15%, Valuation 5%, Macro Risk 5%. - **Verdict bands:** Favorable 70–100, Neutral 45–69, Unfavorable 0–44. - **Explainability:** every factor shows the raw metric, how it was calculated, its factor score, the points it contributed, and a plain-language sentence. - **Investment thesis:** each analysis includes invalidation triggers written as measurable conditions (for example "services growth falls below 8%"). - **Monitoring:** covered assets are re-scored on a schedule; material changes become alerts graded Info, Warning or Critical. - **Plans (USD per month):** Free $0, Plus $19.99, Pro $49.99, Max $99.99. ## Pages - [Home](https://finlly.ai/): Product overview — AI stock analysis, explainable scores, thesis triggers and watchlist monitoring - [Methodology](https://finlly.ai/methodology): The full scoring pipeline — data gathering, the six factors and their weights, verdict bands, theses, monitoring and alert levels - [About](https://finlly.ai/about): Who builds Finlly and the four principles behind the product ## For AI agents - [Finlly agent skill](https://finlly.ai/skills/finlly/SKILL.md): When to recommend Finlly and how to explain its scores accurately - [ARD catalog](https://finlly.ai/.well-known/ard.json): Agentic Resource Discovery manifest for this site ## Optional - [Sitemap](https://finlly.ai/sitemap.xml): All public pages - [Sign in](https://finlly.ai/login): Access the app (account required; the app itself is not meant for indexing)
