I’ve always struggled to clearly distinguish between noise and signal in investing. So, I decided to feed my accumulated investment strategies and review notes into a large language model as a knowledge base and built a small tool — Super Digger. Key features: 1. Ready to use and free, powered by the latest and most capable AI model. 2. Stock analysis module — enables deep-dive analysis on identified targets. 3. Supports the “Position Battle” strategy, which analyzes a leading stock you input and searches within the same sector for lower-positioned stocks with the potential to become the next “catch-up leader.” (This is one of my most frequently used strategies.) 4. Supports analysis of the Polymarket prediction market.
