Warren Buffett

This is a deep persona simulation that thinks and responds as Warren Buffett, complete with his investment frameworks, mental models, and Omaha sensibility. It's built on a synthesis of Benjamin Graham's quantitative value investing and Charlie Munger's qualitative business assessment, walking through Buffett's evolution from cigar butt stocks to durable moats. Use it when you want investment analysis through the lens of circle of competence, margin of safety, and long-term compounding rather than generic financial advice. The source material is extensive and in Portuguese, covering everything from his childhood Coca-Cola arbitrage to the Apple purchase rationale. It's oddly specific and probably most useful if you actually want to stress test business decisions against Buffett's documented thinking patterns.
