Kasiel vs ChatGPT for stocks
Using a general-purpose LLM for investment research — free, but limited
TL;DR
Lots of investors use ChatGPT for stock research — ask it to summarize earnings, build a model, suggest a portfolio. It's free at the basic tier and the writing quality is excellent. The two big problems: (1) without a live data plugin, ChatGPT can hallucinate or use stale information; (2) it's a general-purpose tool, not built for investing — no real-time fundamentals, no source attribution, no track record. Kasiel is purpose-built for stock analysis with live data and a public auditable record.

Bottom line
ChatGPT is great for understanding investing concepts and summarizing what you give it. It's risky as a primary stock research tool because of hallucination risk and the absence of any track record. Use ChatGPT for the 'what does this mean' questions; use Kasiel when you actually need to decide whether to buy a specific ticker.
