Dexter Pros
- Self-validation catches errors that single-pass AI tools miss — the agent re-researches until findings are consistent
- Full transparency via scratchpad logs: every tool call, every data point, every decision is traceable

- Supports fully local execution via Ollama — your financial queries never leave your machine
- Clean TypeScript codebase with modular agent architecture — easy to extend or fork
Dexter Cons
- CLI-only interface with no web dashboard or visualization — you get text output, not charts
- Requires Financial Datasets API key plus an LLM provider API key — setup takes 10-15 minutes
- Analysis quality drops significantly with cheaper/smaller LLMs — OpenAI GPT-4 class models recommended for complex queries
- No portfolio tracking, alerts, or ongoing monitoring — it's a research tool, not a trading platform
- Rate-limited by Financial Datasets API — heavy users may need a paid tier for real-time data access
