Overview
What Dexter is
Dexter runs as a terminal-based research agent rather than a hosted stock-picking service. It selects finance and search tools, records its work in a scratchpad, and can produce analyses such as company comparisons, earnings research, and investment memos.
The project explicitly limits itself to educational and informational use. Its output can be incomplete or wrong, and the live data sources, model providers, and search services require separate credentials, licenses, and verification before any financial decision.
Use cases
Who Dexter is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.

Assessment
Dexter strengths and limitations
Where it stands out
- Makes the research plan and tool trail inspectable rather than hiding them behind a black-box recommendation.
- Supports multiple model providers and finance-specific data tools.
What to consider
- It is a technical self-hosted project that requires credentials and maintenance.
- Outputs are not financial advice and must be checked against primary filings and timestamped market data.
