# OpenEcon.ai

> Free, open-source AI tools for economics research, built by Lu Han. Search 330,000+ economic indicators in plain English, run Stata and MATLAB from AI assistants, and draft, present, and referee papers with AI.

## Find and access economic data

- [Economic Data Search](https://data.openecon.ai/): Search 330,000+ economic indicators by asking in plain English. Covers FRED, World Bank, IMF, Eurostat, and 10+ sources.
- [openecon-data (MCP server)](https://github.com/hanlulong/openecon-data): Give your AI assistant direct access to economic data from FRED, World Bank, IMF, and 10+ sources.
- [awesome-ai-for-economists](https://github.com/hanlulong/awesome-ai-for-economists): A curated directory of the best AI tools, libraries, and resources for economics research.

## Analyze and compute

- [stata-mcp](https://github.com/hanlulong/stata-mcp): Let Claude run Stata commands, execute .do files, and explain econometric output.
- [matlab-plot-skill](https://github.com/hanlulong/matlab-plot-skill): Publication-quality MATLAB figures — clean subplot layouts and vector PDF export for LaTeX and Overleaf.
- [overleaf-sync-now](https://github.com/hanlulong/overleaf-sync-now): Stop AI assistants from silently overwriting your Overleaf edits — web changes are pulled before every read and write.

## Write, present, and get feedback

- [econ-writing-skill](https://github.com/hanlulong/econ-writing-skill): Structure, draft, and revise economics papers with AI — section formulas, field conventions, and lessons from 50+ writing guides.
- [econ-slides-skill](https://github.com/hanlulong/econ-slides-skill): Turn your paper into a professional Beamer talk — speaker scripts, discussant decks, and every number traced to its source.
- [econ-paper-review-skill](https://github.com/hanlulong/econ-paper-review-skill): Get a tough, fair referee report before a real referee sees it — identification, tables, proofs, and references all checked.

## Data platform

- [data.openecon.ai](https://data.openecon.ai/): Natural-language search over 330,000+ indicators from FRED, World Bank, IMF, Eurostat, Statistics Canada, BIS, UN Comtrade, OECD and more.
- [MCP endpoint](https://data.openecon.ai/mcp): Connect the data platform to your AI assistant. Install: `claude mcp add --transport sse openecon-data https://data.openecon.ai/mcp --scope user`

## The road ahead

- [econ-auto-research](https://github.com/hanlulong/econ-auto-research): An economist-directed AI system that goes from research question to working paper — with identification judgment, adversarial self-refereeing, and number provenance.
