## Shared compatibility

- **Python**: [fact-checker](/tools/jagilley-fact-checker.md) - Python runtime; [AutoRAG](/tools/marker-inc-korea-autorag.md) - Python runtime

## Choose when

### Choose fact-checker if…

- fact-checker is primarily Jupyter Notebook; AutoRAG is Python.
- Tags unique to fact-checker: python, jupyter notebook.
- Leaner open-issue backlog (0).

### Choose AutoRAG if…

- AutoRAG is primarily Python; fact-checker is Jupyter Notebook.
- Tags unique to AutoRAG: automl, evaluation, embeddings, document-parser.
- Also covers Data & Retrieval.

## When NOT to use fact-checker

- Last GitHub push was 992 days ago (dormant maintenance, Oct 23, 2023). Validate activity before betting a new project on fact-checker.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use AutoRAG

- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.
