Choose curator if…
- curator is primarily Python; unstructured is HTML.
- Tags unique to curator: agents, fine-tuning, instruction-tuning, llm.
- Ideal for enhancing the performance of existing machine learning models through fine-tuning in natural language processing contexts
When NOT to use curator
- Not recommended if your needs extend beyond NLP and you do not work with structured text data
- May not be the best choice for simple data generation tasks that do not benefit from complex synthetic dataset creation processes
Choose unstructured if…
- unstructured is primarily HTML; curator is Python.
- Tags unique to unstructured: data-pipelines, document-image-analysis, document-image-processing, document-parser.
- Also covers Data & Retrieval.
- unstructured ships Docker support for self-hosted deployment.
- When you need to convert a variety of document types, including PDFs and images, into structured data formats suitable for language models.
When NOT to use unstructured
- If you are working with simple text files that do not require complex parsing or enrichment processes.
- When you need a tool that supports real-time document processing, as Unstructured is optimized for batch processing and may not be suitable for real-time applications.
- If you are looking for a solution that does not require setting up a Docker environment or managing dependencies with uv.
- When you need a tool that supports a wider range of document types beyond PDFs and images, as Unstructured may not cover all your document format needs.
