Choose pdfmux if…
- Tags unique to pdfmux: ocr, pdf-extraction, self-healing, structured-extraction.
- pdfmux ships Docker support for self-hosted deployment.
- You need high accuracy without LLMs or GPUs.
When NOT to use pdfmux
- Require real-time GPU-based AI processing for speed.
- Working with non-PDF file formats as sole tool.
Choose chunktuner if…
- Pricing: Open source with an MIT license, offering free use for both personal and commercial projects. No costs beyond typical computing resources are implied by its usage..
- Tags unique to chunktuner: chunking, embedding, evaluation, langchain.
- - You are working specifically with retrieval-augmented generation (RAG) systems which require tailored optimization and evaluation.
When NOT to use chunktuner
- - If you do not deal with RAG systems or if the nature of your workflow does not benefit from specific optimizations in text chunking strategies across a corpus.
- - You are working on projects that don't necessitate evaluation and optimization at the level provided by 'chunktuner', such as simpler tasks that can be managed without extensive configuration tools.
