Best OCR Solution for LLM Inputs with Space-Aware Layout & citation generation.

This tool performs exceptionally well and is tailored specifically for LLM inputs. Before settling on this one, I experimented with several other OCR solutions, but this proved to be the most effective. The space-aware layout feature is particularly useful. For the most part, it simply works—the document outputs generally match expectations. Errors such as mismatched lines or incorrectly parsed text are rare. Also, the fact that it returns bounding boxes for each line makes it very easy to show citations for ai-generated results, which is helpful for verification.

Perfect Precision in Document Layout and Data Extraction

What I really like it how it preserves the original document layout and the precision I've been getting when trying out. I've been testing it out for personal use with receipts as images and pdfs with payments details to extract data as table with the use of an llm and it has worked with perfect precision. I still have to try the API, but I also like it comes with a postman documentation for testing. The API also seems easy to use, at least from the examples I have read. I also realized it has a n8n and MCP integration which will be very usefull for my uses.
