Building powerful, LLM-driven document applications often starts with an accurate and efficient parser. But for many real-world workflows, privacy is non-negotiable sensitive files must run locally on your laptop, without a single byte touching the cloud.

That local setup also has to be fast. An ideal parser should reach 5 to 10 frames per second, which means a 100-page document can be parsed in about 10 to 15 seconds, fast enough for users to move straight into interactive Q&A. But speed alone is not enough. The parser also has to handle complex layouts, dense tables, and paragraphs that span pages, scanned documents, and multiple languages.
