It really isn't an exaggeration! LiteParse clocks in at an average of 3ms per page for a reason: it skips the heavy AI processing and cloud overhead entirely. Here is exactly how it pulls off that kind of speed: - Purely Local & Lightweight: It runs completely on your machine (built on a Rust core with a native PDFium C library) rather than sending files over the network to a distant cloud server. - No Heavy VLMs/GPUs: Instead of using an expensive, slow Vision-Language Model to "read" the page layout, it relies on fast, deterministic layout heuristics and projects text onto a spatial grid. - Selective OCR: It only activates OCR (using lightweight engines like Tesseract) when it encounters scanned pages or embedded images; otherwise, it extracts native text layers directly. Because it reconstructs headings, tables, and lists into structured Markdown almost instantly, it's a massive win for real-time RAG pipelines and coding agents that need a quick first pass over documents. Quick demo 🧵👇 LiteParse is unreasonably good for document parsing ✅ It is the fastest document parsing tool out there - average parse time per page is 3ms ⚡️⚡️ ✅ Now that we support markdown, it tops opendataloader-bench, OlmOCR-bench, and ParseBench in terms of accuracy ✅ It supports 50+ othe…
