Hey everyone! I built chunks.md to make OCR fast, private, and hassle-free. Drop a PDF or image into your browser and get clean markdown back on desktop or mobile. Under the hood it runs 7 different OCR models via ONNX Runtime Web — from PaddleOCR v5 for general documents to manga-ocr for Japanese text. You pick the model, drop your files, and get structured text ready to paste into ChatGPT, Claude, or feed into your RAG pipeline. A few things that make it different: Fully on-device; all inference runs in a Web Worker, your files never leave your machine. Works on mobile; same full OCR experience on your phone or tablet. No account, no limits; just open the site and use it. Multiple OCR engines; PaddleOCR v5/v3, SmolDocling, PaddleOCR-VL, and manga-ocr so you can pick the best model for your content. Fully customizable; every OCR model exposes its settings (detection thresholds, crop padding, token limits, prompts, and more) so you can tune results for your specific documents. AI-native output; clean markdown chunks designed for LLM consumption. I built this for my own workflow and figured others might find it useful too. Would love to hear what you think!
