If you want to build a Local OCR application so that you do not need to send your documents to APIs. You can use 𝐒𝐦𝐨𝐥𝐃𝐨𝐜𝐥𝐢𝐧𝐠, which is an ultra-compact vision-language model for end-to-end multi-modal document conversion that can be used for LocalOCR.

𝗦𝗺𝗼𝗹𝗗𝗼𝗰𝗹𝗶𝗻𝗴 is a compact 256M open-source vision language model designed for OCR. It offers end-to-end document conversion without complex pipelines, allowing a single small model to handle everything.

It’s fast and efficient, processing a page in just 0.35 seconds on a consumer GPU with less than 500MB VRAM. Despite its small size, it delivers high accuracy, outperforming models 27× larger in full-page transcription, layout detection, and code recognition.

In this two-part hands-on tutorial, we’ll build a local OCR application using 𝗦𝗺𝗼𝗹𝗗𝗼𝗰𝗹𝗶𝗻𝗴. In the second part, we’ll develop the OCR web application, and we’ll integrate everything from the first part and create the application interface using streamlit.
