LexifAI - Custom AI OCR Chatbot
About this Project
Developed LexifAI, a custom AI-powered document analysis engine featuring advanced OCR technology and intelligent text processing. This comprehensive system combines computer vision, natural language processing, and machine learning to extract, analyze, and provide insights from various document types with high accuracy and speed.
Reads almost anything
PDFs, photos, and screenshots go in, clean text comes out, with better than 95% accuracy on real documents.
Ask instead of searching
Instead of scrolling through a document, you ask a question and the chatbot answers from the extracted text.
Built from scratch
The OCR engine and language pipeline are custom built, not a wrapper around an off-the-shelf service.
Made for mobile
The whole engine is optimized to run inside a mobile app, processing documents in real time on the go.
Document photos are messy, with shadows, angles, and low light. Getting accuracy above 95% took heavy preprocessing work, from perspective correction to adaptive thresholding, before the text even reaches the recognition model.
LexifAI became the document brain of NOTEorious and a standalone showcase of applied machine learning, from raw pixels to a useful answer.
