I will build a custom ai document checker with python and ocr
About this gig
Do you have hundreds of PDFs, invoices, or passports that you need to read and organize?
I build custom AI Document Checkers using Python, OCR, and LangGraph. I don't just extract text; I build systems that understand the data, check it against your rules, and give you a clear result.
WHAT YOU WILL GET:
High-accuracy OCR (Tesseract) to read scanned PDFs and images
AI extraction (using GPT or Gemini) to pull out specific fields (names, dates, amounts)
A rules engine to validate the data (e.g., checking if a date is valid or a balance is correct)
Clean output in CSV, Excel, or a Streamlit dashboard
I recently built a UK Visa Auditor that reads passports, CAS letters, and bank statements, checks the 28-day funds rule, and gives a score. You can see my code and video demos here: https://github.com/taimoorcodes-cmd
Message me with a sample of your document, and I will tell you exactly how I can automate it.

FAQ
What types of documents can you process?
I can process PDFs, JPGs, and PNGs. This includes invoices, passports, bank statements, contracts, and reports.
Do I need to provide an API key?
Yes, you will need an OpenRouter or OpenAI API key for the AI extraction part. I will guide you on how to set it up.
How accurate is the OCR?
For clear, printed documents, the accuracy is very high (90%+). For blurry or handwritten documents, I add an AI fallback to ensure the best possible extraction.
