I've also tried tesseract in the past with handwritten notes, which didn't provide very accurate results. Then I started looking into some commercial solutions and stumbled upon many different tools, but the only one that could handle my handwriting was Klippa DocHorizon: https://www.klippa.com/en/ocr/ It uses machine learning and OCR instead of just plain OCR like tesseract does, so it might be an option to look into. You could also test it out at https://www.klippa.com/en/ocr/tools/
I've been using it for a while and would highly recommend it. hopefully it can work out for your use case
