    """# Document redaction

    Redact personally identifiable information (PII) from documents (pdf, images), open text, or tabular data (xlsx/csv/parquet). Please see the [User Guide](https://github.com/seanpedrick-case/doc_redaction/blob/main/README.md) for a walkthrough on how to use the app. Below is a very brief overview.
    
    To identify text in documents, the 'local' text/OCR image analysis uses spacy/tesseract, and works ok for documents with typed text. If available, choose 'AWS Textract service' to redact more complex elements e.g. signatures or handwriting. Then, choose a method for PII identification. 'Local' is quick and gives good results if you are primarily looking for a custom list of terms to redact (see Redaction settings). If available, AWS Comprehend gives better results at a small cost.
    
    After redaction, review suggested redactions on the 'Review redactions' tab. The original pdf can be uploaded here alongside a '...redaction_file.csv' to continue a previous redaction/review task. See the 'Redaction settings' tab to choose which pages to redact, the type of information to redact (e.g. people, places), or custom terms to always include/ exclude from redaction.

    NOTE: The app is not 100% accurate, and it will miss some personal information. It is essential that all outputs are reviewed **by a human** before using the final outputs.""")
