Hintyr permanently removes sensitive content from files using redaction designed for litigation. Choose from text selection, box drawing, full-page redaction, keyword search, batch processing across files, and AI-assisted detection of personally identifiable information.
What document redaction does
Document redaction permanently removes sensitive, privileged, or irrelevant content from files before you produce or share them. Under FRCP Rule 5.2, court filings must redact Social Security numbers, taxpayer IDs, birth dates, minor names, and financial account numbers. Covering text with a black box in a word processor isn't enough. Proper PDF redactioneliminates the underlying content from the file so it can't be copied, searched, or recovered.
In Hintyr, redaction is built into the document review workflow. Redact files from within the document viewer without leaving your case or switching to external tools. Hintyr also scrubs document metadata during redaction, sohidden data like author names, revision history, and embedded comments are removed as well.
Document redaction methods
Hintyr offers several redaction methods, each suited to different situations. Combine multiple methods on the same document as needed:
- Text selection - Click and drag to select specific text for redaction. Best for targeted removal of names, numbers, or phrases.
- Box drawing - Draw rectangles over any area of the page to redact images, signatures, handwritten notes, or any non-selectable content.
- Full-page redaction - Mark entire pages for redaction when they're entirely privileged or irrelevant.
- Keyword search - Search for specific terms within a document and redact all or selected occurrences at once.
- Batch redaction - Search for keywords across multiple files in your case and apply redactions in bulk.
- AI-assisted redaction - Tell the AI agent to find and flag sensitive information like Social Security numbers, phone numbers, or email addresses across your case files.
How PDF redaction works in Hintyr
Hintyr's redaction workflow follows a two-step process that prevents accidental removal. First, mark areas for redaction using any method above. These markings appear as pending annotations you can review, adjust, or remove before they take effect. Second, apply the pending redactions to permanently remove the marked content from the file.
Separating marking from applying gives you full control. Review all pending redactions in the annotation sidebar before committing. Remove any marking before it's applied without affecting the original document. Once applied, redactions are permanent, but you can always revert to the original file if needed.
