Detection options
2Mask files
Excel becomes a masked workbook plus a Markdown rendering; PDFs become masked text (black-box redaction is available in the file studio). Everything joins the same session vault.
3Unmask Claude's reply
Paste the answer back. Tokens are restored from this session's vault, even when the model changed their case, split them with spaces or shortened the id. Anything it cannot resolve is listed, never guessed.
4Unmask a file Claude made
Drop a spreadsheet, Word or PowerPoint file, Markdown, CSV or text that Claude produced. Tokens inside are restored from this session's vault; anything unresolved is listed and, for workbooks and Markdown, noted inside the file. PDFs are not supported.
