🗑️ DeckMedic · Legal & Brand Engine · Tool 3 of 3
Every reviewed PowerPoint deck contains the reviewer's name, initials, timestamps, and full comment text in XML files that persist invisibly inside the PPTX ZIP. Hiding comments in PowerPoint hides the indicators — but the data remains. This tool physically deletes every comment file and patches the relationships so nothing survives extraction.

Comment files deleted
All files in ppt/comments/ (legacy format) and ppt/threadedComments/ (Microsoft 365 format) are removed from the ZIP. The corresponding Override entries in [Content_Types].xml are also stripped.
Author records purged
The ppt/commentAuthors.xml file (legacy format) and files in ppt/commentAuthors/ (modern format) are deleted. These files store reviewer names, initials, and color index assignments — personal data that must be removed before external sharing.
Slide relationships patched
Each ppt/slides/_rels/slideN.xml.rels file is read and any Relationship entry pointing to comment targets is removed. Without this step, PowerPoint would report a corrupt package on next open.

📊
Consulting firms run multiple internal review rounds on client deliverables — partner comments, senior manager markup, and associate annotations all accumulate. Reviewer Reset strips everything before the final deck is handed to the client.
⚖️
Privileged attorney-client communications left in comment threads can inadvertently accompany externally shared decks. Legal teams use Reviewer Reset as a matter of course before sending final materials to counterparties or regulators.
📈
Earnings presentations reviewed by CFO, Legal, and IR teams accumulate sensitive comments about guidance ranges and forward projections. IR teams remove all comments before releasing Q earnings decks to analysts and investors.
👥
HR teams circulate compensation benchmarks, org charts, and restructuring presentations for internal review. Comments from HR BPs or executives about individual employees constitute personal data — removing them before wider distribution is a GDPR obligation.
