Hours on this deck. Handing it to an AI to rewrite, translate or rework saves a huge amount of time, and the temptation is real. But a sales or consulting presentation is never a neutral document: it names clients, shows figures no competitor should ever see, and trails behind every slide notes that nobody in the room ever reads. One copy-paste. All of it gone.
A sales deck, before and after
The client, amount and contact are masked. The AI rewrites or structures the deck without knowing who it is for.
The trap: speaker notes and metadata (author, company) travel with the file, even if they do not show. Remember to clean them too.
Speaker notes, the leak you cannot see
This is the blind spot by excellence. Below each slide, the notes pane often holds what you would never put on screen: the real margin, the name of the decision-maker to win over, the line "do not show the client" scribbled one late deadline night. You export. You paste into the AI. And those notes travel with it, intact, even though they never appear in presentation mode. The habit that saves you: open the notes pane and read it slide by slide, because that is exactly where the most compromising sentences hide.
Client logos, confidential figures and file metadata
A client logo in the footer. It identifies the account as surely as a name spelled out in full. Target revenue, market shares and price ranges spell out your entire strategy to anyone who can read between the lines. And the file itself forgets nothing: author, company name, save path, sometimes the full version history, all tucked away in the metadata. Spotless on screen. Talkative in its properties.
What to mask, what to keep
You pseudonymize. Client and contact names, amounts, market shares, internal project names and speaker notes all move behind a pseudonym. You keep the rest: the reasoning, the structure, the analysis, which is exactly the material the AI needs to work on. And all of it stays reversible. Once you get the AI's answer back, you drop the real names into your final version without retyping a single line.
Safe-Doc handles both. It pseudonymizes the content of the slides as well as the notes, strips the metadata along the way and preserves the original layout. See the ChatGPT and GDPR at work guide.
Not just the visible slides. Pseudonymize the entire deck, then clean notes and metadata before you send it to the AI.
