Send three slides, not the deck

Selective share lets you send only the pages or slides someone should see. Paired with AI-proof .nkxd files, the rest of your document never leaves your hands.

An investor asks for your traction numbers. You send the whole deck, because that is how decks work.

Now they have your cap table. Your burn. Your hiring plan. Your list of competitors and what you think of each one.

And because it is 2026, the first thing their associate does is upload the deck to AI and ask for a one page summary. Your entire company, condensed, sitting in someone's chat history.

You wanted to share three slides.

Sharing has always been all or nothing

Every tool you use treats a file as one thing. You send it or you do not.

If you want someone to see part of it, you make a copy. Delete the pages. Hide the sheets. Save as a new file. Send that. Then do it again for the next person, and try to remember which version went where.

Most people skip this. They send the whole file and hope.

Selective share

NakodaX lets you pick what goes out. Pages of a PDF. Slides of a PowerPoint. Sheets of an Excel workbook. Sections of a Word document.

You keep one master file. Each recipient gets their slice. The investor sees traction. The client sees pricing but not cost. The publisher sees three chapters, not the book. The vendor sees their section of the agreement, not the other vendors' rates.

Nobody gets a copy of the rest. There is no rest on their side. It never left.

And what does go out stays out of AI

The slice you share arrives as a .nkxd file. It opens in a browser through NakodaX, with the access you set.

Drop it into ChatGPT, Copilot, or any AI tool and it returns nothing. The content is encrypted inside the container. There is no text for an AI to read.

So the investor sees three slides, on screen, with their name watermarked on each one. They cannot paste the slides into an AI. They cannot forward them to someone who can. And when the round closes or the conversation dies, you revoke, and the three slides stop opening too.

Unless you decide otherwise. If you want a recipient to be able to export and analyze what you sent, you can allow it. The point is that it is your call, not theirs.

Where this changes the story

The proof moment: share only the address page of your passport, only the salary rows of a bank statement, only the income line of a tax return. The person asking gets what they need to verify you, not a document they can run through AI to learn everything else about you.

The deal moment: one master proposal, a different slice per prospect. Each one sees their pricing, their scope, their terms. None of them can feed your proposal into AI to reverse engineer how you price everyone else.

The relationship end: partition one contract across every party. When the contract ends, revoke. There was never a full copy on their side to begin with, and there was never a readable one.

The takeaway

Send three slides, not the deck. Share the part they should see, keep the rest with you, and keep AI out of all of it unless you allow it.
