Cryptonyms Launches App That Lets People Choose What AI Sees in Spreadsheets

Mac and Windows app encodes names, account numbers and other private details on the user’s computer, so the AI gets the figures without the names

ASHEVILLE, NC, UNITED STATES, November 10, 2026 /EINPresswire.com/ — ASHEVILLE, N.C. – Nov. 2, 2026 – Cryptonyms today released a Mac and Windows app that swaps names, account numbers and other details a user marks private for codes, so people can ask AI about client, company or personal spreadsheets while keeping those details on their computer.

A user opens a spreadsheet in Cryptonyms and chooses which columns to protect: names, contacts, account numbers, project code names or anything else they would rather not share. One choice covers every row in that column. The app suggests what to protect, and the user reviews each suggestion and makes the call. Cryptonyms then swaps each protected value for a code such as CUSTOMER-S047 and leaves the rest of the file as it is, so the AI still gets the figures it needs to answer the question.

The user then uploads the encoded file to ChatGPT, Claude, Copilot, Gemini, Perplexity or any AI tool that accepts a file or a paste. The AI answers in codes. The user pastes that answer back into Cryptonyms, and the app turns each code into the real value again, so the user reads the answer with the real details in place before acting on it. The list that matches codes to real values stays on the user’s computer.

The same steps work on a consultant’s client pipeline, a founder’s pricing sheet or payroll, and a household budget exported from a bank. In each case the AI works with the numbers and sees codes where the protected details were.

“Most people already know the question they want to ask about a spreadsheet. What stops them is what’s in it: a client’s name, a supplier’s terms, a line from their own bank statement,” said Ray Barnes, CEO of Cryptonyms. “The person who holds the file should decide what the AI sees, detail by detail, and still get the full answer.”

People who want AI help with a sensitive spreadsheet have faced three choices: strip private details out by hand, ask a vaguer question and get a generic answer, or skip AI and do the work themselves. Cryptonyms adds a fourth: keep the file intact and code only what is private.

The app also works on pasted text, such as call notes or transcripts. The app flags names and terms for the user to review, and one decision covers every mention.

Cryptonyms acts as a technical control, not a compliance program. Teams can use it as the review step before a file reaches an AI tool. Client agreements, company policies and the rules of each profession still decide what a user may share.

Cryptonyms runs on macOS 11 or later, on Apple silicon and Intel, and on Windows 10 or later. A seven-day free trial is available at getcryptonyms.com. An individual license costs $12 a month or $120 a year, with a refund available within 30 days of any payment. Teams of five or more can buy licenses at team rates.

A 60-second video shows the app protecting a spreadsheet, sending it to an AI tool and decoding the answer. Logos, screenshots and video files are in the Cryptonyms press kit.
