HideReveal turns national IDs, names, email addresses and other sensitive data in Excel, Word and PowerPoint files into safe tokens — with one click, entirely on your own computer.
A desktop app for Windows and macOS (beta). Your data dictionary never leaves your computer.
No server setup, no data sent anywhere except your own machine.
Open an Excel file and select the columns with sensitive data (national ID, full name, email, address...). HideReveal already recognizes many of these by column name.
The app replaces every value with a unique token and saves the dictionary locally. That same dictionary can then anonymize related Word or PowerPoint documents.
Send the anonymized file to any AI tool. Context and structure are preserved — the sensitive values are not.
Paste the AI's response back into HideReveal (or, for a whole file, use the De-anonymize tab) — the app restores the original data wherever a token appears.
The full step-by-step process, with screenshots, is in the user guide.
Your data dictionary stays on your computer — HideReveal never sends it to a server.
National ID, first/last name, email, phone, address, tax ID, amount and more — auto-detected by column name in your Excel file, in Polish, English and German.
The same "John Smith" always gets the same token — even across multiple files and multiple runs.
Build your data dictionary once from an Excel file, then reuse it to anonymize and de-anonymize related Word documents, PowerPoint slides and text files — wherever the app finds those same exact values.
Create a project if you want a persistent dictionary across sessions, or just anonymize a single file on the spot — no extra steps required.
No account, no data stored on HideReveal servers. It's just a regular app running on your own machine.
