Anonymize a CV or resume before an AI screens or rewrites it
Paste a CV, or drop it as a Word file. The candidate's name, address, phone, email, profile link and date of birth become codes, and so do employer names unless you keep them readable; job titles, skills and achievements stay as they are. Use it to screen candidates with an AI, or to have your own CV rewritten without giving it your identity.
Restoring uses the key of this tab: code your text here first, keep this tab open, then come back with the answer.

connect-src 'none' in its security policy) and loads no analytics. Turn Wi-Fi off once the page has loaded: the tool works just the same. The engine is the one inside the Hidden Tokens app.How it works
1 · Code
Paste a text or drop a file. Names, companies, addresses, emails, phone numbers, bank details, ID and case numbers become codes such as NAME-001 or COMPANY-001. Unknown proper nouns are coded too: when in doubt, the engine codes.
2 · Send the codes
Copy the coded text, or download the coded file, and give it to ChatGPT, Claude, Gemini or Copilot. The AI reasons on the codes: it still knows who did what, not who they are.
3 · Restore
Paste the AI's answer in the Restore tab, in the same browser tab. The codes become the real names again, on your screen only.

The town stays readable too: check whether, with the rest, it points to one person.
Screening with AI, without the bias and without the identity
Recruiters paste CVs into AI tools every day. Each CV is a full set of personal data, sent for someone who never applied to that AI. Coding the identity also removes what should not weigh on the shortlist: a name, an age, an address.
- Coded: name, address, phone, email, profile links, date of birth, and employers and schools that the engine treats as proper nouns.
- Your choice: employers can matter for the assessment. Keep a well-known employer readable under Adjust → Keep readable, or leave it coded if the role, not the brand, is what counts.
- Readable: job titles, skills, tools, achievements and figures such as “12 clients”.
Comparing several candidates? The free tool codes one CV at a time with a new key, so NAME-001 is a different person in each run: restore each answer before coding the next CV. The Hidden Tokens app keeps one key for a whole recruitment folder.

A word on the word “anonymize”
Strictly speaking, this tool pseudonymizes: each value is replaced by a code that can be reversed with the key. Under the GDPR, pseudonymised data is still personal data for whoever holds the key, which here is you, in this tab. What the AI receives no longer names anyone directly. Clues can remain, such as a job, a town and an age together: the tool warns you when it sees them. Read the result before sending it.
Questions
Can I paste several CVs at once?
Yes, up to 3,000 words in total, and each candidate gets their own code in that run. Restore the answer before coding another batch, since each coding starts a new key.
Does it remove photos from a Word CV?
Yes. The coded Word copy removes images, embedded objects and the author in the file properties.
Should employers be coded?
It depends on your question. For blind screening, leave them coded. If the employer matters, keep it readable under Adjust; the candidate stays coded.
Can I use it to have my own CV rewritten?
Yes. Code your CV, ask the AI to improve it on the codes, then restore the new version here: the AI never had your name or contact details.
