How do I remove personal information before pasting a conversation into ChatGPT?

Download Mirror Veil and open it. Choose your export, leave redaction on, and download the cleaned file. Names, phone numbers, emails, street addresses, and card numbers are replaced with tokens before the text ever leaves your device, so nothing sensitive is in what you paste.

Does Mirror Veil upload my conversation anywhere?

No. Mirror Veil is a single HTML file you download and open on your own device. It has no server to upload to. You can disconnect from the internet entirely and it still works.

Does it keep the same person consistent throughout?

Yes. Mirror Veil links a nickname, handle, phone number, and email belonging to one person to a single token, so Mike, Mikey, and his number do not become three unrelated blanks. When an identifier could belong to two people it falls back to a generic token rather than guessing.

What is the redaction receipt?

A text file recording what the tool removed: a count for each category, how many people it resolved, and a SHA-256 hash of both the input and the output. It proves what was taken out without revealing any of the content.

Is a redacted conversation truly anonymous?

No, and Mirror Veil does not claim that. Identifiers are removed, but context can still identify people. Read the cleaned file before sharing it.

Yes. Mirror Veil is free, requires no account, and there is nothing to sign up for.

Mirror Veil: Redact a Conversation Before You Share It

Free tool that removes names, numbers, emails and addresses from a chat export on your own device. No upload, no account, no server.

How do you redact a conversation before sharing it?

Mirror Veil strips names, phone numbers, email addresses and other identifying details out of a chat or message export before you hand it to a lawyer, a therapist, or an AI. It is a single HTML file you download and open, so there is no upload, no account and no server; disconnect from the internet and it still works, which is a faster way to verify that than reading a privacy policy. It is free and MIT licensed.

One person stays one person: it builds an alias graph, so "Mike", "Mikey" and his phone number all become the same stable token instead of three unrelated blanks.
That matters because pattern-based redactors destroy the thread — whoever reads the result can no longer follow who said what, which defeats the point of sharing it.
Nothing is uploaded. The file runs entirely in your browser, and it keeps working with the network disconnected.
Handles exports from iMessage, WhatsApp, Instagram DMs and Android SMS, plus plain CSV, JSON, TXT and HTML transcripts.
Open source under MIT at github.com/justlayme/mirror-veil, so the redaction logic can be reviewed rather than trusted.
Useful before sending a conversation to a therapist or solicitor, before pasting one into ChatGPT or Claude, and before uploading anything to Grey Mirror itself.

Mirror Veil is a free tool that removes the identities from a conversation before it is shared with a lawyer, a therapist, or an AI assistant. It is a single HTML file that runs entirely on the user device: there is no upload, no account, and no server, so the conversation never leaves the machine it is opened on.

It removes names, nicknames, handles, phone numbers, email addresses, street addresses, and card numbers, while deliberately preserving timestamps, turn taking, message length, and the wording that carries tone. Every alias of one person resolves to a single consistent token, and each run can emit a SHA-256 receipt recording exactly what was removed. Mirror Veil does not claim anonymity: context can still identify people, so the cleaned file should be reviewed before sharing.
