The problem

Chats get saved. Make sure yours are anonymous.

Pasting is permanent

Once your SSN, bank details or test results reach a chatbot, you can't take them back. Depending on the service and your settings, chats can be stored, reviewed by people or used to train the AI.

Blacking out breaks the answer

Delete the details by hand and the AI loses track of who is who. You get vague advice and fill in the gaps yourself.

Privacy tools are built for companies

Most cost thousands and need an IT department. Hushtag is a Chrome extension that works the moment you paste, for $4 a month.

How it works

Paste. Ask. Restore.

You paste Daniel Okafor, the AI sees #PERSON_1, you get Daniel Okafor back.
1 · Paste

Paste or drag in, as usual

Hushtag turns private details into hashtags before the chat site receives them. A small note tells you what it hushed.

Patient: #PERSON_1
Member ID: #HEALTH_ID_1
2 · Ask

The AI works with hashtags

The same detail always gets the same hashtag, so the answer still makes sense, even across follow-up questions.

Ask Dr. #PERSON_2_LAST whether #PERSON_1_FIRST needs thyroid medication.
3 · Restore

Get the real answer back

Press Alt+Shift+S, or right-click the answer and choose Restore with Hushtag. Real names and numbers go back in.

Ask Dr. Pierce whether Jessica needs thyroid medication.

Working from a file? Open a PDF, Word or Excel file, or a photo of a form, in the Hushtag web app. It makes the masked copy for you, right in your browser.

FAQ

Questions people ask first.

What's a hushtag?

A hashtag that stands in for something private. Hushtag swaps your name for #PERSON_1, your SSN for #ID_NUMBER_1, your address for #ADDRESS_1, and so on. The AI works with the hashtags, then Hushtag swaps the real details back into its answer.

Is there a free version?

Yes, on this website. Paste any text into the web app and it hushes it for free, anytime, so you can copy the safe version into any AI chat. The Chrome extension, which hushes as you paste right inside ChatGPT, Claude and the rest, comes with Personal: $4 a month or $29 a year. Personal also adds whole files, locked keys and the Android app. Pro ($79 a year) covers up to 3 people.

Does my document ever leave my device?

No. Hushtag reads and masks text on your computer or phone. Only the masked copy reaches your AI tool. See where your data goes.

Does it catch everything?

No tool does. ID, account and card numbers are caught very reliably. Names are harder, so Hushtag also looks for names that aren't ordinary words and lets you add your own list of names to always hush. Look over what it masked before you send.

How do I restore the answer?

Press Alt+Shift+S (or click the Hushtag icon) and paste the AI's reply into the panel. Or select the reply, right-click and choose Restore with Hushtag.

What's the difference between Personal and Pro?

Personal is for one person: the Chrome extension, plus whole files (PDF, Word, Excel, scans and photos of forms) in the web app, locked keys so you can restore an answer days later, and the Android app. Pro has all of that for up to 3 people, plus priority support. It's built for small offices. Need more than 3? Buy another Pro plan.

Ask AI anything. Tell it nothing.

Works in ChatGPT, Claude, Gemini and 5 more, in Chrome, Edge and Brave. From $4/month.
