Hey Product Hunt, I’m Göktuğ. I built Unformation because I wanted to use AI with client documents, but uploading a confidential file to another service just to remove sensitive details felt backwards to me.

Unformation does the anonymizing in your browser. You open a document (Word, PowerPoint, Excel, PDF, or plain text formats like TXT, Markdown, CSV, JSON and HTML), choose what to replace, whether that’s an email address, a company name, an account number, or a term specific to a project, and download an anonymized copy to give to whichever AI you use. The restore key stays on your device, so when the reply comes back you can put the original details back where they belong. It’s free and doesn’t need an account.

You can try it with your Wi-Fi off. Open the site once, disconnect, then drop in a document. The review and download steps work offline too. The optional AI detection also runs on your device, so if you want to use it, download the model before disconnecting.

This is a side project I made for my own work, and this is the first time I’m showing it to people outside my circle, so I’m genuinely curious how it holds up. I’d especially like to hear what you end up changing in the review step. Did it miss something you’d want removed, or flag something you’d want to keep? No need to share anything real, a made-up example is enough. And if something feels rough or confusing, please tell me. That’s exactly what I’m here to find out.

Thanks for taking a look!
