Hey Product Hunt! 👋

I'm Antonio, a software engineer and independent developer from Italy 🇮🇹

I've built and shipped other software products, and today I'm excited to introduce Redatch, my latest macOS app.

Why I built it

Like many developers, I use ChatGPT, Claude and other AI tools every day. I frequently share screenshots, invoices and documents, but I kept running into the same problem: they often contain information I don't want to share.

Manually editing every screenshot felt unnecessarily slow.

I wanted something that felt like a natural part of macOS, rather than another complicated tool.

So I built Redatch.

You can drag files directly onto your Mac's notch, let the app detect sensitive information, review the results and get redacted copies ready to share.

Everything is processed locally, and your original files remain untouched.

One important design decision: automatic detection isn't infallible. That's why Redatch lets you review what it finds before redacting anything.

A few things worth mentioning:

Native macOS app, built for Apple Silicon.
Supports screenshots, PDFs, Word and Excel documents.
Detects IBANs, emails, phone numbers, payment cards, API keys and more.
First 10 files are free, with all features.
$9.99 one-time purchase. No subscription.

I'd really appreciate feedback from the Product Hunt community, particularly on two questions:

What other types of sensitive information should Redatch recognize?
Would you find a notch-based workflow useful in your daily work?

Thanks for checking it out! 🧡
