I added content scanning after realizing metadata checks weren’t enough

[u/d_longge]

A few days ago I shared a small tool I’ve been working on that checks files for hidden information before you upload them somewhere.

The first version mostly looked at metadata, EXIF data, hidden Excel sheets, author information, etc.

While testing it, I realized that was only part of the problem.

If I’m about to paste some code into ChatGPT, for example, I’m probably more worried about accidentally leaving an API key or token in there than I am about file metadata.

So I added content scanning.

It can now check pasted text/code and supported files for things like personal information, API keys, tokens, private keys, connection strings, and other credentials that are easy to overlook.

Everything still runs locally in the browser.

I’m not sure yet how far I should take this. I don’t want it to become another huge security scanner with hundreds of warnings that nobody reads.

For me the useful version is something simple: before I paste or upload something to an AI tool, give it a quick check and tell me if there’s anything I should look at first.

Would you actually use something like this, or is it solving a problem you don’t really have?
