StopNCII and hash tools: free protection every creator should know

There is a free tool that stops participating platforms from ever letting your images be uploaded in the first place. It is called StopNCII, and every creator should know it exists — even our customers.

Here is how it works. You pick the images or videos you want protected, on your own device. The tool creates a digital fingerprint — a hash — of each file. The files themselves never leave your phone or computer; only the fingerprints are shared.

Partner platforms check uploads against those fingerprints. If someone tries to post a matching file, it is blocked or flagged for review before it spreads.

The limits matter too. StopNCII only works on platforms that take part, and only for files you fingerprinted. Screenshots, re-recordings and edited copies can slip past hashes. It is a strong first wall, not the whole castle.

Our honest advice: enroll your most important content in StopNCII for free, whether or not you ever pay us. Then, for everything hashes can't catch — pirate sites, search results, Telegram, re-uploads — that is where a scanning and takedown service earns its money.
