Show HN: CountermarkAI – Protect your website from AI Bots

Hi HN,

I built CountermarkAI, a lightweight anti-scraping & bot-detection tool for content creators and website owners. It’s designed to help protect your work from unauthorized scraping and AI training, that repurposed your work without permission.

How It Works:

Use Hashtag – Creators add a unique hashtag to their content as a declaration of ownership.

Protect Website – For those running your own sites, simply add a small snippet to your <head>. The protect.js script works asynchronously by sending metadata from every page load back to our servers, logging requests, and flagging known AI-training bot user-agents (such as CCBot, GPTBot, ClaudeBot). If a bot is detected, it outright replaces the page content with “AI bots are forbidden on this site. The snippet has a hidden image that no browser will load but some bots may be tricked into requesting it.

Dashboard - Once you sign up, you can see all the bots that entered your domain and their IPs. So you can block then by IP.

Looking ahead, I'm planning an API rollout that will let you automate bot and IP inquiries and allow push request metadata directly from your server for seamless integration with your existing systems.

I’d love to hear your feedback on usability and any features you think might help further secure creative work against bot scraping. Thanks for taking the time to check it out!

Cheers, Setas
