    That’s so interesting! I know a few of the individuals and really am curious on how they interact/work together. Cool stuff

    Content protection and accessibility are in direct conflict with most approaches. Working on making the a11y layer something I handle properly rather than just hoping CSS ordering …

    The goal is raising the cost from "curl + cheerio" to "write a custom decoder per site." Most scrapers move on to easier targets.

    The breadcrumb approach right now is simple invisible markers, not paraphrase-resistant watermarking. You're right that semantic watermarking that survives LLM rephrasing is the ha…

    Thanks, what phone/browser? I'll fix that.

    For content you want public, no.

    The TalkBack issue is useful feedback, thank you. I tested with NVDA and VoiceOver but not TalkBack on Android. If light mode is reading individual words instead of a continuous bl…

    For public knowledge sites this would be the wrong tool entirely. The use case is more like paywalled articles, proprietary product data, or premium content that companies paid to …

    The bar for reverse engineering dropped to "paste the HTML into Claude and ask it to decode." That's partly why the v2 roadmap moves toward techniques where the readable text never…

    You are more than welcome to do so. Please keep in mind the realistic goal is raising the cost of scraping. Most bots use simple HTTP requests, and we make that useless.

    Well the information is not to hide, quiet the opposite haha. There is a Demo page

    You are not wrong. But the use case I keep seeing is companies with proprietary content they spent real money creating, who don't want it showing up in someone else's training data…

    Font remapping is actually on the v2 roadmap. The reason v1 uses CSS ordering instead is it preserves screen reader access. Tradeoff is it's reversible (as another commenter just s…

    Comment #47351219

    Yep, that works. The data-o attributes are readable in the DOM so you can reverse it with custom code. That's in the threat model. The goal is raising the cost from "curl + cheerio…

    Comment #47351204

    Copy-paste breaking is intentional for protected content but it's opt-in per component, not whole-site. On the AI docs concern, fair point. To answer directly: I've confirmed the o…

    Comment #47350290

    Fair concern. obscrd actually preserves screen reader access. CSS flexbox order is a visual reordering property, so assistive tech follows the visual order and reads the text corre…

    Show HN: I built an SDK that scrambles HTML so scrapers get garbage

    Hey HN -- I'm a solo dev. Built this because I got tired of AI crawlers reading my HTML in plain text while robots.txt did nothing. The core trick: shuffle characters and words in …

    How are the costs calculated? Is it just US based or would you be able to apply this let’s say to germany or thailand?

    Exactly this! There needs to be some sort of reward for the user to keep up with checking in. I imagine something like tamagotchi where you have to feed a pet like creature that al…
