# My blog engine is now privacy-first

> I rebuilt my blog engine to make sure that everything you see here is transparent, private, and free from third-party tracking.

A quick behind-the-scenes update on the blog engine itself. Since I launched this thing I've quietly added a bunch of features, and most of them share a theme: being transparent about how the site is made, and not leaking your data to third parties in the process.

I built this engine myself, with AI help, which is rather the point. So none of this is a changelog - these are choices I made on purpose. Quick tour of what changed.

### A real transparency label

Every page now carries a small AI transparency label in the footer. It says, in plain terms, what a human did and what the AI did on this site - ideation and the actual writing are mine, the AI helps with engine development and polishing. This matches the whole spirit of the [AICare toolkit](https://unprompted.dirkprimbs.de/posts/aicare.md) I wrote about earlier: if I'm going to use AI, I should say so, out loud, where you can see it.

### Automatic alt text for images

Every image I drop into a post now gets a written alt text - the description a screen reader reads aloud, and the thing you see if an image fails to load. It's generated automatically at build time by a vision model, but only when I haven't written one myself. If I write my own, mine stays.

The point is accessibility. I was forgetting to write alt text by hand, so I made the engine refuse to forget.

### YouTube embeds that don't spy on you

When I link a YouTube video, it now shows up as a proper playable embed instead of a plain link. But it does NOT load YouTube's player - or its cookies, or its tracking - until you actually click play. Before that it's just a thumbnail served from my side.

So you can read a post with a video in it and YouTube never knows you were there unless you decide to watch.

### Comments, powered by Mastodon

The big one. Posts can now have a comment section - and it's just Mastodon.

When I publish something, the engine posts a toot linking to it. Any replies to that toot become the comments under the article. No comment database, no Disqus, no third-party embed watching my readers. The comments load from Mastodon only when you click a button, and I sanitize everything before it touches the page.

If you want to comment, you reply to the toot. Your comment lives on your own Mastodon account, on your own instance. I don't own it and can't hold it hostage. That feels like the right way round.

Credit where due: I adapted this approach from Carl Schwan's excellent write-up, ["Adding comments to your static blog with Mastodon"](https://carlschwan.eu/2020/12/29/adding-comments-to-your-static-blog-with-mastodon/). I changed a fair bit to fit this engine, but the core idea is his.

### Smaller things

Link previews: posts now generate a proper preview card when shared (the image + title + summary box you see on Mastodon, LinkedIn, etc). If a post has its own image it uses that, otherwise a default.

Images are now self-hosted too - anything I reference gets copied into the site instead of hotlinked, so nothing breaks or leaks later.

The common thread, if there is one, is that I'd rather the site be a little more work for me and a lot more transparent with you. Next thing on my list is watching to see if anyone actually replies to that first toot.
