Good morning, programs! Today I'm sharing yet another example of Chrome's on-device AI features, this time to demonstrate a "Bluesky Sentiment Dashboard". In other words, a tool that lets you enter terms and then get a report on the average sentiment for posts using that word. I actually did this before (and yes, I forgot until about a minute ago) last year using Transformers.js: Building a Bluesky AI Sentiment Analysis Dashboard. I also built this for Twitter, before it went down the toilet, killed off API access, etc. etc., but I can't seem to find it in my archives so maybe I'm hallucinating. That being said, earlier this week I thought I'd try building this because honestly I had forgotten about my previous demo, but it gave me a chance to play more with Chrome's AI tooling. Interesting enough, in that post from last year I mentioned possibly adding Shoelace for UI which I actually did for this demo... so not a total waste of time, right? Let's get into it!
This weekend I had some fun building a little Astro site for RSS aggregation. It works by the individual user defining a set of feeds they care about and works with a server-side Astro route to handle getting and parsing the feeds. Here's a quick example. On hitting the site, it notices you haven't defined any feeds and prompts you to do so:
Yesterday I blogged about using PDF.js and Chrome's on-device AI to create summaries of PDF documents, all within the browser, for free. In that post I mentioned it would be possible to build a Q and A system so users could ask questions about the document, and like a dog with a bone, I couldn't let it go. Last I built not one, but two demos of this. Check it out.
You can take the man out of the PDFs, but you can't take the PDFs out of the man. Ok, I'm not sure that exactly makes sense, but with a couple years in me of working with PDFs, I find myself using them quite often with my AI demos. For today, I'm going to demonstrate something that's been on my mind in a while - doing summarizing of PDFs completely in the browser, with Chrome's on-device AI. Unlike the Prompt API, summarization has been released since Chrome 138, so most likely those of you on Chrome can run these demos without problem. (You can see more about the AI API statuses if you're curious.)
I write this in the midst of a huge ice event - which thankfully isn't so bad here in south Louisiana. We're very cold and rainy, but no real ice yet, which is good. The worst is coming in later tonight and the schools have already shut down, but thankfully I work at home so there's no need to get on the roads. Today is also the 26th birthday of my eldest child, which makes the age ranges of my little army (8 kids total) go from 10 to 26. Wow.
Back in November of last year I wrote up a blog post talking about a new (at the time) Google Gemini feature, File Stores: "Gemini File Search and File Stores for Easy RAG". In that post I discussed what it was, how it worked, and built up a simple example. You should definitely read that post first, but if you want the TLDR, here ya go:
