Hi HN community!

I've created a Chrome extension and Node.js server combo that lets Claude use external tools (calendar, Spotify, etc.) from within regular browser conversations - without any API access.

## Why

Tool use is available in Claude via API, but I haven't found a way to use tools from the web interface.

Over a weekend I've created a PoC and spent the next few weeks polishing the details before sharing.

The architecture is modular, making it easy to add new tools. I've included detailed setup instructions in the repo.

## How it works

- The extension injects a content script onto claude.ai/chat pages

- A background script captures all Claude responses via Chrome debugger API

- When Claude generates XML tool tags (e.g., ...), the server executes the corresponding action

- Results appear as system messages that you can paste into your conversation, so that Claude is aware of failures etc.

Demo video: https://www.youtube.com/watch?v=j8lgsGurY1w

GitHub: https://github.com/BartlomiejLewandowski/claude-browser-tool...

## Tools currently supported

- Google Calendar (create events)

- Spotify (play music)

Would love feedback on the approach and ideas for other useful tools to add!

Hey HN, I wanted to share a project I’ve been working on: an AI tool that instantly detects your face shape and provides personalized recommendations for hairstyles, glasses, and makeup. I got the idea after noticing how tricky it can be to find styles that truly suit your unique features, and I wanted to make that process easier and more data-driven.

The tool uses computer vision to analyze facial features and classify face shapes, then matches them with style suggestions based on some geometric and aesthetic principles I researched. Building the AI model was a fun challenge—training it to accurately detect face shapes while keeping it lightweight for quick results took a lot of iteration. I also worked on making the recommendations practical and user-friendly.

I’d love to get your feedback! What do you think about using AI for this kind of personalization? Are there other features or use cases you’d find interesting? If you’ve worked on similar computer vision projects, I’d be curious to hear about your experiences too.

Looking forward to your thoughts!

Something worth saving in a programmable calculator, like Naismith's Rule [1] or calculating the day of week for any date [2].

I love RSS feeds - it’s how I keep up with all of my (tech) news. The big downside with RSS though? You get all the articles that are in the feed. And unless your RSS reader of choice offers built-in mute or filter functionality, you’re just stuck with those articles.

So I built RSSfilter.com, a service that filters public RSS feeds, and spits out a new RSS feed without the articles that match keywords or categories you’re not interested in.
