I built Heartbeat.page for myself.

At my office, we use Slack and Teams, but honestly no one actually checks a digital status before they walk over to your desk.

I keep a QR code on my desk with a note that says "What I’m up to." Anyone can scan it to see if I’m in a deep-focus session or free to chat. I can update it from anywhere just by sending a quick email to a custom address. (There is a 'Download QR Code' icon on the page to make this easy).

I’ve also started putting the link in my email auto-replies. Standard OOO messages are usually static and boring, but this makes them a bit more dynamic/useful.

You can use it for all sorts of things, like notice boards etc. You can create up to 2 pages per email address.

I’m curious to know if you find this useful or how you’d use a simple status page like this. Thanks!

The biggest leverage in LLM application development is not model selection or prompt engineering — it is input preprocessing. Clean, structured input consistently produces better output regardless of the model.

I imagine the biggest challenge in something like this is to actually get people to take the action to check the site. Have you seen people actually visit the site from the QR code?

Love this. Elegant and simple.

what is the purpose?

lol?!
