My most used is to copy text where the formatting has been stripped, the bookmarklet prepends formatting instructions, and then I paste the whole thing into claude which sorts the formatting.
Me thinks I've underestimated what can be done with these.
Absolutely. If your account has access to the data, you can basically rewrite a website using a bookmarklet.
I wanted a friends feed in eBird (its social model is inscrutable) and ask Claude to make a bookmarklet that showed the most recent lists of my friends sorted chronologically. One shot and done.
Our internal corporate CRM is siloed data queries spread across overlapping views. I have a bookmarklet overlay my own interface on top and fetch data using the existing session token. (which is transparent/automatic - your browser just hangs on to the session cookies for the fetch calls)
The authenticated-page support is what caught my attention. Being able to grab an internal dashboard or admin UI and get editable Figma layers from it could save quite a bit of tedious recreation work.
This is cool. How do you implemment it?
I use bookmarklets for a number of simple things.

Not much to add here but wanted to say I very much support having more people show video demos when they do show hn.
