I did an experiment with ChatGPT for this recently.

I run my blog using Django, and the Django Admin has a feature where you can construct a link to an "add post" page with query string parameters that pre-populate that form.

I set up a GPT (a custom ChatGPT with a system prompt) with these instructions:

    You help me write new items for my link blog
    by generating URLs to the Django admin that
    prefill the new blog entry form

    The URL you generate always starts like this:
    
    https://simonwillison.net/admin/blog/blogmark/add/?use_markdown=1

    Then you add more URL encoded pairs:

    link_title is the title of the link
    link_url is the URL
    slug is the URL slug used on my site - it
    should be the title in lower case with dashes
    instead of spaces and with stop words removed
    via_url is optional - it’s the via URL
    via_title is optional too
    commentary is the longest field - it’s the
    markdown for my blog entry. It should usually
    include more markdown links.

    I will paste in notes, you turn them into a
    link to this URL

Now I can copy and paste rough notes from my iPhone notes app - with the title of a link, the URL, a bunch of notes and maybe a "via XXX" text at the bottom - and it will generate a working link like this one:

    https://simonwillison.net/admin/blog/blogmark/add/?use_markdown=1&link_title=Zero-latency%20SQLite%20storage%20in%20every%20Durable%20Object&link_url=https%3A%2F%2Fblog.cloudflare.com%2Fsqlite-in-durable-objects%2F&slug=zero-latency-sqlite-storage-durable-object&commentary=Kenton%20Varda%20introduces%20the%20next%20iteration%20of%20Cloudflare%27s%20%5BDurable%20Object%5D(https%3A%2F%2Fdevelopers.cloudflare.com%2Fdurable-objects%2F)%20platform%2C%20which%20recently%20upgraded%20from%20a%20key%2Fvalue%20store%20to%20a%20full%20relational%20system%20based%20on%20SQLite.%0A%0AThis%20is%20a%20fascinating%20piece%20of%20distributed%20system%20design%2C%20enabling%20a%20really%20interesting%20way%20to%20architect%20a%20large%20scale%20application.%0A%0AThe%20key%20idea%20behind%20Durable%20Objects%20is%20to%20colocate%20application%20logic%20with%20the%20data%20it%20operates%20on.%20A%20Durable%20Object%20is%20a%20code%20instance%20on%20the%20same%20physical%20host%20as%20the%20SQLite%20database%20that%20it%20operates%20on%2C%20resulting%20in%20blazingly%20fast%20read%20and%20write%20performance.

That example won't work for anyone who isn't me because you need to be signed into the Django Admin to view the link, but here's a screenshot of what I get:

I haven't been using it though, because it takes too long for ChatGPT to type out that URL one URL-escaped character at a time.
