Prompt Anywhere v2

Open prompt-anywhere in Script Kit

It's a completely overhauled version of the original. There was too much funkery (real word) that could happen by letting chatgpt just spew characters via keyboard.

V1 still will exist as quick-prompt.js and will live under the deprecated folder with a disclaimer about the funk mentioned above and use at own risk, etc. I'll still be using it, because it's pretty fun :)

Anyhow, This is a "pre-release" and will be added to my kenv soon

There are a couple things I still need to work out, like how the heck to stop the token stream on escape and some more QOL, but I really happy with it. I used it all week in my workflow and it's really a game changer.

Feedback, critiques, or bad puns are welcome.

Anyhow, set forth and be awesome.

# Prompt Anything
Highlight some text and run this script to prompt against it.
Useful for summarizing text, generating a title, or any other task you can think of.

## Usage

- Highlight the text you want to prompt against
- Run the script via shortcut or command palette
- Input your desired prompt
- Wait for the AI to respond
- Select one of the options
* Retry - Rerun generation with option to update prompt
* Edit - Edit response in editor
    - On editor exit the message is saved to the clipboard
    - On editor submit the message is pasted into the highlighted text
* Copy - Copy response to clipboard
* Paste - Paste response into highlighted text
* Save - Save response to file (not working)
## Example
- Highlight: 'Some really long passage in a blog post'
- Run Script
- Prompt: `Summarize this passage in the form of Shakespearean prose`
- Waaaaait for it...
- Get a response from the AI
- Select an option
- Rinse and repeat
