Even just in this listing, I would advocate against titling it "yet another...". It makes it harder to read past and understand a unique selling proposition (USP).

It looks like you do capture something unique, the ease of using "contexts" for the predefined prompts is component of user experience. I've defined custom prompts in another desktop app, but I never remember to use them.

- I would encourage you to walk through the workflow on the homepage:

  - Hot-key summon (I'm assuming)
  - Context: translation, terminal help, web help, general assistant——select with tab
  - Quick, desired reply with minimum of typing.

- Crisp, shorter language: "Prompt fast", "$(printf '%s\n' {have,keep}\ your\ {favorite,common,best}\ {contexts,prompts,tasks}\ ready)"

- It might be worth explaining, and explaining the unicode symbols for the system prompt and prompt prefix at the top of settings. Or having a descriptive prototype prompt.

  [Context name / Prompt title]
  [System prompt]
  [Prefix preset for task prompt]

It seems like user education is a net benefit.

- A workflow that coaches ("prompts") someone though adding prompts could be a useful addition.

Unfortunately I'm on an older intel MBP and can't install macOS 13 Ventura, and so I can't try out your app. Good luck!.
