Looks cool! Are you planning on adding more customization to be able to influence the AI? See https://bettergpt.chat/ (it's also open source and uses API in the browser). Basically with that frontend you can control the role of all messages (e.g. add system messages) and also edit them all to better influence the AI in some cases.

Editing the prompts (which are currently submitted via the system message similar to your linked app) is a great idea. I'll add it to the to-do list :)
