Discord Automation Keyboard App for Android

I'm looking for a simple Android app: a custom keyboard that acts as an automation tool for responding to messages, particularly questions, in Discord. Given my tight budget, the focus should be on implementing only the essential features, avoiding any unnecessary UI elements.

Here's how the app should function:

- The user copies a question from Discord.
- The custom keyboard sends this question to GPT-3, an AI model, to retrieve a quick answer.
- The AI-generated response is sent to the clipboard.
- The keyboard only has one button: to switch back to the regular keyboard.

The keyboard won't have traditional keys; it will simply trigger the automation. For instance, if the question is "What is the capital of France?", the answer should return as "Paris".

Skills and experience that would be ideal for this project:

- Good knowledge in Android app development.
- Experience working with GPT-3 or similar AI models.
- Understanding of clipboard functionalities in Android.

Please let me know if this is feasible and provide an estimated cost for this project, as I'm not very knowledgeable about app development.
