Hello HN. I thought it would be cool to have something like Github Copilot that works in any application.<p>So I made this thing where you can select the text you're typing (in any application) and press a shortcut key (Ctrl + . by default, not configurable yet) to include the selection into a prompt, send to an LLM (right now it's only OpenAI), and possibly insert the response back into the application you were in.<p>Also the same interface can be used to query indexed documents. Eventually I would have it watch a directory for changes so any documents added there are indexed automatically but right now indexing has to be done in settings screen.<p>I would appreciate your thoughts! You can test with your own OpenAI api key or you can register a test account and use my api key.
