Built my first Chrome extension — AI that works with a keyboard shortcut and copies the answer to your clipboard. Looking for brutal feedback.

Spent a few months building this solo. It's called Helpi and the core mechanic is: select any text → keyboard shortcut → answer is in your clipboard. That's it. No popup, no sidebar, no UI to deal with.

The shortcuts:

• ⌥⇧A — explains/answers selected text

• ⌥⇧G — fixes grammar

• ⌥⇧S — summarizes

• Smart action — AI decides which of the above to apply automatically You can also create custom shortcuts (e.g., bind ⌥⇧1 to "translate to Spanish" or ⌥⇧2 to "explain like I'm 5"). Technical things I'd love feedback on specifically:

• The clipboard approach — some users love it (zero UI interruption), others expected a popup. Which do you prefer?

• Content script injection — I inject on every page. Any sites where it breaks for you after installing?

• The shortcut combo — ⌥⇧A feels natural on Mac. On Windows/Linux it's Alt+Shift+A. Is that comfortable? I'm 19, this is my first published extension, live on Chrome Web Store. Any feedback — UX, technical, even just "this already exists better here" — genuinely helpful. (link in comments)
