Gloss

AI agents tell people things like add your API key to theenv file all day, and a lot of people just do it, without knowing what aenv file is. Gloss is for that moment. Highlight any text in any app, press a hotkey, and it explains what the thing is, why your AI wants it in your project (it can read your screen), what yes or no changes, and if you can undo it. One tap translates the card, Bangla by default. Free, open source, no accounts, your own key. There's also a pet.
