smudge.ai reimagines how you interact with AI by moving it out of a separate chat window and into the context menu of your browser. Highlight text on any page, right-click, and choose a command such as Summarize, Correct, Bulletize, Refine or Translate. The extension captures the selected text, pairs it with that command's prompt, sends it to OpenAI, and streams the result back inline.
The extension ships with 16 built-in commands aimed at everyday tasks: recapping a long article, fixing spelling and grammar, converting walls of text into bullets, polishing your writing and translating between languages. You can also create your own commands to automate repetitive work, or browse the command gallery to import commands other users have shared. Since July 2024 you can reply to the AI to ask follow-ups or request iterations on your original command.
