Everyday use I could see myself reaching for this when I’ve written something that technically makes sense but sounds awkward. Being able to fix it right there without opening another tool feels genuinely convenient.

"privacy-first" and "browser extension that rewrites text on any site" don't usually go together, most of these ship your selection to an API somewhere. is the model actually running locally in the extension, or is "privacy-first" here meaning no logging/retention on your servers rather than no network call at all? that distinction matters a lot for anyone pasting client emails into the rewrite box.
