Could you build this?
Yes It is a browser extension that reads DOM comments and uses the Chrome built-in window.ai / Gemini Nano API to rewrite text in place.
Discussion
1 comment analyzed.
Concerns raised: High system requirements (22GB disk, 4GB VRAM, 16GB RAM), Chrome 138+ desktop only, limited language support, First rewrite per session has slow warmup time
Feature requests: Support for additional languages beyond en/es/ja, Mobile or cross-browser support
