Partial A browser extension with an on-device grammar checker is buildable, but accurate spelling and grammar across 101 languages needs multilingual language models and linguistic datasets that vibe coding does not supply.
What it would actually take: The extension UI and text-field integration are standard browser extension work. The core is on-device NLP: quantized small language models (for example via WebAssembly or WebGPU) or rule-based engines like LanguageTool, with separate models or datasets per language. Quality across 101 languages requires NLP expertise, native-speaker evaluation data, and careful model size and performance tuning.
