Grammarly

Build me a personal writing checker to replace Grammarly. Requirements: - Grammar engine: LanguageTool running locally via its official Docker image; grammar checks never leave my machine. - A local web page (Node + Express, binds to localhost): paste text, see LanguageTool issues underlined with hover explanations, click a suggestion to apply it. - An LLM rewrite pane (key in .env) with three buttons: tighten, friendlier, formal. Show a diff against my original before I accept anything. - A personal dictionary file (dictionary.txt) of names and jargon to never flag, passed to LanguageTool on every check. - CLI mode: `check <file.md>` prints issues with line numbers, exits nonzero if any, so it can run as a git pre-commit hook on docs. - Everything local except the optional LLM call; no accounts, no telemetry. - Out of scope: a browser extension and inline suggestions inside Gmail, Docs, or Slack. This is a destination I paste into, that is the honest trade against Grammarly. - README: Docker setup for LanguageTool, the roughly 1 GB of RAM it wants, and where the LLM key goes.
