Show HN: Lexicon a free Grammarly alternative, local writing assistant

Lexicon, a free, open-source desktop writing assistant that runs entirely locally, has been released on GitHub under an MIT license. The app provides grammar checking via LanguageTool and AI writing tools such as rewriting, tone shifting, and summarizing using a bundled quantized model or an optional Ollama server, with no account or internet connection required. Available for Windows and macOS, Lexicon aims to be a privacy-focused alternative to cloud-based services like Grammarly.

Lexicon is a rich-text editor with grammar checking and AI writing tools rewriting, tone shifting, and summarizing that run entirely on your machine. No account, no API calls, and nothing uploaded. Grammar/spelling/punctuation checking runs through LanguageTool locally; the AI tools run through a small quantized model bundled with the app via llama.cpp, or your own Ollama server if you already run one. It's a desktop app installer for Windows and macOS on the releases page, with an in-app auto-updater. Check it out: https://lexicon-writer.pages.dev/ https://lexicon-writer.pages.dev/ MIT licensed.
