I wanted to share a project I’ve been working on called Lexicon. It’s a free, open-source, and privacy-focused writing assistant designed as a local alternative to cloud tools like Grammarly.

I decided to build a proper native desktop app using Rust and React.

• Lexicon has a rich editor that includes LaTeX math, structured tables, code blocks, and clean PDF/Markdown exports.
• Offers proofreading and 15 local AI actions, including Rewrite, Concise, Tone shifts, Summaries, and Tables.
• Completely free and open-source under the MIT license.

Let me know if you have any questions or feedback!

Built a local-first writing editor using Tauri v2.

• 100% Offline Grammar & Proofreading: Powered by a local LanguageTool engine
• 15 On-Device AI Tools: Rewriting, tone shifts, summaries, and structured tables via local quantized GGUF models (llama.cpp)
• Ollama Integration: Auto-detects local Ollama instances or uses a bundled local model
• No Cloud / No Accounts: Everything stays strictly on your device
• Full Desktop Packaging: Compatible with Windows and Mac

I built this because I wanted an offline Grammarly alternative where my drafts never touch a cloud server. Let me know what you think!
