Lexicon

什麼是 Lexicon？

I built Lexicon, a free, open-source desktop writing assistant. Clean grammar checking and text editing without sending your private drafts to cloud servers or paying monthly subscriptions. A rich editor includes LaTeX math, structured tables, code blocks, and clean PDF/Markdown exports. The app offers proofreading and 15 local text tools (Rewrite, Concise, Tone shifts, Summaries, Tables). It's completely free and open-source under the MIT license.
