About Lexicon
Lexicon is a free, open-source Grammarly alternative and local-first writing app for Windows, macOS & Linux with offline grammar checking, local AI rewrites, and clean PDF export. No accounts. Proofreading, Lex, and export are built in, not bolted on. Run inline checks for spelling, grammar, and style with 1-click Apply. Built-in checks run on your CPU; external AI servers are optional and user-configured. Use a downloaded local model on supported builds or a server that you configure.
