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.

About Skillful

Skillful is a local-first desktop app for building reusable AI skills and agents as real folders, then installing them into Claude Code, Codex, Cursor, Copilot, Gemini, Junie, and opencode. Skillful turns prompts, agents, screenshots, scripts, and notes into a filesystem library you can inspect and maintain. Prompts, screenshots, scripts, and supporting notes live next to the skill that uses them. Keep `SKILL.md` and `AGENT.md` workflows in one library, with filters and badges that make the difference clear without splitting your workspace.
