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 Telem

Telem AI builds infrastructure for AI agents: web search routing, web fetch routing, and agent observability. Agents are only as good as the substrate they run on. Telem AI builds the layer between your agents and the open web: routing every search and fetch to the best provider, and observing every step so you can trust what ships.
