# Products

Two macOS apps for working and writing with AI. Maro Writer grew out of Maro Portal's writing extension.

  ## [Maro Portal](https://marolabs.kr/products/maro-portal/)

  A local-first personal AI workspace for the Mac. Talk to Maro in one place, hand off work, and get it back reviewed. Every conversation, decision, and lesson stays as a record you can search and build on.

  ## [Maro Writer](https://marolabs.kr/products/maro-writer/)

  A co-writing app for long-form and serialized fiction. The AI answers from your story's own record, and nothing joins the manuscript until you adopt it.
