At its core is a Component Content Management System that breaks documents into small, reusable pieces instead of managing full pages. This approach lets you update content once and see changes everywhere it appears.

Heretto works entirely in the cloud, so teams can access it anywhere with internet. It supports multiple languages, tracks all changes to your content, and lets many people work on the same documents without conflicts.
DeepDocs is a GitHub AI agent that maintains your technical documentation in perfect sync with your codebase. When you commit code changes, it scans your entire repository to find documentation that needs updates and makes the necessary changes automatically.
