If your team is maintaining the same content across multiple documents, reformatting outputs by hand, or sending the same paragraphs back to translators every release cycle - you're paying the hidden cost of unstructured content management. Author-it solves this at the source. It's an enterprise CCMS (Component Content Management System) with over 25 years of proven deployment in industries where accuracy, compliance, and scale aren't negotiable: manufacturing, software and technology, utilities, medical devices, aerospace and defence, financial services, and government. The platform centres on a single Library - a relational content database where Topics (content components) are assembled into Books (deliverables) and published to any format from one source. Update one Topic, and every Book containing it reflects the change. No manual updates. No version drift. No missing the footnote that just changed your liability exposure. Key capabilities include structured authoring without DITA or XML expertise, component-level content reuse (customers regularly hit 60–90% reuse rates), built-in translation workflow with XLIFF export and intelligent change-tracking to reduce translator word counts, multi-stage Review & Approve with compliance audit trails, variant and conditional content for multi-product and multi-market publishing, and output to HTML5, PDF, Word, SCORM, XML, DITA, and AION. AION is Author-it's structured JSON publishing format - designed for direct ingestion by LLMs and RAG pipelines. It mirrors the full content hierarchy: books, sub-books, topics, metadata, resolved variables. This is what makes Author-it an AI Content Foundation, not just a content management tool. Your existing structured content becomes queryable, retrievable, and AI-ready without any additional transformation layer. Deployment is cloud SaaS. Implementation is services-led, with expert information architecture guidance included. Contact us @ author-it.com
