Overview
Dr.Explain is a specialized Help Authoring Tool (HAT) that leverages a proprietary visual analysis engine to automate the documentation of desktop and web applications. Unlike traditional screenshot tools, Dr.Explain analyzes the internal structures of an application's UI to automatically create numbered callouts and descriptive labels for buttons, menus, and input fields. In the 2026 market, it occupies a critical niche for enterprises maintaining legacy systems or complex desktop software where cloud-based SaaS documentation tools lack deep OS-level hooks. The platform supports single-source publishing, enabling authors to generate CHM help files, searchable Web Help, printable PDFs, and Microsoft Word documents from a single master project. Its 2026 architectural updates include an AI-driven content refinement layer that suggests technical descriptions based on UI element metadata, significantly reducing the manual labor involved in technical writing. While modern SaaS platforms focus on collaborative wikis, Dr.Explain remains the gold standard for creating structured, offline-accessible, and context-sensitive help systems integrated directly into software binaries.
