HelpNDoc Project Importer

Introducing a new HelpNDoc project importer that makes it much easier to reuse and consolidate work across multiple projects. Authors can selectively import topics, library items, and keywords from other HelpNDoc projects, with fine-grained options to bring in only those items that are actually used or keywords that are directly related to imported topics. This streamlines project migration and ensures that only relevant, consistent content is carried over. See: HelpNDoc project importer 

New single-page Markdown template

A new publishing template has been added to export entire HelpNDoc projects as single-page Markdown files. In addition to the project's content, the generated file includes AI-friendly metadata such as project details (name, author, version, etc.) and per-topic information (IDs, captions, help contexts). This makes the Markdown output more useful not only for developers and content pipelines but also for large language models and other AI tools that can leverage structured metadata. See: Single page Markdown documentation settings 

Track incoming links in topic analyzer

The Topic Analyzer now shows all incoming links to a given topic, helping authors quickly identify which other topics reference it. This makes it much easier to track cross-references, spot unused or overly linked topics, and maintain a consistent documentation structure by revealing how content pieces relate to one another. See: Analyzing incoming topic links 

Picture IDs and class names

Images in HelpNDoc projects can now be assigned optional IDs and CSS class names, which are carried through into all HTML-based documentation exports. This enhancement allows developers and designers to apply precise styling, interactivity, or linking behavior to images in generated documentation, increasing flexibility and control in web output. See: Working with pictures 

Copy and paste topic content as Markdown

Topic content can now be copied and pasted as Markdown, making HelpNDoc much more compatible with external Markdown editors and workflows. Authors can quickly transfer formatted content into a plain text, portable syntax that integrates seamlessly with modern publishing pipelines and collaboration tools.

Multiple topic selection in TOC

The table of contents now supports multi-selection of topics, enabling authors to reorganize, move, or delete groups of topics at once. This significantly speeds up large-scale content management tasks and makes structuring complex documentation projects more efficient and intuitive. See: Managing the table of contents 

Added support for favorite locations

Users can now save up to nine favorite locations within their documentation project, including both the current topic and any selected content inside it. These favorites can be instantly recalled through keyboard shortcuts or the ribbon toolbar, providing a fast way to jump back to commonly edited sections or specific text ranges without losing context. See: Set and access favorite topics
