The software documentation consistency check agent automatically analyzes all user guides, installation manuals, technical documentation, and release notes. It identifies vocabulary inconsistencies (e.g. the same button named differently), functional contradictions between versions, obsolete references or even shortcomings in the description of functionalities. Its mode of operation is based on natural language processing and semantic comparison between different sections of documents or different software versions. The main users are technical writers, product teams, developers, and support departments who rely on documentation to support customers. The benefits include better consistency and reliability of content, a reduction in errors or misunderstandings on the user side, an acceleration of document update cycles and an overall improvement in the customer experience and the professional image of the software.
