Show HN: Turn spoken thoughts into system design diagrams (github.com)

A new productivity tool called Lucid has been unveiled, allowing users to convert spoken thoughts into structured system design diagrams and notes. Designed to operate hands-free or with one hand, Lucid runs locally on a user's computer, ensuring privacy and efficiency while creating organized content like headings, lists, and diagrams in real-time. Users dictate to an input box, which then transforms their speech into formatted text and visual elements, ultimately typesetting a polished PDF. This innovation is particularly significant for the AI/ML community as it leverages local models, such as Qwen 3.8, to enhance accessibility and usability in technical design workflows. The tool guides users through a three-phase approach for building diagrams, facilitating easy edits and maintaining a history of changes. This local-first architecture not only minimizes costs but also allows for immediate feedback, making it an ideal tool for educators and professionals who prefer verbal communication for design and learning. Lucid supports multiple operating systems and is built on open-source platforms, inviting collaboration and improvements from the community.
