Turn step-by-step tutorials into single-file offline interactive diagrams for easy sharing and demos

Problem: Developers making tutorials, docs, or demos need interactive step-by-step diagrams, but existing tools are either online-dependent or complex. Someone launched Yantra exactly for 'Interactive step-by-step diagrams as one offline HTML file,' showing demand for simple, self-contained solutions.
Solution: A desktop or web tool that imports images/text, lets you create step-by-step interactive diagrams with annotations and connectors, and exports a single HTML file viewable offline; embeddable in any webpage or doc.
Users: Technical writers, educators, product managers, open-source maintainers
MVP: Upload images and add step annotations; drag to reorder; export as a self-contained HTML file; provide simple theme templates.
Revenue: Free tier with watermark; one-time Pro $29 removes watermark and supports custom templates; team license.
Why now: Remote collaboration and async demos are growing, and offline single-file sharing is more private and reliable; indie developers can build fast.
