VibeMark is a Markdown, HTML, and SVG reader built for reviewing AI-made demos on your phone. When Codex or another AI tool generates an HTML/SVG demo, README, product spec, or visual page from your desktop workflow, you can open it directly on mobile and inspect the real rendered result without going back to your computer. Turn on Review mode to tap a specific area of the page, leave a change request, or propose permitted HTML/SVG source edits. With Review Sync, your comments and source edits can be handed back to a configured Codex workflow; you can also export a handoff packet as a fallback. VibeMark is also useful for everyday Markdown, HTML, and SVG reading: GitHub-style tables, LaTeX math, Mermaid diagrams, syntax-highlighted code, in-document search, table of contents, light/dark/sepia themes, and image export are all supported. Privacy comes first by default. Files render on device and work offline. Remote content is blocked until you allow it. No accounts, no tracking, no ads.
