Canvas

Canvas is NevoFlux's runtime for rich, interactive output. When you ask the agent to build something — a dashboard, a calculator, a chart, a diagram, slides, or a video — it generates a Canvas artifact that opens in its own tab and runs live.

Creating a canvas

Just ask, or use the app skill:

/app a markdown editor with live preview

The agent generates the artifact and opens it at nevoflux://canvas/{id}. You can also open saved artifacts from Settings → My Canvas.

What a canvas can be

• HTML app — a single-page app.
• Multi-file project — React, Vue, or Svelte, bundled automatically (esbuild).
• Markdown, SVG, Mermaid diagrams, slides.
• Video compositions — rendered to MP4 (see the video skill).

Artifacts run in a sandboxed iframe for safety.

Working with a canvas

The toolbar lets you:

• Switch between Preview and Edit (a code editor).
• Copy the source.
• Export to many formats — Source, HTML, PNG, PDF, DOCX, SVG, Markdown, PPTX, XLSX, or a ZIP of the project.
• Share the artifact (end-to-end encrypted), and import a shared one via nevoflux://import/{share_id}.

Build apps that talk to the agent

Canvas apps can call back into NevoFlux — chat with the agent, store data, publish events, and run whitelisted tools — through the NevoFlux SDK. The set of tools an app may run is governed by the tool whitelist.
