PowerScroll canvas with notebook hierarchy, independent scrolls, markdown, and an editable architecture diagram
01

Actually yours

No account, cloud database, or proprietary vault. Your notebook is the file on your disk.

02

Visual and structured

Sections and pages outside; markdown, ink, images, shapes, and independent scrolls inside.

03

Agent-readable

A local MCP bridge lets agents work in the visible notebook instead of hiding results in a chat transcript.

THE WHOLE MODEL

The editor travels with the notebook.

Press Ctrl+S and PowerScroll writes the current editor, workspace, images, drawings, and extensions into one self-contained HTML file. Reopen it to continue. Send a copy and the recipient receives an editable notebook—not a flattened export.

A SHARED VISUAL WORKSPACE

Let the agent do the layout work. Keep the canvas in your hands.

Agents can read pages, write markdown, insert images, manage scrolls, and turn PlantUML, Mermaid, SVG, or draw.io into ordinary editable canvas objects.

PRIVACY BY ARCHITECTURE

No cloud promise to trust. No cloud dependency to begin with.

Normal editing runs in your browser and stores the notebook where you choose. Update checks and optional extensions contact GitHub. The agent bridge is disabled by default and uses a loopback connection on your own machine.

Before you open the file

Does the live demo upload my notes?

No. The hosted build runs in your browser. Download or save your notebook to keep it.

Can I open an old PowerNote notebook?

Yes. PowerScroll preserves the embedded data format, internal links, browser storage, and bridge protocol used by existing PowerNote files.

Which browser should I use?

Chrome and Edge provide direct disk save and autosave through the File System Access API. Firefox and Safari use a download fallback.

Is it really open source?

Yes. PowerScroll is MIT licensed. The source, release tag, committed standalone build, and SHA-256 release digest are public on GitHub.
