About

Features

Distraction-Free Notation

Start annotating and the toolbar quietly gets out of the way, so your canvas stays clear and your focus stays on the idea.

Annotate anywhere, stay aligned

Freely annotate, underline, and highlight on any webpage. Your notes stay locked to the content, even through fast scrolling.

Smart, flexible toolbar

Drag the toolbar anywhere on screen. It gently re-orients itself so it's always reachable, never covering what you're reading.

Styled text blocks

Type clean, focused text blocks right on the page — adjust alignment, size, and color in place.

Smart Snapshots

Capture exactly what you need. Copy, save, or print your annotated page, with Smart Bounds framing just your notes or the full viewport

Built for speed

Use intuitive keyboard shortcuts to switch tools, change colors, undo/redo, or capture a snapshot of your notes — all without leaving the keyboard.

Privacy First

Every note and mark stays on your device, stored locally in your browser. No tracking, no external servers — just your work.

Current Feature & Tool Limitations

You can move and scale text blocks, but you can't edit the content yet. If you need to fix a word, use Undo (Cmd/Ctrl + Z) and re-type. Fully editable text blocks are planned for a future update.

PencilKit locks your notes to the page at the time you draw them. They stay aligned while scrolling, but big changes to window size or display scaling can shift them slightly relative to the page.

PencilKit works on most of the web. It can't run on internal browser pages (like 'chrome://settings') or some system-restricted sites. Very complex 'app-like' sites (for example, document editors or chat apps) may sometimes conflict with the drawing layer.

Not yet. To keep your data private and the experience fast, everything is stored locally in your browser. Notes stay on the device where you created them and don't currently sync across machines.
