ArcPanel

ArcPanel is a page-aware side panel for instant browser actions.

Select text, paste data, or use the current page to open the right action without leaving the tab.

ArcPanel helps developers move faster on the page they are already using:

Format JSON beside the current tab
Inspect JWTs without pasting tokens into another site
Test regex patterns live
Encode or decode URLs and Base64
Pick colors from the current page
Count words and reading time from selected text
Reopen clipboard history
Capture a screenshot frame or build a GIF
Core actions are local-first and useful without an account. Page access is used to read the active tab context, selected text, and page-aware inputs when you ask ArcPanel to act on the current page. AI is optional.
