Textmode Overlay por humanbydefinition

Click the extension, pick a canvas or video, and a live ASCII/textmode layer appears directly on top of the original media - aligned, adjustable, exportable, and removable at any time.

Built with textmode.js.

─── HOW IT WORKS

1 Click the [Textmode Overlay] icon in your toolbar
2 Click "select media" in the overlay panel

─── PRIVACY & PERMISSIONS

Textmode Overlay runs only after you click it. It works on the active tab, keeps processing local in your browser, and does not collect data.

Permissions used:
▸ activeTab operate only on the tab you invoke it on
▸ scripting inject the overlay runtime after your click

─── IMPORTANT NOTES

Some cross-origin, tainted, or protected media cannot be sampled due to normal browser security restrictions. The extension will show a clear message when this happens.
