Relay

Chrome extension

A real, working Manifest V3 extension — download it and load it unpacked.

The floating panel, previewed

This is what appears on other websites once the Relay extension is installed — a static preview, not a live control.

Mock — not interactive

any webpage

any webpage, expanded

Chrome does not allow an ordinary website to draw on top of other websites — that overlay only exists once the extension below is installed. This page never pretends otherwise.

Install it locally

Six small files. Ten minutes, once.

  1. Create a folder named relay-extension.
  2. Download each file below into that folder, with its exact name.
  3. Open chrome://extensions, and turn on Developer mode (top right).
  4. Click Load unpacked and select the relay-extension folder.
  5. Pin the Relay icon, open any website, and look for the floating 📝 tab.

Permissions, plainly

  • storage — keeps your notes and the panel's position on your machine.
  • contextMenus — the right-click “Save to Relay Notes” action.
  • activeTab, scripting — insert a note into the field you clicked, and recover on tabs the panel missed.
  • host permissions (all sites) — the floating panel and Paste both need the page you're actually on.
What it will not do: Chrome itself blocks extensions on chrome:// pages, the Web Store, and most PDF viewers. Relay does not fake an overlay there — Paste simply falls back to your clipboard.
