For Chrome and Edge on macOS and Windows. The assistant downloads, verifies and extracts the extension, and sets up future updates automatically.
Run the assistantChoose a locationFollow the illustrated guide
01 Install the assistant, then open it
macOS: open the PKG from the official website. At “Select a Destination”, choose Macintosh HD (your startup disk) and continue. This screen selects a disk for the assistant, so it is normal that you cannot choose a specific folder here.
Now: macOS InstallerMacintosh HD → ApplicationsInstalls the assistant itself
After installationOpen Page Annotator InstallerFinder → Applications
After the PKG finishes, open the assistant. In Finder → Applications, double-click Page Annotator Installer. You can choose the extension folder in the next step.
Windows: extract the assistant ZIP and open 安装更新助手.cmd. No Python or Node installation is needed. Windows code signing is pending and SmartScreen warnings may appear.
02 Choose the extension folder in the assistant
Documents is a convenient choice. The assistant creates a Page Annotator folder there and downloads and verifies the extension from the official website. You do not need to download or extract the extension ZIP yourself, or copy an extension ID.
Already using the extension? Select the original folder currently loaded by your browser. The assistant connects to that location without overwriting existing files or clearing browser data. Do not move to a new folder as a way to update the old installation.
03 Load the extension using the illustrated guide
The assistant opens a guide showing your exact folder path and illustrated instructions. In Chrome or Edge, enable Developer mode, click Load unpacked, and select that folder.
Installation is complete when the “页面标注 Page Annotator” card appears. You must complete the initial browser loading step yourself; file preparation and updater configuration are already done.
For future updates, just click the button
In the extension, open “更新” (Update), then click “立即更新” (Update now). Downloading, verification, backup and installation are automatic. Restart your browser when finished. There is no need to rerun the installer or export JSON.
Automatic backups are stored in .pa-updater inside the original extension folder. Keep the same installation location, and do not uninstall the extension to update it.
