RepoWiki

A Chrome extension that adds a split button to every GitHub repository page, letting you instantly open any repo in your preferred AI wiki provider — DeepWiki, CodeWiki, Zread, or Readmex.

Features

• Split button on GitHub repo pages — click the left half to open the pinned provider directly, click ▾ to pick another
• Pin any provider — click the pin icon in the dropdown to change your default; saved to sync storage
• 4 providers built-in, all enabled by default

Provider	URL pattern
DeepWiki	deepwiki.com/<owner>/<repo>
CodeWiki	codewiki.google/github.com/<owner>/<repo>
Zread	zread.ai/<owner>/<repo>
Readmex	readmex.com/<owner>/<repo>

• Dark mode — matches GitHub's light/dark theme automatically
• Rainbow hover effect on the button
• Live sync — toggling a provider in the popup immediately updates the page button
• Popup — manage which providers are enabled; the pinned provider shows as a prominent quick-open button

How it works

On every GitHub repo page (github.com/<owner>/<repo>) the content script injects a split button into the repository action bar alongside Watch / Star / Fork.

• Left button — opens the pinned provider in a new tab
• Chevron button — opens a dropdown listing all enabled providers; each row has a pin icon to change the pinned provider

Provider enable/disable state and the pinned provider are stored in chrome.storage.sync, so settings follow you across devices.
