SideQuest

About

Go on a side quest with your Claude chats.

Highlight anything in a Claude reply and ask about it in a small side chat, without touching your main conversation. It runs on your own claude.ai account. No API key needed.

What you get:

A side chat for any highlighted text
Answers use context from where you highlighted it, not just the words themselves
Full markdown support, including code blocks and tables
Branch one highlight into more than one side chat
Drag and resize the panel from any edge. It remembers where you left it
Search past side chats from the toolbar
Open any side chat as a full claude.ai tab
Light and dark themes
Turn off sidebar saving, or delete any chat, whenever you want
It doesn't use a server. It doesn't collect data or store any keys. Requests go straight from your browser to claude.ai using your existing session.

To use it: highlight text in a Claude reply, click the SideQuest button, and go on a side quest!
