Chrome Extension Overview

The Chrome extension is Downcity's web-context entry point.

It connects "the page you're looking at" with "the task you want an Agent to do", so you do not need to manually copy content, switch to chat, and reconstruct context by hand.

Best Use Cases

• You are reading an article and want an Agent to summarize, translate, rewrite, or extract actions
• You selected a small part of a page and want to ask a local follow-up question
• You want to send a page snapshot into an existing Channel Chat
• You want a browser-native way to hand a live page to a local Agent

Two Entry Points

1. Extension Popup

Best for:

• explicitly choosing an Agent
• writing a full task prompt
• reviewing page-level send history

2. Inline Composer

Best for:

• asking about a selected quote without leaving the page
• switching between channel dispatch and immediate inline execution in the page context
• starting from the live reading context
• using Cmd/Ctrl + U to open the page-level composer

What Gets Sent

Selection Mode

• the selected text
• wrapped as a Markdown attachment
• optimized for focused follow-up questions

Full Page Mode

• the strongest main/article content region
• multiple strong content roots merged when needed
• image references attached when they can be resolved

What It Does Not Do

• wait for the full Agent execution result inside the popup
• become a second Console UI
• replace the original chat/context where results are returned
