Copilot Session Search

Search across all your GitHub Copilot Chat session history from a single panel.

Features

• Full-text search across every Copilot Chat session you have ever had
• Results grouped by session, showing the workspace folder and session title
• Highlights matching terms inside each turn snippet
• Expand / collapse long responses inline
• Copy any turn to clipboard with one click
• Finds turns from active sessions (even ones not yet flushed to the database)

Requirements

• GitHub Copilot Chat must be installed and have at least one session
• Windows (this was not tested and likely does not work on Linux/Mac)

Usage

1. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
2. Run Copilot: Search Sessions
3. Type any term — results appear as you type

How it works

Copilot Chat stores session history in a SQLite database at:

%APPDATA%\Code\User\globalStorage\github.copilot-chat\session-store.db

This extension reads that file in-memory using sql.js (pure WebAssembly SQLite — no native bindings required). It uses FTS5 full-text search for speed, falling back to a LIKE scan when FTS5 is unavailable.

Session titles and turns from currently-open sessions (not yet written to the database) are read directly from the per-workspace chatSessions/*.jsonl files.

Extension Settings

No configuration required.
