Copilot Token Tracker — Visual Studio Extension

Tracks your GitHub Copilot token usage directly inside Visual Studio 2022+. Reads local Copilot Chat session files and displays usage statistics in a dedicated tool window.

Status: Early access / active development. Core tracking is functional; some features available in the VS Code extension are still in progress.

Install

The extension will be published to the Visual Studio Marketplace. Until then, build from source (see Contributing).

Features

• Token usage tracking from Visual Studio Copilot Chat session files
• Today's and monthly token counts displayed in a tool window
• Per-model usage breakdown

Note on token counts: Visual Studio Copilot Chat session files store prompts and responses as plain text but do not include the actual LLM token counts used by the API. All numbers shown are estimated from prompt and response text length using model-specific character-to-token ratios.

Screenshots

Features:

1. Toolbar with found token counts in the format X | Y Which is today: X tokens | last 30-days: Y tokens

2. Detailed usage breakdown in the tool window, showing estimated tokens by model and date.

Supported VS Versions

• Visual Studio 2022 (v17.x and later)

Session File Location

Visual Studio Copilot Chat stores session files in:

<solution folder>\.vs\<solution name>.<ext>\copilot-chat\<hash>\sessions\<uuid>

The extension automatically discovers all sessions under the .vs folder for each open solution.

Known Limitations

• Token counts are estimated, not actual LLM API counts. See the note above.
• Features available in the VS Code extension that are not yet available here:
  • Cloud backend (Azure Storage sync)
  • Usage Analysis Dashboard
  • Copilot Fluency Score
  • Export / social sharing
  • Diagnostic reporting panel
