Features

📊 Real-time Token Tracking

Displays current day and 30-day token usage directly in the VS Code status bar.

🤖 Multi-Provider Support

Track usage across AI coding assistants simultaneously:

Provider	Data Source	Token Data
GitHub Copilot	`workspaceStorage/*/chatSessions/` (VS Code, Cursor, VSCodium, Insiders)	Actual counts when available, else estimated
Antigravity	`~/.gemini/antigravity/brain/`	Estimated from conversation text
Claude Code	`~/.claude/projects/`	Actual input/output/cache token counts
Codex	`~/.codex/sessions/`	Actual usage snapshots from local Codex rollouts

📈 Dashboard Views

Main Dashboard - Token totals, cost estimates, provider breakdown, model usage
Interactive Charts - Daily usage bars, stacked model breakdown, provider doughnut
Diagnostics - System info, session file discovery, cache stats, JSON export

💰 Cost Estimation

Per-model pricing for 30+ models across OpenAI, Anthropic, and Google:

Cache-aware pricing (Anthropic prompt caching, OpenAI prefix matching)
Input/output token cost breakdown
Daily and projected yearly cost

Session Log Locations

GitHub Copilot

Supported IDEs (sessions stored as JSON — readable):

IDE	Linux	macOS	Windows
VS Code	`~/.config/Code/User/workspaceStorage/`	`~/Library/Application Support/Code/User/workspaceStorage/`	`%APPDATA%\Code\User\workspaceStorage\`
VS Code Insiders	`~/.config/Code - Insiders/User/workspaceStorage/`	`~/Library/Application Support/Code - Insiders/User/workspaceStorage/`	`%APPDATA%\Code - Insiders\User\workspaceStorage\`
Cursor	`~/.config/Cursor/User/workspaceStorage/`	`~/Library/Application Support/Cursor/User/workspaceStorage/`	`%APPDATA%\Cursor\User\workspaceStorage\`
VSCodium	`~/.config/VSCodium/User/workspaceStorage/`	`~/Library/Application Support/VSCodium/User/workspaceStorage/`	`%APPDATA%\VSCodium\User\workspaceStorage\`

WSL is also supported — the extension automatically scans Windows-side AppData paths via /mnt/c/Users/.

Not supported (binary session formats, not parseable):

IDE	Reason
JetBrains (PyCharm, WebStorm, PhpStorm, IntelliJ…)	Sessions stored in Xodus binary DB (`.idea/copilot/chatSessions/`), no JSON files
Visual Studio	Sessions stored as binary files (`.vs/<project>/copilot-chat/sessions/`)

Antigravity

All platforms: ~/.gemini/antigravity/brain/{conversation-id}/.system_generated/logs/overview.txt

Claude Code

All platforms: ~/.claude/projects/{project}/*.jsonl
