AI Credits Monitor
Real-time GitHub Copilot AI credits and Claude Code usage/cost estimate displayed in the VS Code status bar.
Features
- Status bar icon shows your AI usage at a glance
- Two providers in one place — GitHub Copilot and Claude Code, each with its own data source and per-model breakdown
- Hover the status bar icon to see both providers stacked in one panel: cost, requests, sessions, and input/output/cache tokens with per-item dollar amounts
- Click the status bar item to cycle the period between Today / This Week / This Month (applies to both providers)
- Usage Report — a webview with daily-consumption charts and per-model tables; switch between Copilot and Claude Code tabs there
- Copilot debug-logging prompt — if the Copilot Chat extension is installed but its debug file logging is off, the extension offers a one-click button to enable it (otherwise VS Code Copilot usage can't be collected)
- Providers auto-hide when unavailable: only sources with actual local data are shown
- Auto-refreshes every 5 minutes (configurable)
Installation
Install from the VS Code Marketplace by searching for AI Credits Monitor, or install manually:
code --install-extension ai-credits-monitor-0.7.0.vsix
Once installed, the extension activates automatically — look for the $(pulse) icon in the right side of your status bar.

How It Works
Everything runs entirely offline — no network requests are made.
| Provider |
Data source |
Metric |
| Copilot |
VS Code debug logs (workspaceStorage/**/GitHub.copilot-chat/debug-logs/**/main.jsonl) + Copilot CLI SQLite db (~/.copilot/session-store.db, table assistant_usage_events) |
AI Credits (copilotUsageNanoAiu / total_nano_aiu, ÷1e9). Both sources use the same credit unit and are merged into one figure. Other IDEs (IntelliJ, etc.) not included. |
| Claude Code |
Session logs (~/.claude/projects/**/*.jsonl), CLI + IDE sessions |
Est. API-equivalent cost from per-model token pricing (input/output/cache read/cache write). Cloud sessions are not included; subscription plans are not actually billed per token — treat as an estimate. |
The Copilot CLI database is SQLite in WAL mode; the extension reads it via sql.js (pure WASM, no native build) and merges any uncommitted WAL pages so active-session usage is counted.
Claude Code records are deduplicated by message ID, so resumed sessions are not double-counted.
