- Sessions: unified browser for Copilot CLI, VS Code Copilot Chat, and Claude Code conversations, including extended-thinking blocks where supported
- Analytics: eight charts covering daily activity, hour-of-day, tools, models, top directories, time per branch/repo, and MCP servers
- Tokens: real API-reported token usage parsed from local logs, with daily/weekly/monthly views, model breakdown, and an estimated upstream API cost
- Effectiveness Score: 0 to 100 score per repo with improvement tips
- Export: single-session OpenAI-style chat JSONL, suitable as SFT data
About the cost number: GitHub Copilot bills on premium requests, not tokens. The cost shown is what you'd pay calling Anthropic / OpenAI / Google directly with the same usage. Useful as a reference, not your GitHub bill.
