Turn invisible AI collaboration into a visible story of impact.
One command generates a polished report on what you built with Copilot, the skills it augmented, and the leverage it delivered.
"In March, Copilot delivered $4,380 worth of professional services for a $39/mo seat — a 112× return on investment." — Real output from this tool
"Where did the tokens go? What am I actually building with Copilot? Am I accessing skills I didn't have before?"
If you can't answer these confidently, you're not alone. Most developers know Copilot helps — but can't show how much, at what, or why it matters. This tool turns your local session logs into a single report that makes the invisible visible — what got built, what skills were augmented, and what it would have cost to do it alone.
Built for anyone who works with Copilot — developers, PMs, analysts, vibe coders, and anyone building with AI. Use it to recap what you created, share progress with your team and manager, or generate evidence for performance reviews. If Copilot helped you build it, this tool makes sure the story gets told.
Every project broken down into tasks with human effort equivalents — see that a 10-minute Copilot session replaced 3 hours of manual work. The ROI banner distills it to one number: how many multiples of your $39/mo seat Copilot delivered in professional services value.
Tangible artifacts — scripts, reports, documents, presentations, config files — categorized and counted. Not "Copilot helped me code" but "Copilot helped me ship 4 Python modules, 2 HTML reports, and a PowerShell deployment script."
Hours of assistance mapped across 20+ professional roles — Software Engineer, Data Analyst, UX Designer, Solutions Architect, and more. See exactly which disciplines Copilot staffed for you, on demand, at zero headcount cost.
Every interaction classified by intent — Building, Researching, Designing, Investigating, Iterating, Shipping. Discover your collaboration signature and whether Copilot is an always-on tax or a targeted force multiplier.
Time-of-day activity patterns with a daily heatmap — spot whether you're an early-morning builder or a late-night debugger, and whether AI assistance is concentrated or spread across your day.
Collapsible estimation detail showing the quantitative signals behind every effort number — tool invocations, premium requests, token volumes, and the deterministic formula. Evidence that Copilot isn't just handling boilerplate — it's tackling real complexity.

| Requirement | Why |
|---|---|
| Python 3.10+ | Core runtime |
GitHub CLI (gh) |
Provides API token for AI analysis — run gh auth login |
| GitHub Copilot | Session data source — must have active sessions in ~/.copilot/session-state/ |
| Microsoft Outlook | (Optional) For --email delivery via COM automation — auto-detects recipient from GitHub auth |
No pip install needed — the core report generator (harvest.py, analyze.py, report.py, whatidid.py) uses only the Python standard library + GitHub Models API.
This tool ships as a Copilot CLI agent. Anyone who clones the repo gets it automatically — run /agent in Copilot CLI and select whatidid, or just ask naturally:
"What did I build this week?"
See .github/agents/whatidid.agent.md for the agent definition.
