 ## Demo
 
 See [demo/demo.cast](demo/demo.cast) — play with: `asciinema play demo/demo.cast`
 
 > **Live demo:** This repository is maintained by RepoKeeper itself — every issue, PR, and review goes through the same pipeline you can deploy in minutes.
 
+## Interactive Playground
+
+**Try it live** — paste a GitHub issue or PR diff and see RepoKeeper's AI in action, no deployment required.
+
+Once running, visit `http://your-server:3001/playground` to try issue triage and PR summarisation instantly.
+
+Set `attribution.playgroundUrl` in your config to link the playground from every AI-generated comment.

 ## The Problem
 
 Maintainers are drowning. AI-generated pull requests, duplicate issues, low-effort bug reports, and community questions pile up faster than any human can triage them. In 2026, the average popular open source repo receives more noise than signal — and maintainer burnout is at an all-time high.
