✨ What Agent 3 can do for you:
✅ Run autonomously for up to 200 minutes – 10x more autonomy than before.
✅ Test and fix its own work in a real browser – 3x faster and 10x more cost-effective than older testing models.
✅ Build Agents & Automations – create Slack bots, Telegram bots, or workflows triggered by events or time.
✅ Prototype and build apps quickly – go from idea → working software without the long setup.
✅ Deploy internal tools or MVPs fast – validate ideas before committing big resources.
✅ Live Monitoring – track progress in real time, even on mobile with the Replit app.
✅ Works like a collaborator – feels closer to working with a teammate than just a computer.
