10-day journey building agent OS with model comparison
In-depth 10-day journey by Daniel Sánchez (@disier) building a personal agent OS with extensive model comparison. Tested in production: Claude 4.5 Opus (powerful but $167/10 days), Gemini (winner - massive context, low cost, stable for daily tasks), Codex and Ollama Cloud (failed in real agent workflows with loops and context loss). Key insight: future is orchestration - knowing when to use expensive power vs efficient models. Content in Spanish. Valuable real-world performance data.

Built StumbleReads.com from phone while putting baby to sleep
Developer @vallver built and deployed a complete website (StumbleReads.com) entirely from their phone while putting their baby to sleep. Demonstrates the power of mobile-first AI development using text message commands to an OpenClaw agent. Agent handled all coding, GitHub commits, and deployment without requiring a laptop or desktop. Perfect example of parenting + productivity.
Morning briefing — pulls weather, calendar, email, RSS, GitHub, Hacker News into daily summary
One of the most popular OpenClaw use cases: an automated morning briefing that aggregates data from multiple sources into a single daily summary. Agent pulls weather forecasts, calendar appointments, unread emails, RSS feed updates, GitHub activity, and Hacker News top stories, then delivers a consolidated morning briefing. Saves 20-30 minutes daily and ensures nothing important is missed. Commonly runs as a cron job or heartbeat task.
Real estate listing monitoring and alerts
Automated real estate monitoring system that continuously scans property listing websites for new properties matching specific criteria (location, price range, features). Agent sends instant notifications when matching properties appear, often faster than email alerts from real estate sites. Uses browser automation to navigate listing sites, compare listings against saved criteria, and notify via preferred channel (Slack, Discord, email, SMS). Particularly valuable in competitive markets where speed matters.
