Castellan AI: Home Maintenance

Your home has a lot to remember. Castellan researches the appliances, systems, and important items you actually own, builds personalized maintenance plans, and reminds you what matters next. Start with a photo, description, or PDF. Castellan uses AI to organize useful item details and draft care based on the evidence you provide. Every AI-assisted result stays editable, so you remain in control. YOUR HOME, HANDLED • Add appliances, systems, materials, and other important home items. • Keep model details, manuals, receipts, warranties, ownership records, and photos together. • Search your saved items whenever you need them. PERSONALIZED CARE PLANS • Create recurring maintenance schedules for your real equipment. • Understand timing, effort, benefits, supplies, and safety considerations. • Complete, skip, or remind yourself later as your plans change. REMINDERS WITHOUT THE NOISE • See what is due today, scheduled, pending, or completed. • Receive timely maintenance notifications. • Add an optional maintenance calendar feed to your calendar. YOUR HOME HISTORY • Keep notes, photos, documents, and completed maintenance alongside the affected item. • Keep useful context attached to your home instead of scattered across drawers and inboxes. AI GUIDANCE YOU CONTROL Castellan provides organizational and general informational guidance. AI-assisted results may be incomplete or inaccurate and do not replace manufacturer instructions, professional inspections, qualified repair services, or emergency assistance.
