You shouldn't have to explain your pet from scratch every time. PetOS remembers useful context about your pet and uses it to make everyday care and health guidance more personal over time. HELP THAT STARTS WITH YOUR PET Ask about training, feeding, behavior, grooming, routines, medications, and everyday care. PetOS can use details it already knows about your pet, including breed, age, health history, routines, and other relevant context. That means answers can start with your pet instead of starting with generic advice. WHEN SOMETHING FEELS WRONG Describe what is happening in plain language. PetOS asks relevant follow up questions, helps you understand how urgent the situation may be, and gives you clear next steps. Known details such as age, weight, medications, allergies, and past health context can help PetOS start further ahead. You do not have to repeat the same information every time. IT GETS MORE USEFUL OVER TIME A question today can become useful context later. Health events, records, measurements, and details PetOS learns through your interactions can help future guidance start with more of the story already in place. The goal is not just to store information. The goal is to make what PetOS knows useful the next time you need help. KEEP IMPORTANT HISTORY TOGETHER Track important changes over time, including weight, medications, health events, and other records. Past information stays connected to your pet so it can remain useful as their needs change. CARE ACROSS PEOPLE Invite a co parent, sitter, or other caregiver and choose what they can access for a specific pet. Share the context they need to care for your pet without explaining everything again from the beginning. PET HEALTH DECISION SUPPORT PetOS provides decision support, not a diagnosis or replacement for a veterinarian. If your pet may be experiencing an emergency, contact a veterinarian or emergency veterinary service. PetOS is designed to take potential risk seriously and help you understand when veterinary care may be needed. YOUR PET, OVER TIME Your pet changes. PetOS can learn with them. What PetOS learns today can make tomorrow's guidance more useful. ## Key features - Symptom triage for dogs and cats - Daily health check-ins - Pet health timeline - Vet visit notes - Vet-ready summaries - Vet cost estimates - Care plan reminders ## Frequently asked questions about PetOS ### What is PetOS?
