Meta Pet

Meta Pet helps owners turn everyday pet-care observations into useful next steps. Meals, walks, training and notes for the next visit are easy to scatter across chats and calendars. The app brings a pet's profile, preferences and device-local care timeline together. Muse Pet, its AI companion, uses that context to ask for missing details and prepare care entries or future appointment notes. The owner reviews each proposal before saving it; a suggestion does not become completed care by itself. Meta's Muse Spark powers live guidance and validated structured proposals. Muse Image creates a custom companion portrait from a selected image. Verified Facebook accounts can review or clear bounded private memory for each pet page; full profiles, timelines and chat remain device-local. Public owner sign-in, live replies, avatar generation from nonprivate sample artwork, saved-note approval and same-browser return have dated verification. The public demo is supervised and requires an accepted Facebook tester or owner for live features: https://petaverse-meta-pet-demo.vercel.app. The current source passed 325 tests, TypeScript and lint on 4 November. Physical-device behavior remains untested. WhatsApp infrastructure is implemented but disabled and unconfigured; no delivery is verified. Hardware, real payments, cryptocurrency and social publishing remain future integrations. Meta Pet is the app, Muse Pet the companion and Petaverse the wider ecosystem. Adoption, time savings and animal-health outcomes have not been measured. Earlier-work disclosure: the local prototype began on 22 October 2026, before the 26 October kickoff, with the initial app, local care records, onboarding, artwork and saved conversations, followed by initial live Muse, avatar and social-draft work. During the event it expanded with pet-specific context, reviewed actions, controlled discovery, private per-pet account memory, handoff safeguards, interactive guidance and the public Facebook-connected demo. Original development and verification records are retained.
