When a Sri Lankan parent leaves to work abroad, the main switch, water pump, bills and emergency contacts often remain in one person’s head. Voice notes can preserve instructions, but the family still needs to find the right information and practise before it is needed. The person leaving films their home while explaining it in Sinhala or English. If I Disappear turns that walkthrough into an owner-reviewed handover, then answers a practical question: “If I left tomorrow, what would stop?” Five Meta models work together. Muse Spark extracts structured facts linked to the owner’s words and video frames. SAM 3.1 checks the referenced objects and tracks them through clips. Muse Wonder provides a second reading of facts marked as safety-related. Muse Voice Transcribe handles English speech, while Meta’s open-weights Omnilingual ASR supports Sinhala. The distinctive feature is how those outputs are checked: Spark’s proposed object location is compared with SAM’s segmentation, quotations are checked against the transcript, and disagreements are surfaced for owner review. The pipeline also includes secret redaction, card blurring and rules against medical instructions. A readiness board shows uncovered jobs, simulates the absence and creates a prioritised teaching plan. Family members check their understanding by identifying objects in photos and explaining the recorded steps. Web help retrieves owner-approved task instructions, while QR stickers open the relevant guide—including offline on a phone that has saved the pack. The project also includes a WhatsApp integration. Tested on a real Sri Lankan home: phone footage was processed into AC-servicing, main-switch and CCTV jobs, with object outlines, recorded instructions and a calculated first-problem date. Judges can explore that working home and its evidence. Separately, scripted live browser runs against Meta’s API passed 76/76 checks in each interface language. The repository includes 371 automated checks. One recorded 48-second end-to-end test used $0.34 in model calls. Try the deployed app: If I Disappear The sample requires no sign-up or API key and includes a guided tour. ## More from Meta Global AI Developer Hackathon - [KARTS AI ENTERPRISE](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/655) - [Team FixLens](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/656) - [Hades Corporation](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/657) - [Mouse Potato](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/659) - [Apex Studio](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/660) - [S4 Neighborhood Intelligence](https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/661) --- Markdown version of https://cerebralvalley.ai/e/meta-ai-developer-hackathon/hackathon/gallery/658.
