Setvia

Setvia is a collaborative planning and decision-making application built from scratch during the Meta Global AI Developer Hackathon 2026. Inspired by the Filipino expression "drawing lang," which describes plans that never happen, Setvia addresses a familiar problem: groups struggle to turn discussions into actual plans because of conflicting schedules, budgets, responsibilities, and personal constraints. At its core, Setvia uses Meta's Muse Spark 1.3 (muse-spark-1.3) through the Meta Model API. Its multimodal capabilities allow users to upload an invitation or event image and automatically extract planning information, including dates, locations, budgets, and other relevant details. For collaborative planning, Setvia implements five specialized AI roles powered by the same Muse Spark model: Listener, Judge, Negotiator, Question Strategist, and Speaker. These roles operate conditionally to interpret participant input, evaluate conflicting requirements, explore alternatives, identify missing information, and communicate actionable questions. Rather than accepting model-generated conclusions blindly, Setvia uses structured-output validation, evidence checks, privacy-aware information handling, six deterministic Reality Checks, and versioned participant approvals. The result is a planning experience designed to help friends, families, students, professional teams, and event organizers move from scattered conversations toward decisions everyone can understand and review. Setvia's goal is simple: Make plans that survive the group chat.
