Use when someone asks how they can stay in Thailand or which Thai visa or route fits them, e.g. "how can I stay in Thailand for a year", "which visa do I need to retire in Thailand", "can I live in Thailand as a remote worker", "I am married to a Thai, how do I stay", "DTV or LTR or Thailand Privilege for me", "how long can I stay visa-free". Ranks the seven legal routes (30-day exemption + extension, tourist visa, DTV, Non-O retirement, Non-O marriage/Thai family, LTR, Thailand Privilege) with the same rules and ranking as the Visa Map on thailandstayplan.com: for each route whether it fits, why, what to watch, 5-year or per-trip cost, time to get it, core papers, insurance rule, and the public sources with their check date. Inputs: nationality as the user says it, age, planned stay, savings and income as numbers (Thai baht; convert other currencies at today's rate and tell the user), remote work, Thai spouse or child, budget. If nationality, age, stay or every money figure is missing, the tool returns one question to ask the user (scope needs_input); do not guess them. Thailand only. Information with sources, not legal advice; it recommends no agent, insurer or product.
